A pipeline is a system of pipes for long distance transportation of a liquid or gas, typically to a market area for consumption. The latest data from 2014 gives a total of slightly less than of pipeline in 120 countries around the world. The United States had 65%, Russia had 8%, and Canada had 3%, thus 76% of all pipeline were in these three countries. Pipeline and Gas Journal'''s worldwide survey figures indicate that of pipelines are planned and under construction. Of these, represent projects in the planning and design phase; reflect pipelines in various stages of construction. Liquids and gases are transported in pipelines, and any chemically stable substance can be sent through a pipeline. Pipelines exist for the transport of crude and refined petroleum, fuels – such as oil, natural gas and biofuels – and other fluids including sewage, slurry, water, beer, hot water or steam for shorter distances. Pipelines are useful for transporting water for drinking or irrigation over long distances when it needs to move over hills, or where canals or channels are poor choices due to considerations of evaporation, pollution, or environmental impact. Oil pipelines are made from steel or plastic tubes which are usually buried. The oil is moved through the pipelines by pump stations along the pipeline. Natural gas (and similar gaseous fuels) are pressurized into liquids known as natural gas liquids (NGLs). Natural gas pipelines are constructed of carbon steel. Hydrogen pipeline transport is the transportation of hydrogen through a pipe. Pipelines are one of the safest ways of transporting materials as compared to road or rail, and hence in war, pipelines are often the target of military attacks. Oil and natural gas
It is well documented when the first crude oil pipeline was built. Credit for the development of pipeline transport belongs indisputably to the Oil Transport Association, which first constructed a wrought iron pipeline over a 6 mile (10 km) track from an oil field in Pennsylvania to a railroad station in Oil Creek, in the 1860s. Pipelines are generally the most economical way to transport large quantities of oil, refined oil products or natural gas over land. For example, in 2014, pipeline transport of crude oil cost about $5 per barrel, while rail transport cost about $10 to $15 per barrel. Trucking has even higher costs due to the additional labor required; employment on completed pipelines represents only "1% of that of the trucking industry.". In the United States, 70% of crude oil and petroleum products are shipped by pipeline. (23% are by ship, 4% by truck, and 3% by rail) In Canada for natural gas and petroleum products, 97% are shipped by pipeline. As more North American pipelines are built, even more exports of LNG, propane, butane, and other natural gas products occur on all three US coasts. To give insight, North Dakota Bakken region's oil production has grown by 600% from 2007 to 2015. North Dakota oil companies are shipping huge amounts of oil by tanker rail car as they can direct the oil to the market that gives the best price, and rail cars can be used to avoid a congested oil pipeline to get the oil to a different pipeline in order to get the oil to market faster or to a different less busy oil refinery. However, pipelines provide a cheaper means to transport by volume. Enbridge in Canada is applying to reverse an oil pipeline going from east to west (Line 9) and expanding it and using it to ship western Canadian bitumen oil eastward. From a presently rated 250,000 barrels equivalent per day pipeline, it will be expanded to between 1.0 and 1.3 million barrels per day. It will bring western oil to refineries in Ontario, Michigan, Ohio, Pennsylvania, Quebec and New York by early 2014. New Brunswick will also refine some of this western Canadian crude and export some crude and refined oil to Europe from its deep water oil ULCC loading port. Although pipelines can be built under the sea, that process is economically and technically demanding, so the majority of oil at sea is transported by tanker ships. Similarly, it is often more economically feasible to transport natural gas in the form of LNG, however the break even point between LNG and pipelines would depend on the volume of natural gas and the distance it travels. Growth of market
The market size for oil and gas pipeline construction experienced tremendous growth prior to the economic downturn in 2008. After faltering in 2009, demand for pipeline expansion and updating increased the following year as energy production grew. By 2012, almost 32,000 miles (51500 km) of North American pipeline were being planned or under construction. When pipelines are constrained, additional pipeline product transportation options may include the use of drag reducing agents, or by transporting product via truck or rail. Construction and operation
Oil pipelines are made from steel or plastic tubes with inner diameter typically from Most pipelines are typically buried at a depth of about To protect pipes from impact, abrasion, and corrosion, a variety of methods are used. These can include wood lagging (wood slats), concrete coating, rockshield, high density polyethylene, imported sand padding, sacrificial cathodes and padding machines. Crude oil contains varying amounts of paraffin wax and in colder climates wax buildup may occur within a pipeline. Often these pipelines are inspected and cleaned using pigging, the practice of using devices known as "pigs" to perform various maintenance operations on a pipeline. The devices are also known as "scrapers" or "Go devils". "Smart pigs" (also known as "intelligent" or "intelligence" pigs) are used to detect anomalies in the pipe such as dents, metal loss caused by corrosion, cracking or other mechanical damage. These devices are launched from pig launcher stations and travel through the pipeline to be received at any other station down stream, either cleaning wax deposits and material that may have accumulated inside the line or inspecting and recording the condition of the line. For natural gas, pipelines are constructed of carbon steel and vary in size from in diameter, depending on the type of pipeline. The gas is pressurized by compressor stations and is odorless unless mixed with a mercaptan odorant where required by a regulating authority. Ammonia
A major ammonia pipeline is the Ukrainian Transammiak line connecting the TogliattiAzot facility in Russia to the exporting Black Sea port of Odesa. Alcohol fuels
Pipelines have been used for transportation of ethanol in Brazil, and there are several ethanol pipeline projects in Brazil and the United States. The main problems related to the transport of ethanol by pipeline are its corrosive nature and tendency to absorb water and impurities in pipelines, which are not problems with oil and natural gas. Insufficient volumes and cost effectiveness are other considerations limiting construction of ethanol pipelines. In the US minimal amounts of ethanol are transported by pipeline. Most ethanol is shipped by rail, the main alternatives being truck and barge. Delivering ethanol by pipeline is the most desirable option, but ethanol's affinity for water and solvent properties require the use of a dedicated pipeline, or significant cleanup of existing pipelines. Coal and ore
Slurry pipelines are sometimes used to transport coal or ore from mines. The material to be transported is closely mixed with water before being introduced to the pipeline; at the far end, the material must be dried. One example is a slurry pipeline which is planned to transport iron ore from the Minas Rio mine (producing 26.5 million tonnes per year) to the Port of Açu in Brazil. An existing example is the Savage River Slurry pipeline in Tasmania, Australia, possibly the world's first when it was built in 1967. It includes a bridge span at above the Savage River. Hydrogen
Hydrogen pipeline transport is a transportation of hydrogen through a pipe as part of the hydrogen infrastructure. Hydrogen pipeline transport is used to connect the point of hydrogen production or delivery of hydrogen with the point of demand, with transport costs similar to CNG, the technology is proven. Most hydrogen is produced at the place of demand with every 50 to 100 mile (161 km) an industrial production facility. The 1938 Rhine Ruhr hydrogen pipeline is still in operation. as of 2004, there are 900 mile (1448 km) of low pressure hydrogen pipelines in the US and 930 mile (1497 km) in Europe. Water
Two millennia ago, the ancient Romans made use of large aqueducts to transport water from higher elevations by building the aqueducts in graduated segments that allowed gravity to push the water along until it reached its destination. Hundreds of these were built throughout Europe and elsewhere, and along with flour mills were considered the lifeline of the Roman Empire. The ancient Chinese also made use of channels and pipe systems for public works. The famous Han dynasty court eunuch Zhang Rang (d. 189 AD) once ordered the engineer Bi Lan to construct a series of square pallet chain pumps outside the capital city of Luoyang. These chain pumps serviced the imperial palaces and living quarters of the capital city as the water lifted by the chain pumps was brought in by a stoneware pipe system. Pipelines are useful for transporting water for drinking or irrigation over long distances when it needs to move over hills, or where canals or channels are poor choices due to considerations of evaporation, pollution, or environmental impact. The Goldfields Water Supply Scheme in Western Australia using 750 mm (30 inch) pipe and completed in 1903 was the largest water supply scheme of its time. Examples of significant water pipelines in South Australia are the Morgan Whyalla pipeline (completed 1944) and Mannum Adelaide pipeline (completed 1955) pipelines, both part of the larger Snowy Mountains scheme. There are two Los Angeles, California aqueducts, the Owens Valley aqueduct (completed 1913) and the Second Los Angeles Aqueduct (completed 1970) which also include extensive use of pipelines. The Great Manmade River of Libya supplies of water each day to Tripoli, Benghazi, Sirte, and several other cities in Libya. The pipeline is over long, and is connected to wells tapping an aquifer over underground. Other systems
District heating
District heating or teleheating systems consist of a network of insulated feed and return pipes which transport heated water, pressurized hot water, or sometimes steam to the customer. While steam is hottest and may be used in industrial processes due to its higher temperature, it is less efficient to produce and transport due to greater heat losses. Heat transfer oils are generally not used for economic and ecological reasons. The typical annual loss of thermal energy through distribution is around 10%, as seen in Norway's district heating network. District heating pipelines are normally installed underground, with some exceptions. Within the system, heat storage may be installed to even out peak load demands. Heat is transferred into the central heating of the dwellings through heat exchangers at heat substations, without mixing of the fluids in either system. Beer
Bars in the Veltins Arena, a major football ground in Gelsenkirchen, Germany, are interconnected by a long beer pipeline. In Randers city in Denmark, the so called Thor Beer pipeline was operated. Originally, copper pipes ran directly from the brewery, but when the brewery moved out of the city in the 1990s, Thor Beer replaced it with a giant tank. A three kilometer beer pipeline was completed in Bruges, Belgium in September 2016 to reduce truck traffic on the city streets. Brine
The village of Hallstatt in Austria, which is known for its long history of salt mining, claims to contain "the oldest industrial pipeline in the world", dating back to 1595. It was constructed from 13,000 hollowed out tree trunks to transport brine from Hallstatt to Ebensee. Milk
Between 1978 and 1994, a 15 km milk pipeline ran between the Dutch island of Ameland and Holwerd on the mainland, of which 8 km was beneath the Wadden Sea. Every day, 30,000 litres of milk produced on the island were transported to be processed on the mainland. In 1994, the pipeline was abandoned. Marine pipelines
In places, a pipeline may have to cross water expanses, such as small seas, straits and rivers. In many instances, they lie entirely on the seabed. These pipelines are referred to as "marine" pipelines (also, "submarine" or "offshore" pipelines). They are used primarily to carry oil or gas, but transportation of water is also important. The former is an intrafield pipeline, in the sense that it is used to connect subsea wellheads, manifolds and the platform within a particular development field. The latter, sometimes referred to as an "export pipeline", is used to bring the resource to shore. Russia has "Pipeline Troops" as part of the Rear Services, who are trained to build and repair pipelines. Russia is the only country to have Pipeline Troops. The U. S. government, mainly through the EPA, the FERC and others, reviews proposed pipeline projects in order to comply with the Clean Water Act, the National Environmental Policy Act, other laws and, in some cases, municipal laws. The Biden administration has sought to permit the respective states and tribal groups to appraise and potentially block the proposed projects. Operation
Field devices are instrumentation, data gathering units and communication systems. The field instrumentation includes flow, pressure, and temperature gauges/transmitters, and other devices to measure the relevant data required. These instruments are installed along the pipeline on some specific locations, such as injection or delivery stations, pump stations (liquid pipelines) or compressor stations (gas pipelines), and block valve stations. The information measured by these field instruments is then gathered in local remote terminal units (RTU) that transfer the field data to a central location in real time using communication systems, such as satellite channels, microwave links, or cellular phone connections. Pipelines are controlled and operated remotely, from what is usually known as the "Main Control Room". In this center, all the data related to field measurement is consolidated in one central database. The data is received from multiple RTUs along the pipeline. It is common to find RTUs installed at every station along the pipeline. The SCADA system at the Main Control Room receives all the field data and presents it to the pipeline operator through a set of screens or Human Machine Interface, showing the operational conditions of the pipeline. The operator can monitor the hydraulic conditions of the line, as well as send operational commands (open/close valves, turn on/off compressors or pumps, change setpoints, etc.) through the SCADA system to the field. To optimize and secure the operation of these assets, some pipeline companies are using what is called "Advanced Pipeline Applications", which are software tools installed on top of the SCADA system, that provide extended functionality to perform leak detection, leak location, batch tracking (liquid lines), pig tracking, composition tracking, predictive modeling, look ahead modeling, and operator training. Technology
Components
Pipeline networks are composed of several pieces of equipment that operate together to move products from location to location. The main elements of a pipeline system are:
Initial injection station Known also as "supply" or "inlet" station, is the beginning of the system, where the product is injected into the line. Storage facilities, pumps or compressors are usually located at these locations. Compressor/pump stations Pumps for liquid pipelines and compressors for gas pipelines, are located along the line to move the product through the pipeline. The location of these stations is defined by the topography of the terrain, the type of product being transported, or operational conditions of the network. Partial delivery station Known also as "intermediate stations", these facilities allow the pipeline operator to deliver part of the product being transported. Block valve station These are the first line of protection for pipelines. With these valves the operator can isolate any segment of the line for maintenance work or isolate a rupture or leak. Block valve stations are usually located every 20 to 30 mile (48 km), depending on the type of pipeline. Even though it is not a design rule, it is a very usual practice in liquid pipelines. The location of these stations depends exclusively on the nature of the product being transported, the trajectory of the pipeline and/or the operational conditions of the line. Regulator station This is a special type of valve station, where the operator can release some of the pressure from the line. Regulators are usually located at the downhill side of a peak. Final delivery station Known also as "outlet" stations or terminals, this is where the product will be distributed to the consumer. It could be a tank terminal for liquid pipelines or a connection to a distribution network for gas pipelines. Leak detection systems
Since oil and gas pipelines are an important asset of the economic development of almost any country, it has been required either by government regulations or internal policies to ensure the safety of the assets, and the population and environment where these pipelines run. Pipeline companies face government regulation, environmental constraints and social situations. Government regulations may define minimum staff to run the operation, operator training requirements, pipeline facilities, technology and applications required to ensure operational safety. For example, in the State of Washington it is mandatory for pipeline operators to be able to detect and locate leaks of 8 percent of maximum flow within fifteen minutes or less. Social factors also affect the operation of pipelines. Product theft is sometimes also a problem for pipeline companies. In this case, the detection levels should be under two percent of maximum flow, with a high expectation for location accuracy. Various technologies and strategies have been implemented for monitoring pipelines, from physically walking the lines to satellite surveillance. The most common technology to protect pipelines from occasional leaks is Computational Pipeline Monitoring or CPM. CPM takes information from the field related to pressures, flows, and temperatures to estimate the hydraulic behavior of the product being transported. Once the estimation is completed, the results are compared to other field references to detect the presence of an anomaly or unexpected situation, which may be related to a leak. The American Petroleum Institute has published several articles related to the performance of CPM in liquids pipelines. The API Publications are:
RAM 1130 – Computational pipeline monitoring for liquids pipelines
API 1149 – Pipeline variable uncertainties & their effects on leak detectability
Where a pipeline containing passes under a road or railway, it is usually enclosed in a protective casing. This casing is vented to the atmosphere to prevent the build up of flammable gases or corrosive substances, and to allow the air inside the casing to be sampled to detect leaks. The casing vent, a pipe protruding from the ground, often doubles as a warning marker called a casing vent marker''.
Трубопровод – это система труб для транспортировки жидкости или газа на большие расстояния, как правило, к рыночной зоне для потребления. Последние данные за 2014 год указывают на общую протяженность трубопроводов чуть менее чем в 120 странах мира. На Соединенные Штаты приходилось 65%, на Россию – 8%, а на Канаду – 3%, таким образом, 76% всех трубопроводов находились в этих трех странах. Согласно всемирному обзору Pipeline and Gas Journal, планируется строительство новых трубопроводов. Из них проекты находятся на стадии планирования и проектирования, а остальные – на различных этапах строительства. По трубопроводам транспортируются жидкости и газы, и любое химически стабильное вещество может быть по ним перекачано. Существуют трубопроводы для транспортировки сырой и переработанной нефти, топлива – такого как нефть, природный газ и биотопливо, – а также других жидкостей, включая сточные воды, шламы, воду, пиво, горячую воду или пар на небольшие расстояния. Трубопроводы полезны для транспортировки питьевой или ирригационной воды на большие расстояния, когда необходимо преодолевать холмы, или когда каналы и водотоки являются неоптимальным решением из-за испарения, загрязнения или воздействия на окружающую среду. Нефтепроводы изготавливаются из стальных или пластиковых труб, которые обычно зарываются в землю. Нефть перемещается по трубопроводам с помощью насосных станций, расположенных вдоль трассы. Природный газ (и аналогичные газообразные топлива) сжимаются в жидкости, известные как сжиженные углеводородные газы (СУГ). Трубопроводы для природного газа изготавливаются из углеродистой стали. Транспортировка водорода по трубопроводам – это перемещение водорода по трубам. Трубопроводы – один из самых безопасных способов транспортировки материалов по сравнению с автомобильным или железнодорожным транспортом, поэтому во время войны трубопроводы часто становятся целью военных атак.

Block valve stations are usually located every 20 to 30 mile (48 km), depending on the type of pipeline. Even though it is not a design rule, it is a very usual practice in liquid pipelines. The location of these stations depends exclusively on the nature of the product being transported, the trajectory of the pipeline and/or the operational conditions of the line. Regulator station This is a special type of valve station, where the operator can release some of the pressure from the line. Regulators are usually located at the downhill side of a peak. Final delivery station Known also as "outlet" stations or terminals, this is where the product will be distributed to the consumer. It could be a tank terminal for liquid pipelines or a connection to a distribution network for gas pipelines. Leak detection systems
Since oil and gas pipelines are an important asset of the economic development of almost any country, it has been required either by government regulations or internal policies to ensure the safety of the assets, and the population and environment where these pipelines run. Pipeline companies face government regulation, environmental constraints and social situations. Government regulations may define minimum staff to run the operation, operator training requirements, pipeline facilities, technology and applications required to ensure operational safety. For example, in the State of Washington it is mandatory for pipeline operators to be able to detect and locate leaks of 8 percent of maximum flow within fifteen minutes or less. Social factors also affect the operation of pipelines. Product theft is sometimes also a problem for pipeline companies. In this case, the detection levels should be under two percent of maximum flow, with a high expectation for location accuracy. Various technologies and strategies have been implemented for monitoring pipelines, from physically walking the lines to satellite surveillance. The most common technology to protect pipelines from occasional leaks is Computational Pipeline Monitoring or CPM. CPM takes information from the field related to pressures, flows, and temperatures to estimate the hydraulic behavior of the product being transported. Once the estimation is completed, the results are compared to other field references to detect the presence of an anomaly or unexpected situation, which may be related to a leak. The American Petroleum Institute has published several articles related to the performance of CPM in liquids pipelines. The API Publications are:
RAM 1130 – Computational pipeline monitoring for liquids pipelines
API 1149 – Pipeline variable uncertainties & their effects on leak detectability
Where a pipeline containing passes under a road or railway, it is usually enclosed in a protective casing. This casing is vented to the atmosphere to prevent the build up of flammable gases or corrosive substances, and to allow the air inside the casing to be sampled to detect leaks. The casing vent, a pipe protruding from the ground, often doubles as a warning marker called a casing vent marker''.
Хорошо задокументировано, когда был построен первый нефтепровод. Признание за развитие трубопроводного транспорта принадлежит, несомненно, Oil Transport Association, которая в 1860-х годах впервые построила кованный железный трубопровод протяженностью 6 миль (10 км) от нефтяного месторождения в Пенсильвании до железнодорожной станции в Оил-Крик. Трубопроводы, как правило, являются наиболее экономичным способом транспортировки больших объемов нефти, нефтепродуктов или природного газа по суше. Например, в 2014 году транспортировка сырой нефти по трубопроводу стоила около 5 долларов за баррель, в то время как железнодорожная транспортировка – от 10 до 15 долларов за баррель. Автомобильные перевозки обходятся еще дороже из-за необходимости дополнительной рабочей силы; занятость на завершенных трубопроводах составляет всего "1% от занятости в автомобильном транспорте". В Соединенных Штатах 70% сырой нефти и нефтепродуктов транспортируется по трубопроводам (23% – морским транспортом, 4% – автомобильным транспортом и 3% – железнодорожным транспортом). В Канаде 97% природного газа и нефтепродуктов транспортируется по трубопроводам. По мере строительства новых североамериканских трубопроводов увеличивается экспорт СПГ, пропана, бутана и других продуктов переработки природного газа на всех трех побережьях США. Для справки, добыча нефти в регионе Баккен в Северной Дакоте выросла на 600% с 2007 по 2015 год. Нефтяные компании Северной Дакоты отправляют огромные объемы нефти по железнодорожным цистернам, поскольку они могут направить нефть на рынок, предлагающий наилучшую цену, а железнодорожные цистерны можно использовать для обхода перегруженного нефтепровода, чтобы доставить нефть на другой трубопровод для более быстрой доставки на рынок или на другой менее загруженный нефтеперерабатывающий завод. Однако трубопроводы обеспечивают более дешевый способ транспортировки в пересчете на объем. Компания Enbridge в Канаде подала заявку на изменение направления нефтепровода, идущего с востока на запад (линия 9), его расширение и использование для транспортировки битуминозной нефти с запада Канады на восток. Его пропускная способность увеличится с нынешних 250 000 баррелей в сутки до 1,0–1,3 миллиона баррелей в сутки. Он будет доставлять западную нефть на нефтеперерабатывающие заводы в Онтарио, Мичигане, Огайо, Пенсильвании, Квебеке и Нью-Йорке к началу 2014 года. Нью-Брансуик также будет перерабатывать часть этой западной канадской нефти и экспортировать часть сырой и переработанной нефти в Европу из своего глубоководного порта для загрузки супертанкеров. Хотя трубопроводы можно строить под водой, этот процесс экономически и технически сложен, поэтому большая часть нефти в море транспортируется танкерами. Аналогичным образом, часто экономически целесообразнее транспортировать природный газ в форме СПГ, однако точка безубыточности между СПГ и трубопроводами будет зависеть от объема природного газа и расстояния его транспортировки. Рост рынка
A pipeline is a system of pipes for long distance transportation of a liquid or gas, typically to a market area for consumption. The latest data from 2014 gives a total of slightly less than of pipeline in 120 countries around the world. The United States had 65%, Russia had 8%, and Canada had 3%, thus 76% of all pipeline were in these three countries. Pipeline and Gas Journal'''s worldwide survey figures indicate that of pipelines are planned and under construction. Of these, represent projects in the planning and design phase; reflect pipelines in various stages of construction. Liquids and gases are transported in pipelines, and any chemically stable substance can be sent through a pipeline. Pipelines exist for the transport of crude and refined petroleum, fuels – such as oil, natural gas and biofuels – and other fluids including sewage, slurry, water, beer, hot water or steam for shorter distances. Pipelines are useful for transporting water for drinking or irrigation over long distances when it needs to move over hills, or where canals or channels are poor choices due to considerations of evaporation, pollution, or environmental impact. Oil pipelines are made from steel or plastic tubes which are usually buried. The oil is moved through the pipelines by pump stations along the pipeline. Natural gas (and similar gaseous fuels) are pressurized into liquids known as natural gas liquids (NGLs). Natural gas pipelines are constructed of carbon steel. Hydrogen pipeline transport is the transportation of hydrogen through a pipe. Pipelines are one of the safest ways of transporting materials as compared to road or rail, and hence in war, pipelines are often the target of military attacks. Oil and natural gas
It is well documented when the first crude oil pipeline was built. Credit for the development of pipeline transport belongs indisputably to the Oil Transport Association, which first constructed a wrought iron pipeline over a 6 mile (10 km) track from an oil field in Pennsylvania to a railroad station in Oil Creek, in the 1860s. Pipelines are generally the most economical way to transport large quantities of oil, refined oil products or natural gas over land. For example, in 2014, pipeline transport of crude oil cost about $5 per barrel, while rail transport cost about $10 to $15 per barrel. Trucking has even higher costs due to the additional labor required; employment on completed pipelines represents only "1% of that of the trucking industry.". In the United States, 70% of crude oil and petroleum products are shipped by pipeline. (23% are by ship, 4% by truck, and 3% by rail) In Canada for natural gas and petroleum products, 97% are shipped by pipeline. As more North American pipelines are built, even more exports of LNG, propane, butane, and other natural gas products occur on all three US coasts. To give insight, North Dakota Bakken region's oil production has grown by 600% from 2007 to 2015. North Dakota oil companies are shipping huge amounts of oil by tanker rail car as they can direct the oil to the market that gives the best price, and rail cars can be used to avoid a congested oil pipeline to get the oil to a different pipeline in order to get the oil to market faster or to a different less busy oil refinery. However, pipelines provide a cheaper means to transport by volume. Enbridge in Canada is applying to reverse an oil pipeline going from east to west (Line 9) and expanding it and using it to ship western Canadian bitumen oil eastward. From a presently rated 250,000 barrels equivalent per day pipeline, it will be expanded to between 1.0 and 1.3 million barrels per day. It will bring western oil to refineries in Ontario, Michigan, Ohio, Pennsylvania, Quebec and New York by early 2014. New Brunswick will also refine some of this western Canadian crude and export some crude and refined oil to Europe from its deep water oil ULCC loading port. Although pipelines can be built under the sea, that process is economically and technically demanding, so the majority of oil at sea is transported by tanker ships. Similarly, it is often more economically feasible to transport natural gas in the form of LNG, however the break even point between LNG and pipelines would depend on the volume of natural gas and the distance it travels. Growth of market
The market size for oil and gas pipeline construction experienced tremendous growth prior to the economic downturn in 2008. After faltering in 2009, demand for pipeline expansion and updating increased the following year as energy production grew. By 2012, almost 32,000 miles (51500 km) of North American pipeline were being planned or under construction. When pipelines are constrained, additional pipeline product transportation options may include the use of drag reducing agents, or by transporting product via truck or rail. Construction and operation
Oil pipelines are made from steel or plastic tubes with inner diameter typically from Most pipelines are typically buried at a depth of about To protect pipes from impact, abrasion, and corrosion, a variety of methods are used. These can include wood lagging (wood slats), concrete coating, rockshield, high density polyethylene, imported sand padding, sacrificial cathodes and padding machines. Crude oil contains varying amounts of paraffin wax and in colder climates wax buildup may occur within a pipeline. Often these pipelines are inspected and cleaned using pigging, the practice of using devices known as "pigs" to perform various maintenance operations on a pipeline. The devices are also known as "scrapers" or "Go devils". "Smart pigs" (also known as "intelligent" or "intelligence" pigs) are used to detect anomalies in the pipe such as dents, metal loss caused by corrosion, cracking or other mechanical damage. These devices are launched from pig launcher stations and travel through the pipeline to be received at any other station down stream, either cleaning wax deposits and material that may have accumulated inside the line or inspecting and recording the condition of the line. For natural gas, pipelines are constructed of carbon steel and vary in size from in diameter, depending on the type of pipeline. The gas is pressurized by compressor stations and is odorless unless mixed with a mercaptan odorant where required by a regulating authority. Ammonia
A major ammonia pipeline is the Ukrainian Transammiak line connecting the TogliattiAzot facility in Russia to the exporting Black Sea port of Odesa. Alcohol fuels
Pipelines have been used for transportation of ethanol in Brazil, and there are several ethanol pipeline projects in Brazil and the United States. The main problems related to the transport of ethanol by pipeline are its corrosive nature and tendency to absorb water and impurities in pipelines, which are not problems with oil and natural gas. Insufficient volumes and cost effectiveness are other considerations limiting construction of ethanol pipelines. In the US minimal amounts of ethanol are transported by pipeline. Most ethanol is shipped by rail, the main alternatives being truck and barge. Delivering ethanol by pipeline is the most desirable option, but ethanol's affinity for water and solvent properties require the use of a dedicated pipeline, or significant cleanup of existing pipelines. Coal and ore
Slurry pipelines are sometimes used to transport coal or ore from mines. The material to be transported is closely mixed with water before being introduced to the pipeline; at the far end, the material must be dried. One example is a slurry pipeline which is planned to transport iron ore from the Minas Rio mine (producing 26.5 million tonnes per year) to the Port of Açu in Brazil. An existing example is the Savage River Slurry pipeline in Tasmania, Australia, possibly the world's first when it was built in 1967. It includes a bridge span at above the Savage River. Hydrogen
Hydrogen pipeline transport is a transportation of hydrogen through a pipe as part of the hydrogen infrastructure. Hydrogen pipeline transport is used to connect the point of hydrogen production or delivery of hydrogen with the point of demand, with transport costs similar to CNG, the technology is proven. Most hydrogen is produced at the place of demand with every 50 to 100 mile (161 km) an industrial production facility. The 1938 Rhine Ruhr hydrogen pipeline is still in operation. as of 2004, there are 900 mile (1448 km) of low pressure hydrogen pipelines in the US and 930 mile (1497 km) in Europe. Water
Two millennia ago, the ancient Romans made use of large aqueducts to transport water from higher elevations by building the aqueducts in graduated segments that allowed gravity to push the water along until it reached its destination. Hundreds of these were built throughout Europe and elsewhere, and along with flour mills were considered the lifeline of the Roman Empire. The ancient Chinese also made use of channels and pipe systems for public works. The famous Han dynasty court eunuch Zhang Rang (d. 189 AD) once ordered the engineer Bi Lan to construct a series of square pallet chain pumps outside the capital city of Luoyang. These chain pumps serviced the imperial palaces and living quarters of the capital city as the water lifted by the chain pumps was brought in by a stoneware pipe system. Pipelines are useful for transporting water for drinking or irrigation over long distances when it needs to move over hills, or where canals or channels are poor choices due to considerations of evaporation, pollution, or environmental impact. The Goldfields Water Supply Scheme in Western Australia using 750 mm (30 inch) pipe and completed in 1903 was the largest water supply scheme of its time. Examples of significant water pipelines in South Australia are the Morgan Whyalla pipeline (completed 1944) and Mannum Adelaide pipeline (completed 1955) pipelines, both part of the larger Snowy Mountains scheme. There are two Los Angeles, California aqueducts, the Owens Valley aqueduct (completed 1913) and the Second Los Angeles Aqueduct (completed 1970) which also include extensive use of pipelines. The Great Manmade River of Libya supplies of water each day to Tripoli, Benghazi, Sirte, and several other cities in Libya. The pipeline is over long, and is connected to wells tapping an aquifer over underground. Other systems
District heating
District heating or teleheating systems consist of a network of insulated feed and return pipes which transport heated water, pressurized hot water, or sometimes steam to the customer. While steam is hottest and may be used in industrial processes due to its higher temperature, it is less efficient to produce and transport due to greater heat losses. Heat transfer oils are generally not used for economic and ecological reasons. The typical annual loss of thermal energy through distribution is around 10%, as seen in Norway's district heating network. District heating pipelines are normally installed underground, with some exceptions. Within the system, heat storage may be installed to even out peak load demands. Heat is transferred into the central heating of the dwellings through heat exchangers at heat substations, without mixing of the fluids in either system. Beer
Bars in the Veltins Arena, a major football ground in Gelsenkirchen, Germany, are interconnected by a long beer pipeline. In Randers city in Denmark, the so called Thor Beer pipeline was operated. Originally, copper pipes ran directly from the brewery, but when the brewery moved out of the city in the 1990s, Thor Beer replaced it with a giant tank. A three kilometer beer pipeline was completed in Bruges, Belgium in September 2016 to reduce truck traffic on the city streets. Brine
The village of Hallstatt in Austria, which is known for its long history of salt mining, claims to contain "the oldest industrial pipeline in the world", dating back to 1595. It was constructed from 13,000 hollowed out tree trunks to transport brine from Hallstatt to Ebensee. Milk
Between 1978 and 1994, a 15 km milk pipeline ran between the Dutch island of Ameland and Holwerd on the mainland, of which 8 km was beneath the Wadden Sea. Every day, 30,000 litres of milk produced on the island were transported to be processed on the mainland. In 1994, the pipeline was abandoned. Marine pipelines
In places, a pipeline may have to cross water expanses, such as small seas, straits and rivers. In many instances, they lie entirely on the seabed. These pipelines are referred to as "marine" pipelines (also, "submarine" or "offshore" pipelines). They are used primarily to carry oil or gas, but transportation of water is also important. The former is an intrafield pipeline, in the sense that it is used to connect subsea wellheads, manifolds and the platform within a particular development field. The latter, sometimes referred to as an "export pipeline", is used to bring the resource to shore. Russia has "Pipeline Troops" as part of the Rear Services, who are trained to build and repair pipelines. Russia is the only country to have Pipeline Troops. The U. S. government, mainly through the EPA, the FERC and others, reviews proposed pipeline projects in order to comply with the Clean Water Act, the National Environmental Policy Act, other laws and, in some cases, municipal laws. The Biden administration has sought to permit the respective states and tribal groups to appraise and potentially block the proposed projects. Operation
Field devices are instrumentation, data gathering units and communication systems. The field instrumentation includes flow, pressure, and temperature gauges/transmitters, and other devices to measure the relevant data required. These instruments are installed along the pipeline on some specific locations, such as injection or delivery stations, pump stations (liquid pipelines) or compressor stations (gas pipelines), and block valve stations. The information measured by these field instruments is then gathered in local remote terminal units (RTU) that transfer the field data to a central location in real time using communication systems, such as satellite channels, microwave links, or cellular phone connections. Pipelines are controlled and operated remotely, from what is usually known as the "Main Control Room". In this center, all the data related to field measurement is consolidated in one central database. The data is received from multiple RTUs along the pipeline. It is common to find RTUs installed at every station along the pipeline. The SCADA system at the Main Control Room receives all the field data and presents it to the pipeline operator through a set of screens or Human Machine Interface, showing the operational conditions of the pipeline. The operator can monitor the hydraulic conditions of the line, as well as send operational commands (open/close valves, turn on/off compressors or pumps, change setpoints, etc.) through the SCADA system to the field. To optimize and secure the operation of these assets, some pipeline companies are using what is called "Advanced Pipeline Applications", which are software tools installed on top of the SCADA system, that provide extended functionality to perform leak detection, leak location, batch tracking (liquid lines), pig tracking, composition tracking, predictive modeling, look ahead modeling, and operator training. Technology
Components
Pipeline networks are composed of several pieces of equipment that operate together to move products from location to location. The main elements of a pipeline system are:
Initial injection station Known also as "supply" or "inlet" station, is the beginning of the system, where the product is injected into the line. Storage facilities, pumps or compressors are usually located at these locations. Compressor/pump stations Pumps for liquid pipelines and compressors for gas pipelines, are located along the line to move the product through the pipeline. The location of these stations is defined by the topography of the terrain, the type of product being transported, or operational conditions of the network. Partial delivery station Known also as "intermediate stations", these facilities allow the pipeline operator to deliver part of the product being transported. Block valve station These are the first line of protection for pipelines. With these valves the operator can isolate any segment of the line for maintenance work or isolate a rupture or leak. Block valve stations are usually located every 20 to 30 mile (48 km), depending on the type of pipeline. Even though it is not a design rule, it is a very usual practice in liquid pipelines. The location of these stations depends exclusively on the nature of the product being transported, the trajectory of the pipeline and/or the operational conditions of the line. Regulator station This is a special type of valve station, where the operator can release some of the pressure from the line. Regulators are usually located at the downhill side of a peak. Final delivery station Known also as "outlet" stations or terminals, this is where the product will be distributed to the consumer.

Объем рынка строительства нефте- и газопроводов значительно вырос до экономического спада в 2008 году. После снижения в 2009 году спрос на расширение и модернизацию трубопроводов увеличился в следующем году по мере роста производства энергии. К 2012 году почти 51 500 км североамериканских трубопроводов находились в стадии планирования или строительства. Когда пропускная способность трубопроводов ограничена, дополнительные варианты транспортировки нефтепродуктов могут включать использование веществ, снижающих трение, или транспортировку продукции грузовиками или по железной дороге.

Bars in the Veltins Arena, a major football ground in Gelsenkirchen, Germany, are interconnected by a long beer pipeline. In Randers city in Denmark, the so called Thor Beer pipeline was operated. Originally, copper pipes ran directly from the brewery, but when the brewery moved out of the city in the 1990s, Thor Beer replaced it with a giant tank. A three kilometer beer pipeline was completed in Bruges, Belgium in September 2016 to reduce truck traffic on the city streets. Brine
The village of Hallstatt in Austria, which is known for its long history of salt mining, claims to contain "the oldest industrial pipeline in the world", dating back to 1595. It was constructed from 13,000 hollowed out tree trunks to transport brine from Hallstatt to Ebensee. Milk
Between 1978 and 1994, a 15 km milk pipeline ran between the Dutch island of Ameland and Holwerd on the mainland, of which 8 km was beneath the Wadden Sea. Every day, 30,000 litres of milk produced on the island were transported to be processed on the mainland. In 1994, the pipeline was abandoned. Marine pipelines
In places, a pipeline may have to cross water expanses, such as small seas, straits and rivers. In many instances, they lie entirely on the seabed. These pipelines are referred to as "marine" pipelines (also, "submarine" or "offshore" pipelines). They are used primarily to carry oil or gas, but transportation of water is also important. The former is an intrafield pipeline, in the sense that it is used to connect subsea wellheads, manifolds and the platform within a particular development field. The latter, sometimes referred to as an "export pipeline", is used to bring the resource to shore. Russia has "Pipeline Troops" as part of the Rear Services, who are trained to build and repair pipelines. Russia is the only country to have Pipeline Troops. The U. S. government, mainly through the EPA, the FERC and others, reviews proposed pipeline projects in order to comply with the Clean Water Act, the National Environmental Policy Act, other laws and, in some cases, municipal laws. The Biden administration has sought to permit the respective states and tribal groups to appraise and potentially block the proposed projects. Operation
Field devices are instrumentation, data gathering units and communication systems. The field instrumentation includes flow, pressure, and temperature gauges/transmitters, and other devices to measure the relevant data required. These instruments are installed along the pipeline on some specific locations, such as injection or delivery stations, pump stations (liquid pipelines) or compressor stations (gas pipelines), and block valve stations. The information measured by these field instruments is then gathered in local remote terminal units (RTU) that transfer the field data to a central location in real time using communication systems, such as satellite channels, microwave links, or cellular phone connections. Pipelines are controlled and operated remotely, from what is usually known as the "Main Control Room". In this center, all the data related to field measurement is consolidated in one central database. The data is received from multiple RTUs along the pipeline. It is common to find RTUs installed at every station along the pipeline. The SCADA system at the Main Control Room receives all the field data and presents it to the pipeline operator through a set of screens or Human Machine Interface, showing the operational conditions of the pipeline. The operator can monitor the hydraulic conditions of the line, as well as send operational commands (open/close valves, turn on/off compressors or pumps, change setpoints, etc.) through the SCADA system to the field. To optimize and secure the operation of these assets, some pipeline companies are using what is called "Advanced Pipeline Applications", which are software tools installed on top of the SCADA system, that provide extended functionality to perform leak detection, leak location, batch tracking (liquid lines), pig tracking, composition tracking, predictive modeling, look ahead modeling, and operator training. Technology
Components
Pipeline networks are composed of several pieces of equipment that operate together to move products from location to location. The main elements of a pipeline system are:
Initial injection station Known also as "supply" or "inlet" station, is the beginning of the system, where the product is injected into the line. Storage facilities, pumps or compressors are usually located at these locations. Compressor/pump stations Pumps for liquid pipelines and compressors for gas pipelines, are located along the line to move the product through the pipeline. The location of these stations is defined by the topography of the terrain, the type of product being transported, or operational conditions of the network. Partial delivery station Known also as "intermediate stations", these facilities allow the pipeline operator to deliver part of the product being transported. Block valve station These are the first line of protection for pipelines. With these valves the operator can isolate any segment of the line for maintenance work or isolate a rupture or leak. Block valve stations are usually located every 20 to 30 mile (48 km), depending on the type of pipeline. Even though it is not a design rule, it is a very usual practice in liquid pipelines. The location of these stations depends exclusively on the nature of the product being transported, the trajectory of the pipeline and/or the operational conditions of the line. Regulator station This is a special type of valve station, where the operator can release some of the pressure from the line. Regulators are usually located at the downhill side of a peak. Final delivery station Known also as "outlet" stations or terminals, this is where the product will be distributed to the consumer. It could be a tank terminal for liquid pipelines or a connection to a distribution network for gas pipelines. Leak detection systems
Since oil and gas pipelines are an important asset of the economic development of almost any country, it has been required either by government regulations or internal policies to ensure the safety of the assets, and the population and environment where these pipelines run. Pipeline companies face government regulation, environmental constraints and social situations. Government regulations may define minimum staff to run the operation, operator training requirements, pipeline facilities, technology and applications required to ensure operational safety. For example, in the State of Washington it is mandatory for pipeline operators to be able to detect and locate leaks of 8 percent of maximum flow within fifteen minutes or less. Social factors also affect the operation of pipelines. Product theft is sometimes also a problem for pipeline companies. In this case, the detection levels should be under two percent of maximum flow, with a high expectation for location accuracy. Various technologies and strategies have been implemented for monitoring pipelines, from physically walking the lines to satellite surveillance. The most common technology to protect pipelines from occasional leaks is Computational Pipeline Monitoring or CPM. CPM takes information from the field related to pressures, flows, and temperatures to estimate the hydraulic behavior of the product being transported. Once the estimation is completed, the results are compared to other field references to detect the presence of an anomaly or unexpected situation, which may be related to a leak. The American Petroleum Institute has published several articles related to the performance of CPM in liquids pipelines. The API Publications are:
RAM 1130 – Computational pipeline monitoring for liquids pipelines
API 1149 – Pipeline variable uncertainties & their effects on leak detectability
Where a pipeline containing passes under a road or railway, it is usually enclosed in a protective casing. This casing is vented to the atmosphere to prevent the build up of flammable gases or corrosive substances, and to allow the air inside the casing to be sampled to detect leaks. The casing vent, a pipe protruding from the ground, often doubles as a warning marker called a casing vent marker''.

A pipeline is a system of pipes for long distance transportation of a liquid or gas, typically to a market area for consumption. The latest data from 2014 gives a total of slightly less than of pipeline in 120 countries around the world. The United States had 65%, Russia had 8%, and Canada had 3%, thus 76% of all pipeline were in these three countries. Pipeline and Gas Journal'''s worldwide survey figures indicate that of pipelines are planned and under construction. Of these, represent projects in the planning and design phase; reflect pipelines in various stages of construction. Liquids and gases are transported in pipelines, and any chemically stable substance can be sent through a pipeline. Pipelines exist for the transport of crude and refined petroleum, fuels – such as oil, natural gas and biofuels – and other fluids including sewage, slurry, water, beer, hot water or steam for shorter distances. Pipelines are useful for transporting water for drinking or irrigation over long distances when it needs to move over hills, or where canals or channels are poor choices due to considerations of evaporation, pollution, or environmental impact. Oil pipelines are made from steel or plastic tubes which are usually buried. The oil is moved through the pipelines by pump stations along the pipeline. Natural gas (and similar gaseous fuels) are pressurized into liquids known as natural gas liquids (NGLs). Natural gas pipelines are constructed of carbon steel. Hydrogen pipeline transport is the transportation of hydrogen through a pipe. Pipelines are one of the safest ways of transporting materials as compared to road or rail, and hence in war, pipelines are often the target of military attacks. Oil and natural gas
It is well documented when the first crude oil pipeline was built. Credit for the development of pipeline transport belongs indisputably to the Oil Transport Association, which first constructed a wrought iron pipeline over a 6 mile (10 km) track from an oil field in Pennsylvania to a railroad station in Oil Creek, in the 1860s. Pipelines are generally the most economical way to transport large quantities of oil, refined oil products or natural gas over land. For example, in 2014, pipeline transport of crude oil cost about $5 per barrel, while rail transport cost about $10 to $15 per barrel. Trucking has even higher costs due to the additional labor required; employment on completed pipelines represents only "1% of that of the trucking industry.". In the United States, 70% of crude oil and petroleum products are shipped by pipeline. (23% are by ship, 4% by truck, and 3% by rail) In Canada for natural gas and petroleum products, 97% are shipped by pipeline. As more North American pipelines are built, even more exports of LNG, propane, butane, and other natural gas products occur on all three US coasts. To give insight, North Dakota Bakken region's oil production has grown by 600% from 2007 to 2015. North Dakota oil companies are shipping huge amounts of oil by tanker rail car as they can direct the oil to the market that gives the best price, and rail cars can be used to avoid a congested oil pipeline to get the oil to a different pipeline in order to get the oil to market faster or to a different less busy oil refinery. However, pipelines provide a cheaper means to transport by volume. Enbridge in Canada is applying to reverse an oil pipeline going from east to west (Line 9) and expanding it and using it to ship western Canadian bitumen oil eastward. From a presently rated 250,000 barrels equivalent per day pipeline, it will be expanded to between 1.0 and 1.3 million barrels per day. It will bring western oil to refineries in Ontario, Michigan, Ohio, Pennsylvania, Quebec and New York by early 2014. New Brunswick will also refine some of this western Canadian crude and export some crude and refined oil to Europe from its deep water oil ULCC loading port. Although pipelines can be built under the sea, that process is economically and technically demanding, so the majority of oil at sea is transported by tanker ships. Similarly, it is often more economically feasible to transport natural gas in the form of LNG, however the break even point between LNG and pipelines would depend on the volume of natural gas and the distance it travels. Growth of market
The market size for oil and gas pipeline construction experienced tremendous growth prior to the economic downturn in 2008. After faltering in 2009, demand for pipeline expansion and updating increased the following year as energy production grew. By 2012, almost 32,000 miles (51500 km) of North American pipeline were being planned or under construction. When pipelines are constrained, additional pipeline product transportation options may include the use of drag reducing agents, or by transporting product via truck or rail. Construction and operation
Oil pipelines are made from steel or plastic tubes with inner diameter typically from Most pipelines are typically buried at a depth of about To protect pipes from impact, abrasion, and corrosion, a variety of methods are used. These can include wood lagging (wood slats), concrete coating, rockshield, high density polyethylene, imported sand padding, sacrificial cathodes and padding machines. Crude oil contains varying amounts of paraffin wax and in colder climates wax buildup may occur within a pipeline. Often these pipelines are inspected and cleaned using pigging, the practice of using devices known as "pigs" to perform various maintenance operations on a pipeline. The devices are also known as "scrapers" or "Go devils". "Smart pigs" (also known as "intelligent" or "intelligence" pigs) are used to detect anomalies in the pipe such as dents, metal loss caused by corrosion, cracking or other mechanical damage. These devices are launched from pig launcher stations and travel through the pipeline to be received at any other station down stream, either cleaning wax deposits and material that may have accumulated inside the line or inspecting and recording the condition of the line. For natural gas, pipelines are constructed of carbon steel and vary in size from in diameter, depending on the type of pipeline. The gas is pressurized by compressor stations and is odorless unless mixed with a mercaptan odorant where required by a regulating authority. Ammonia
A major ammonia pipeline is the Ukrainian Transammiak line connecting the TogliattiAzot facility in Russia to the exporting Black Sea port of Odesa. Alcohol fuels
Pipelines have been used for transportation of ethanol in Brazil, and there are several ethanol pipeline projects in Brazil and the United States. The main problems related to the transport of ethanol by pipeline are its corrosive nature and tendency to absorb water and impurities in pipelines, which are not problems with oil and natural gas. Insufficient volumes and cost effectiveness are other considerations limiting construction of ethanol pipelines. In the US minimal amounts of ethanol are transported by pipeline. Most ethanol is shipped by rail, the main alternatives being truck and barge. Delivering ethanol by pipeline is the most desirable option, but ethanol's affinity for water and solvent properties require the use of a dedicated pipeline, or significant cleanup of existing pipelines. Coal and ore
Slurry pipelines are sometimes used to transport coal or ore from mines. The material to be transported is closely mixed with water before being introduced to the pipeline; at the far end, the material must be dried. One example is a slurry pipeline which is planned to transport iron ore from the Minas Rio mine (producing 26.5 million tonnes per year) to the Port of Açu in Brazil. An existing example is the Savage River Slurry pipeline in Tasmania, Australia, possibly the world's first when it was built in 1967. It includes a bridge span at above the Savage River. Hydrogen
Hydrogen pipeline transport is a transportation of hydrogen through a pipe as part of the hydrogen infrastructure. Hydrogen pipeline transport is used to connect the point of hydrogen production or delivery of hydrogen with the point of demand, with transport costs similar to CNG, the technology is proven. Most hydrogen is produced at the place of demand with every 50 to 100 mile (161 km) an industrial production facility. The 1938 Rhine Ruhr hydrogen pipeline is still in operation. as of 2004, there are 900 mile (1448 km) of low pressure hydrogen pipelines in the US and 930 mile (1497 km) in Europe. Water
Two millennia ago, the ancient Romans made use of large aqueducts to transport water from higher elevations by building the aqueducts in graduated segments that allowed gravity to push the water along until it reached its destination. Hundreds of these were built throughout Europe and elsewhere, and along with flour mills were considered the lifeline of the Roman Empire. The ancient Chinese also made use of channels and pipe systems for public works. The famous Han dynasty court eunuch Zhang Rang (d. 189 AD) once ordered the engineer Bi Lan to construct a series of square pallet chain pumps outside the capital city of Luoyang. These chain pumps serviced the imperial palaces and living quarters of the capital city as the water lifted by the chain pumps was brought in by a stoneware pipe system. Pipelines are useful for transporting water for drinking or irrigation over long distances when it needs to move over hills, or where canals or channels are poor choices due to considerations of evaporation, pollution, or environmental impact. The Goldfields Water Supply Scheme in Western Australia using 750 mm (30 inch) pipe and completed in 1903 was the largest water supply scheme of its time. Examples of significant water pipelines in South Australia are the Morgan Whyalla pipeline (completed 1944) and Mannum Adelaide pipeline (completed 1955) pipelines, both part of the larger Snowy Mountains scheme. There are two Los Angeles, California aqueducts, the Owens Valley aqueduct (completed 1913) and the Second Los Angeles Aqueduct (completed 1970) which also include extensive use of pipelines. The Great Manmade River of Libya supplies of water each day to Tripoli, Benghazi, Sirte, and several other cities in Libya. The pipeline is over long, and is connected to wells tapping an aquifer over underground. Other systems
District heating
District heating or teleheating systems consist of a network of insulated feed and return pipes which transport heated water, pressurized hot water, or sometimes steam to the customer. While steam is hottest and may be used in industrial processes due to its higher temperature, it is less efficient to produce and transport due to greater heat losses. Heat transfer oils are generally not used for economic and ecological reasons. The typical annual loss of thermal energy through distribution is around 10%, as seen in Norway's district heating network. District heating pipelines are normally installed underground, with some exceptions. Within the system, heat storage may be installed to even out peak load demands. Heat is transferred into the central heating of the dwellings through heat exchangers at heat substations, without mixing of the fluids in either system. Beer

The 1938 Rhine Ruhr hydrogen pipeline is still in operation. as of 2004, there are 900 mile (1448 km) of low pressure hydrogen pipelines in the US and 930 mile (1497 km) in Europe. Water
Two millennia ago, the ancient Romans made use of large aqueducts to transport water from higher elevations by building the aqueducts in graduated segments that allowed gravity to push the water along until it reached its destination. Hundreds of these were built throughout Europe and elsewhere, and along with flour mills were considered the lifeline of the Roman Empire. The ancient Chinese also made use of channels and pipe systems for public works. The famous Han dynasty court eunuch Zhang Rang (d. 189 AD) once ordered the engineer Bi Lan to construct a series of square pallet chain pumps outside the capital city of Luoyang. These chain pumps serviced the imperial palaces and living quarters of the capital city as the water lifted by the chain pumps was brought in by a stoneware pipe system. Pipelines are useful for transporting water for drinking or irrigation over long distances when it needs to move over hills, or where canals or channels are poor choices due to considerations of evaporation, pollution, or environmental impact. The Goldfields Water Supply Scheme in Western Australia using 750 mm (30 inch) pipe and completed in 1903 was the largest water supply scheme of its time. Examples of significant water pipelines in South Australia are the Morgan Whyalla pipeline (completed 1944) and Mannum Adelaide pipeline (completed 1955) pipelines, both part of the larger Snowy Mountains scheme. There are two Los Angeles, California aqueducts, the Owens Valley aqueduct (completed 1913) and the Second Los Angeles Aqueduct (completed 1970) which also include extensive use of pipelines. The Great Manmade River of Libya supplies of water each day to Tripoli, Benghazi, Sirte, and several other cities in Libya. The pipeline is over long, and is connected to wells tapping an aquifer over underground. Other systems
District heating
District heating or teleheating systems consist of a network of insulated feed and return pipes which transport heated water, pressurized hot water, or sometimes steam to the customer. While steam is hottest and may be used in industrial processes due to its higher temperature, it is less efficient to produce and transport due to greater heat losses. Heat transfer oils are generally not used for economic and ecological reasons. The typical annual loss of thermal energy through distribution is around 10%, as seen in Norway's district heating network. District heating pipelines are normally installed underground, with some exceptions. Within the system, heat storage may be installed to even out peak load demands. Heat is transferred into the central heating of the dwellings through heat exchangers at heat substations, without mixing of the fluids in either system. Beer
Bars in the Veltins Arena, a major football ground in Gelsenkirchen, Germany, are interconnected by a long beer pipeline. In Randers city in Denmark, the so called Thor Beer pipeline was operated. Originally, copper pipes ran directly from the brewery, but when the brewery moved out of the city in the 1990s, Thor Beer replaced it with a giant tank. A three kilometer beer pipeline was completed in Bruges, Belgium in September 2016 to reduce truck traffic on the city streets. Brine
The village of Hallstatt in Austria, which is known for its long history of salt mining, claims to contain "the oldest industrial pipeline in the world", dating back to 1595. It was constructed from 13,000 hollowed out tree trunks to transport brine from Hallstatt to Ebensee. Milk
Between 1978 and 1994, a 15 km milk pipeline ran between the Dutch island of Ameland and Holwerd on the mainland, of which 8 km was beneath the Wadden Sea. Every day, 30,000 litres of milk produced on the island were transported to be processed on the mainland. In 1994, the pipeline was abandoned. Marine pipelines
In places, a pipeline may have to cross water expanses, such as small seas, straits and rivers. In many instances, they lie entirely on the seabed. These pipelines are referred to as "marine" pipelines (also, "submarine" or "offshore" pipelines). They are used primarily to carry oil or gas, but transportation of water is also important. The former is an intrafield pipeline, in the sense that it is used to connect subsea wellheads, manifolds and the platform within a particular development field. The latter, sometimes referred to as an "export pipeline", is used to bring the resource to shore. Russia has "Pipeline Troops" as part of the Rear Services, who are trained to build and repair pipelines. Russia is the only country to have Pipeline Troops. The U. S. government, mainly through the EPA, the FERC and others, reviews proposed pipeline projects in order to comply with the Clean Water Act, the National Environmental Policy Act, other laws and, in some cases, municipal laws. The Biden administration has sought to permit the respective states and tribal groups to appraise and potentially block the proposed projects. Operation
Field devices are instrumentation, data gathering units and communication systems. The field instrumentation includes flow, pressure, and temperature gauges/transmitters, and other devices to measure the relevant data required. These instruments are installed along the pipeline on some specific locations, such as injection or delivery stations, pump stations (liquid pipelines) or compressor stations (gas pipelines), and block valve stations. The information measured by these field instruments is then gathered in local remote terminal units (RTU) that transfer the field data to a central location in real time using communication systems, such as satellite channels, microwave links, or cellular phone connections. Pipelines are controlled and operated remotely, from what is usually known as the "Main Control Room". In this center, all the data related to field measurement is consolidated in one central database. The data is received from multiple RTUs along the pipeline. It is common to find RTUs installed at every station along the pipeline. The SCADA system at the Main Control Room receives all the field data and presents it to the pipeline operator through a set of screens or Human Machine Interface, showing the operational conditions of the pipeline. The operator can monitor the hydraulic conditions of the line, as well as send operational commands (open/close valves, turn on/off compressors or pumps, change setpoints, etc.) through the SCADA system to the field. To optimize and secure the operation of these assets, some pipeline companies are using what is called "Advanced Pipeline Applications", which are software tools installed on top of the SCADA system, that provide extended functionality to perform leak detection, leak location, batch tracking (liquid lines), pig tracking, composition tracking, predictive modeling, look ahead modeling, and operator training. Technology
Components
Pipeline networks are composed of several pieces of equipment that operate together to move products from location to location. The main elements of a pipeline system are:
Initial injection station Known also as "supply" or "inlet" station, is the beginning of the system, where the product is injected into the line. Storage facilities, pumps or compressors are usually located at these locations. Compressor/pump stations Pumps for liquid pipelines and compressors for gas pipelines, are located along the line to move the product through the pipeline. The location of these stations is defined by the topography of the terrain, the type of product being transported, or operational conditions of the network. Partial delivery station Known also as "intermediate stations", these facilities allow the pipeline operator to deliver part of the product being transported. Block valve station These are the first line of protection for pipelines. With these valves the operator can isolate any segment of the line for maintenance work or isolate a rupture or leak. Block valve stations are usually located every 20 to 30 mile (48 km), depending on the type of pipeline. Even though it is not a design rule, it is a very usual practice in liquid pipelines. The location of these stations depends exclusively on the nature of the product being transported, the trajectory of the pipeline and/or the operational conditions of the line. Regulator station This is a special type of valve station, where the operator can release some of the pressure from the line. Regulators are usually located at the downhill side of a peak. Final delivery station Known also as "outlet" stations or terminals, this is where the product will be distributed to the consumer. It could be a tank terminal for liquid pipelines or a connection to a distribution network for gas pipelines. Leak detection systems
Since oil and gas pipelines are an important asset of the economic development of almost any country, it has been required either by government regulations or internal policies to ensure the safety of the assets, and the population and environment where these pipelines run. Pipeline companies face government regulation, environmental constraints and social situations. Government regulations may define minimum staff to run the operation, operator training requirements, pipeline facilities, technology and applications required to ensure operational safety. For example, in the State of Washington it is mandatory for pipeline operators to be able to detect and locate leaks of 8 percent of maximum flow within fifteen minutes or less. Social factors also affect the operation of pipelines. Product theft is sometimes also a problem for pipeline companies. In this case, the detection levels should be under two percent of maximum flow, with a high expectation for location accuracy. Various technologies and strategies have been implemented for monitoring pipelines, from physically walking the lines to satellite surveillance. The most common technology to protect pipelines from occasional leaks is Computational Pipeline Monitoring or CPM. CPM takes information from the field related to pressures, flows, and temperatures to estimate the hydraulic behavior of the product being transported. Once the estimation is completed, the results are compared to other field references to detect the presence of an anomaly or unexpected situation, which may be related to a leak. The American Petroleum Institute has published several articles related to the performance of CPM in liquids pipelines. The API Publications are:
RAM 1130 – Computational pipeline monitoring for liquids pipelines
API 1149 – Pipeline variable uncertainties & their effects on leak detectability
Where a pipeline containing passes under a road or railway, it is usually enclosed in a protective casing. This casing is vented to the atmosphere to prevent the build up of flammable gases or corrosive substances, and to allow the air inside the casing to be sampled to detect leaks. The casing vent, a pipe protruding from the ground, often doubles as a warning marker called a casing vent marker''.
Трубопроводы использовались для транспортировки этанола в Бразилии, и существует несколько проектов этанольных трубопроводов в Бразилии и Соединенных Штатах. Основные проблемы, связанные с транспортировкой этанола по трубопроводу, – это его коррозионные свойства и тенденция к поглощению воды и примесей в трубопроводах, что не является проблемой для нефти и природного газа. Недостаточные объемы и экономическая эффективность – другие факторы, ограничивающие строительство этанольных трубопроводов. В США минимальные объемы этанола транспортируются по трубопроводам. Большая часть этанола перевозится по железной дороге, основными альтернативами являются автомобильный и баржевый транспорт. Доставка этанола по трубопроводу является наиболее предпочтительным вариантом, но склонность этанола к воде и растворяющие свойства требуют использования выделенного трубопровода или значительной очистки существующих трубопроводов.

A pipeline is a system of pipes for long distance transportation of a liquid or gas, typically to a market area for consumption. The latest data from 2014 gives a total of slightly less than of pipeline in 120 countries around the world. The United States had 65%, Russia had 8%, and Canada had 3%, thus 76% of all pipeline were in these three countries. Pipeline and Gas Journal'''s worldwide survey figures indicate that of pipelines are planned and under construction. Of these, represent projects in the planning and design phase; reflect pipelines in various stages of construction. Liquids and gases are transported in pipelines, and any chemically stable substance can be sent through a pipeline. Pipelines exist for the transport of crude and refined petroleum, fuels – such as oil, natural gas and biofuels – and other fluids including sewage, slurry, water, beer, hot water or steam for shorter distances. Pipelines are useful for transporting water for drinking or irrigation over long distances when it needs to move over hills, or where canals or channels are poor choices due to considerations of evaporation, pollution, or environmental impact. Oil pipelines are made from steel or plastic tubes which are usually buried. The oil is moved through the pipelines by pump stations along the pipeline. Natural gas (and similar gaseous fuels) are pressurized into liquids known as natural gas liquids (NGLs). Natural gas pipelines are constructed of carbon steel. Hydrogen pipeline transport is the transportation of hydrogen through a pipe. Pipelines are one of the safest ways of transporting materials as compared to road or rail, and hence in war, pipelines are often the target of military attacks. Oil and natural gas
It is well documented when the first crude oil pipeline was built. Credit for the development of pipeline transport belongs indisputably to the Oil Transport Association, which first constructed a wrought iron pipeline over a 6 mile (10 km) track from an oil field in Pennsylvania to a railroad station in Oil Creek, in the 1860s. Pipelines are generally the most economical way to transport large quantities of oil, refined oil products or natural gas over land. For example, in 2014, pipeline transport of crude oil cost about $5 per barrel, while rail transport cost about $10 to $15 per barrel. Trucking has even higher costs due to the additional labor required; employment on completed pipelines represents only "1% of that of the trucking industry.". In the United States, 70% of crude oil and petroleum products are shipped by pipeline. (23% are by ship, 4% by truck, and 3% by rail) In Canada for natural gas and petroleum products, 97% are shipped by pipeline. As more North American pipelines are built, even more exports of LNG, propane, butane, and other natural gas products occur on all three US coasts. To give insight, North Dakota Bakken region's oil production has grown by 600% from 2007 to 2015. North Dakota oil companies are shipping huge amounts of oil by tanker rail car as they can direct the oil to the market that gives the best price, and rail cars can be used to avoid a congested oil pipeline to get the oil to a different pipeline in order to get the oil to market faster or to a different less busy oil refinery. However, pipelines provide a cheaper means to transport by volume. Enbridge in Canada is applying to reverse an oil pipeline going from east to west (Line 9) and expanding it and using it to ship western Canadian bitumen oil eastward. From a presently rated 250,000 barrels equivalent per day pipeline, it will be expanded to between 1.0 and 1.3 million barrels per day. It will bring western oil to refineries in Ontario, Michigan, Ohio, Pennsylvania, Quebec and New York by early 2014. New Brunswick will also refine some of this western Canadian crude and export some crude and refined oil to Europe from its deep water oil ULCC loading port. Although pipelines can be built under the sea, that process is economically and technically demanding, so the majority of oil at sea is transported by tanker ships. Similarly, it is often more economically feasible to transport natural gas in the form of LNG, however the break even point between LNG and pipelines would depend on the volume of natural gas and the distance it travels. Growth of market
The market size for oil and gas pipeline construction experienced tremendous growth prior to the economic downturn in 2008. After faltering in 2009, demand for pipeline expansion and updating increased the following year as energy production grew. By 2012, almost 32,000 miles (51500 km) of North American pipeline were being planned or under construction. When pipelines are constrained, additional pipeline product transportation options may include the use of drag reducing agents, or by transporting product via truck or rail. Construction and operation
Oil pipelines are made from steel or plastic tubes with inner diameter typically from Most pipelines are typically buried at a depth of about To protect pipes from impact, abrasion, and corrosion, a variety of methods are used. These can include wood lagging (wood slats), concrete coating, rockshield, high density polyethylene, imported sand padding, sacrificial cathodes and padding machines. Crude oil contains varying amounts of paraffin wax and in colder climates wax buildup may occur within a pipeline. Often these pipelines are inspected and cleaned using pigging, the practice of using devices known as "pigs" to perform various maintenance operations on a pipeline. The devices are also known as "scrapers" or "Go devils". "Smart pigs" (also known as "intelligent" or "intelligence" pigs) are used to detect anomalies in the pipe such as dents, metal loss caused by corrosion, cracking or other mechanical damage. These devices are launched from pig launcher stations and travel through the pipeline to be received at any other station down stream, either cleaning wax deposits and material that may have accumulated inside the line or inspecting and recording the condition of the line. For natural gas, pipelines are constructed of carbon steel and vary in size from in diameter, depending on the type of pipeline. The gas is pressurized by compressor stations and is odorless unless mixed with a mercaptan odorant where required by a regulating authority. Ammonia
A major ammonia pipeline is the Ukrainian Transammiak line connecting the TogliattiAzot facility in Russia to the exporting Black Sea port of Odesa. Alcohol fuels
Pipelines have been used for transportation of ethanol in Brazil, and there are several ethanol pipeline projects in Brazil and the United States. The main problems related to the transport of ethanol by pipeline are its corrosive nature and tendency to absorb water and impurities in pipelines, which are not problems with oil and natural gas. Insufficient volumes and cost effectiveness are other considerations limiting construction of ethanol pipelines. In the US minimal amounts of ethanol are transported by pipeline. Most ethanol is shipped by rail, the main alternatives being truck and barge. Delivering ethanol by pipeline is the most desirable option, but ethanol's affinity for water and solvent properties require the use of a dedicated pipeline, or significant cleanup of existing pipelines. Coal and ore
Slurry pipelines are sometimes used to transport coal or ore from mines. The material to be transported is closely mixed with water before being introduced to the pipeline; at the far end, the material must be dried. One example is a slurry pipeline which is planned to transport iron ore from the Minas Rio mine (producing 26.5 million tonnes per year) to the Port of Açu in Brazil. An existing example is the Savage River Slurry pipeline in Tasmania, Australia, possibly the world's first when it was built in 1967. It includes a bridge span at above the Savage River. Hydrogen
Hydrogen pipeline transport is a transportation of hydrogen through a pipe as part of the hydrogen infrastructure. Hydrogen pipeline transport is used to connect the point of hydrogen production or delivery of hydrogen with the point of demand, with transport costs similar to CNG, the technology is proven. Most hydrogen is produced at the place of demand with every 50 to 100 mile (161 km) an industrial production facility. The 1938 Rhine Ruhr hydrogen pipeline is still in operation. as of 2004, there are 900 mile (1448 km) of low pressure hydrogen pipelines in the US and 930 mile (1497 km) in Europe. Water

The ancient Chinese also made use of channels and pipe systems for public works.

Pipelines are useful for transporting water for drinking or irrigation over long distances when it needs to move over hills, or where canals or channels are poor choices due to considerations of evaporation, pollution, or environmental impact. The Goldfields Water Supply Scheme in Western Australia using 750 mm (30 inch) pipe and completed in 1903 was the largest water supply scheme of its time. Examples of significant water pipelines in South Australia are the Morgan Whyalla pipeline (completed 1944) and Mannum Adelaide pipeline (completed 1955) pipelines, both part of the larger Snowy Mountains scheme. There are two Los Angeles, California aqueducts, the Owens Valley aqueduct (completed 1913) and the Second Los Angeles Aqueduct (completed 1970) which also include extensive use of pipelines. The Great Manmade River of Libya supplies of water each day to Tripoli, Benghazi, Sirte, and several other cities in Libya.

These devices are launched from pig launcher stations and travel through the pipeline to be received at any other station down stream, either cleaning wax deposits and material that may have accumulated inside the line or inspecting and recording the condition of the line. For natural gas, pipelines are constructed of carbon steel and vary in size from in diameter, depending on the type of pipeline. The gas is pressurized by compressor stations and is odorless unless mixed with a mercaptan odorant where required by a regulating authority. Ammonia
A major ammonia pipeline is the Ukrainian Transammiak line connecting the TogliattiAzot facility in Russia to the exporting Black Sea port of Odesa. Alcohol fuels
Pipelines have been used for transportation of ethanol in Brazil, and there are several ethanol pipeline projects in Brazil and the United States. The main problems related to the transport of ethanol by pipeline are its corrosive nature and tendency to absorb water and impurities in pipelines, which are not problems with oil and natural gas. Insufficient volumes and cost effectiveness are other considerations limiting construction of ethanol pipelines. In the US minimal amounts of ethanol are transported by pipeline. Most ethanol is shipped by rail, the main alternatives being truck and barge. Delivering ethanol by pipeline is the most desirable option, but ethanol's affinity for water and solvent properties require the use of a dedicated pipeline, or significant cleanup of existing pipelines. Coal and ore
Slurry pipelines are sometimes used to transport coal or ore from mines. The material to be transported is closely mixed with water before being introduced to the pipeline; at the far end, the material must be dried. One example is a slurry pipeline which is planned to transport iron ore from the Minas Rio mine (producing 26.5 million tonnes per year) to the Port of Açu in Brazil. An existing example is the Savage River Slurry pipeline in Tasmania, Australia, possibly the world's first when it was built in 1967. It includes a bridge span at above the Savage River. Hydrogen
Hydrogen pipeline transport is a transportation of hydrogen through a pipe as part of the hydrogen infrastructure. Hydrogen pipeline transport is used to connect the point of hydrogen production or delivery of hydrogen with the point of demand, with transport costs similar to CNG, the technology is proven. Most hydrogen is produced at the place of demand with every 50 to 100 mile (161 km) an industrial production facility. The 1938 Rhine Ruhr hydrogen pipeline is still in operation. as of 2004, there are 900 mile (1448 km) of low pressure hydrogen pipelines in the US and 930 mile (1497 km) in Europe. Water
Two millennia ago, the ancient Romans made use of large aqueducts to transport water from higher elevations by building the aqueducts in graduated segments that allowed gravity to push the water along until it reached its destination. Hundreds of these were built throughout Europe and elsewhere, and along with flour mills were considered the lifeline of the Roman Empire. The ancient Chinese also made use of channels and pipe systems for public works. The famous Han dynasty court eunuch Zhang Rang (d. 189 AD) once ordered the engineer Bi Lan to construct a series of square pallet chain pumps outside the capital city of Luoyang. These chain pumps serviced the imperial palaces and living quarters of the capital city as the water lifted by the chain pumps was brought in by a stoneware pipe system. Pipelines are useful for transporting water for drinking or irrigation over long distances when it needs to move over hills, or where canals or channels are poor choices due to considerations of evaporation, pollution, or environmental impact. The Goldfields Water Supply Scheme in Western Australia using 750 mm (30 inch) pipe and completed in 1903 was the largest water supply scheme of its time. Examples of significant water pipelines in South Australia are the Morgan Whyalla pipeline (completed 1944) and Mannum Adelaide pipeline (completed 1955) pipelines, both part of the larger Snowy Mountains scheme. There are two Los Angeles, California aqueducts, the Owens Valley aqueduct (completed 1913) and the Second Los Angeles Aqueduct (completed 1970) which also include extensive use of pipelines. The Great Manmade River of Libya supplies of water each day to Tripoli, Benghazi, Sirte, and several other cities in Libya. The pipeline is over long, and is connected to wells tapping an aquifer over underground. Other systems
District heating
District heating or teleheating systems consist of a network of insulated feed and return pipes which transport heated water, pressurized hot water, or sometimes steam to the customer. While steam is hottest and may be used in industrial processes due to its higher temperature, it is less efficient to produce and transport due to greater heat losses. Heat transfer oils are generally not used for economic and ecological reasons. The typical annual loss of thermal energy through distribution is around 10%, as seen in Norway's district heating network. District heating pipelines are normally installed underground, with some exceptions. Within the system, heat storage may be installed to even out peak load demands. Heat is transferred into the central heating of the dwellings through heat exchangers at heat substations, without mixing of the fluids in either system. Beer
Bars in the Veltins Arena, a major football ground in Gelsenkirchen, Germany, are interconnected by a long beer pipeline. In Randers city in Denmark, the so called Thor Beer pipeline was operated. Originally, copper pipes ran directly from the brewery, but when the brewery moved out of the city in the 1990s, Thor Beer replaced it with a giant tank. A three kilometer beer pipeline was completed in Bruges, Belgium in September 2016 to reduce truck traffic on the city streets. Brine
The village of Hallstatt in Austria, which is known for its long history of salt mining, claims to contain "the oldest industrial pipeline in the world", dating back to 1595. It was constructed from 13,000 hollowed out tree trunks to transport brine from Hallstatt to Ebensee. Milk
Between 1978 and 1994, a 15 km milk pipeline ran between the Dutch island of Ameland and Holwerd on the mainland, of which 8 km was beneath the Wadden Sea. Every day, 30,000 litres of milk produced on the island were transported to be processed on the mainland. In 1994, the pipeline was abandoned. Marine pipelines
In places, a pipeline may have to cross water expanses, such as small seas, straits and rivers. In many instances, they lie entirely on the seabed. These pipelines are referred to as "marine" pipelines (also, "submarine" or "offshore" pipelines). They are used primarily to carry oil or gas, but transportation of water is also important. The former is an intrafield pipeline, in the sense that it is used to connect subsea wellheads, manifolds and the platform within a particular development field. The latter, sometimes referred to as an "export pipeline", is used to bring the resource to shore. Russia has "Pipeline Troops" as part of the Rear Services, who are trained to build and repair pipelines. Russia is the only country to have Pipeline Troops. The U. S. government, mainly through the EPA, the FERC and others, reviews proposed pipeline projects in order to comply with the Clean Water Act, the National Environmental Policy Act, other laws and, in some cases, municipal laws. The Biden administration has sought to permit the respective states and tribal groups to appraise and potentially block the proposed projects. Operation
Field devices are instrumentation, data gathering units and communication systems. The field instrumentation includes flow, pressure, and temperature gauges/transmitters, and other devices to measure the relevant data required. These instruments are installed along the pipeline on some specific locations, such as injection or delivery stations, pump stations (liquid pipelines) or compressor stations (gas pipelines), and block valve stations. The information measured by these field instruments is then gathered in local remote terminal units (RTU) that transfer the field data to a central location in real time using communication systems, such as satellite channels, microwave links, or cellular phone connections. Pipelines are controlled and operated remotely, from what is usually known as the "Main Control Room". In this center, all the data related to field measurement is consolidated in one central database. The data is received from multiple RTUs along the pipeline. It is common to find RTUs installed at every station along the pipeline. The SCADA system at the Main Control Room receives all the field data and presents it to the pipeline operator through a set of screens or Human Machine Interface, showing the operational conditions of the pipeline. The operator can monitor the hydraulic conditions of the line, as well as send operational commands (open/close valves, turn on/off compressors or pumps, change setpoints, etc.) through the SCADA system to the field. To optimize and secure the operation of these assets, some pipeline companies are using what is called "Advanced Pipeline Applications", which are software tools installed on top of the SCADA system, that provide extended functionality to perform leak detection, leak location, batch tracking (liquid lines), pig tracking, composition tracking, predictive modeling, look ahead modeling, and operator training. Technology
Components
Pipeline networks are composed of several pieces of equipment that operate together to move products from location to location. The main elements of a pipeline system are:
Initial injection station Known also as "supply" or "inlet" station, is the beginning of the system, where the product is injected into the line. Storage facilities, pumps or compressors are usually located at these locations. Compressor/pump stations Pumps for liquid pipelines and compressors for gas pipelines, are located along the line to move the product through the pipeline. The location of these stations is defined by the topography of the terrain, the type of product being transported, or operational conditions of the network. Partial delivery station Known also as "intermediate stations", these facilities allow the pipeline operator to deliver part of the product being transported. Block valve station These are the first line of protection for pipelines. With these valves the operator can isolate any segment of the line for maintenance work or isolate a rupture or leak. Block valve stations are usually located every 20 to 30 mile (48 km), depending on the type of pipeline. Even though it is not a design rule, it is a very usual practice in liquid pipelines. The location of these stations depends exclusively on the nature of the product being transported, the trajectory of the pipeline and/or the operational conditions of the line. Regulator station This is a special type of valve station, where the operator can release some of the pressure from the line. Regulators are usually located at the downhill side of a peak. Final delivery station Known also as "outlet" stations or terminals, this is where the product will be distributed to the consumer. It could be a tank terminal for liquid pipelines or a connection to a distribution network for gas pipelines. Leak detection systems
Since oil and gas pipelines are an important asset of the economic development of almost any country, it has been required either by government regulations or internal policies to ensure the safety of the assets, and the population and environment where these pipelines run. Pipeline companies face government regulation, environmental constraints and social situations. Government regulations may define minimum staff to run the operation, operator training requirements, pipeline facilities, technology and applications required to ensure operational safety. For example, in the State of Washington it is mandatory for pipeline operators to be able to detect and locate leaks of 8 percent of maximum flow within fifteen minutes or less. Social factors also affect the operation of pipelines. Product theft is sometimes also a problem for pipeline companies. In this case, the detection levels should be under two percent of maximum flow, with a high expectation for location accuracy. Various technologies and strategies have been implemented for monitoring pipelines, from physically walking the lines to satellite surveillance. The most common technology to protect pipelines from occasional leaks is Computational Pipeline Monitoring or CPM. CPM takes information from the field related to pressures, flows, and temperatures to estimate the hydraulic behavior of the product being transported. Once the estimation is completed, the results are compared to other field references to detect the presence of an anomaly or unexpected situation, which may be related to a leak. The American Petroleum Institute has published several articles related to the performance of CPM in liquids pipelines. The API Publications are:
RAM 1130 – Computational pipeline monitoring for liquids pipelines
API 1149 – Pipeline variable uncertainties & their effects on leak detectability
Where a pipeline containing passes under a road or railway, it is usually enclosed in a protective casing. This casing is vented to the atmosphere to prevent the build up of flammable gases or corrosive substances, and to allow the air inside the casing to be sampled to detect leaks. The casing vent, a pipe protruding from the ground, often doubles as a warning marker called a casing vent marker''.

A pipeline is a system of pipes for long distance transportation of a liquid or gas, typically to a market area for consumption. The latest data from 2014 gives a total of slightly less than of pipeline in 120 countries around the world. The United States had 65%, Russia had 8%, and Canada had 3%, thus 76% of all pipeline were in these three countries. Pipeline and Gas Journal'''s worldwide survey figures indicate that of pipelines are planned and under construction. Of these, represent projects in the planning and design phase; reflect pipelines in various stages of construction. Liquids and gases are transported in pipelines, and any chemically stable substance can be sent through a pipeline. Pipelines exist for the transport of crude and refined petroleum, fuels – such as oil, natural gas and biofuels – and other fluids including sewage, slurry, water, beer, hot water or steam for shorter distances. Pipelines are useful for transporting water for drinking or irrigation over long distances when it needs to move over hills, or where canals or channels are poor choices due to considerations of evaporation, pollution, or environmental impact. Oil pipelines are made from steel or plastic tubes which are usually buried. The oil is moved through the pipelines by pump stations along the pipeline. Natural gas (and similar gaseous fuels) are pressurized into liquids known as natural gas liquids (NGLs). Natural gas pipelines are constructed of carbon steel. Hydrogen pipeline transport is the transportation of hydrogen through a pipe. Pipelines are one of the safest ways of transporting materials as compared to road or rail, and hence in war, pipelines are often the target of military attacks. Oil and natural gas
It is well documented when the first crude oil pipeline was built. Credit for the development of pipeline transport belongs indisputably to the Oil Transport Association, which first constructed a wrought iron pipeline over a 6 mile (10 km) track from an oil field in Pennsylvania to a railroad station in Oil Creek, in the 1860s. Pipelines are generally the most economical way to transport large quantities of oil, refined oil products or natural gas over land. For example, in 2014, pipeline transport of crude oil cost about $5 per barrel, while rail transport cost about $10 to $15 per barrel. Trucking has even higher costs due to the additional labor required; employment on completed pipelines represents only "1% of that of the trucking industry.". In the United States, 70% of crude oil and petroleum products are shipped by pipeline. (23% are by ship, 4% by truck, and 3% by rail) In Canada for natural gas and petroleum products, 97% are shipped by pipeline. As more North American pipelines are built, even more exports of LNG, propane, butane, and other natural gas products occur on all three US coasts. To give insight, North Dakota Bakken region's oil production has grown by 600% from 2007 to 2015. North Dakota oil companies are shipping huge amounts of oil by tanker rail car as they can direct the oil to the market that gives the best price, and rail cars can be used to avoid a congested oil pipeline to get the oil to a different pipeline in order to get the oil to market faster or to a different less busy oil refinery. However, pipelines provide a cheaper means to transport by volume. Enbridge in Canada is applying to reverse an oil pipeline going from east to west (Line 9) and expanding it and using it to ship western Canadian bitumen oil eastward. From a presently rated 250,000 barrels equivalent per day pipeline, it will be expanded to between 1.0 and 1.3 million barrels per day. It will bring western oil to refineries in Ontario, Michigan, Ohio, Pennsylvania, Quebec and New York by early 2014. New Brunswick will also refine some of this western Canadian crude and export some crude and refined oil to Europe from its deep water oil ULCC loading port. Although pipelines can be built under the sea, that process is economically and technically demanding, so the majority of oil at sea is transported by tanker ships. Similarly, it is often more economically feasible to transport natural gas in the form of LNG, however the break even point between LNG and pipelines would depend on the volume of natural gas and the distance it travels. Growth of market
The market size for oil and gas pipeline construction experienced tremendous growth prior to the economic downturn in 2008. After faltering in 2009, demand for pipeline expansion and updating increased the following year as energy production grew. By 2012, almost 32,000 miles (51500 km) of North American pipeline were being planned or under construction. When pipelines are constrained, additional pipeline product transportation options may include the use of drag reducing agents, or by transporting product via truck or rail. Construction and operation
Oil pipelines are made from steel or plastic tubes with inner diameter typically from Most pipelines are typically buried at a depth of about To protect pipes from impact, abrasion, and corrosion, a variety of methods are used. These can include wood lagging (wood slats), concrete coating, rockshield, high density polyethylene, imported sand padding, sacrificial cathodes and padding machines. Crude oil contains varying amounts of paraffin wax and in colder climates wax buildup may occur within a pipeline. Often these pipelines are inspected and cleaned using pigging, the practice of using devices known as "pigs" to perform various maintenance operations on a pipeline. The devices are also known as "scrapers" or "Go devils". "Smart pigs" (also known as "intelligent" or "intelligence" pigs) are used to detect anomalies in the pipe such as dents, metal loss caused by corrosion, cracking or other mechanical damage. These devices are launched from pig launcher stations and travel through the pipeline to be received at any other station down stream, either cleaning wax deposits and material that may have accumulated inside the line or inspecting and recording the condition of the line. For natural gas, pipelines are constructed of carbon steel and vary in size from in diameter, depending on the type of pipeline. The gas is pressurized by compressor stations and is odorless unless mixed with a mercaptan odorant where required by a regulating authority. Ammonia

Реализация
Трубопроводы обычно прокладываются под землей, поскольку температура там менее подвержена колебаниям. Так как трубопроводы обычно металлические, это помогает снизить расширение и сжатие, которые могут происходить при изменении погоды. Однако в некоторых случаях необходимо перекинуть трубопровод через долину или реку, используя трубопроводный мост. Трубопроводы для систем центрального отопления часто прокладывают на поверхности земли или над землей. Трубопроводы для транспортировки нефти в районах вечной мерзлоты, такие как Трансаляскинский нефтепровод, часто прокладываются над землей, чтобы избежать таяния мерзлого грунта горячей нефтью, что могло бы привести к оседанию трубопровода в землю.
Содержание
Обслуживание трубопроводов включает в себя проверку соответствия уровней катодной защиты заданному диапазону, наземный, водный и воздушный мониторинг строительства, эрозии или утечек, а также пропуск очистных снарядов, если транспортируемая среда обладает коррозионными свойствами. Правила обслуживания трубопроводов в США изложены в разделах Кодекса федеральных правил (CFR): 49 CFR 192 – для газопроводов природного газа и 49 CFR 195 – для трубопроводов для транспортировки жидких нефтепродуктов.
Регулирование
В США наземные и морские трубопроводы, используемые для транспортировки нефти и газа, регулируются Администрацией безопасности трубопроводов и опасных материалов (PHMSA). Некоторые морские трубопроводы, используемые для добычи нефти и газа, регулируются Службой управления минеральными ресурсами (MMS). В Канаде трубопроводы регулируются либо провинциальными органами регулирования, либо, если они пересекают границы провинций или границу между Канадой и США, Национальным энергетическим советом (NEB). Государственные нормы в Канаде и Соединенных Штатах требуют, чтобы подземные топливопроводы были защищены от коррозии. Зачастую наиболее экономичным методом защиты от коррозии является использование трубопроводного покрытия в сочетании с катодной защитой и технологиями мониторинга трубопровода. Наземные трубопроводы не могут быть защищены катодной защитой. Покрытие является единственной внешней защитой.
Трубопроводы и геополитика
Трубопроводы для основных энергетических ресурсов (нефть и природный газ) – это не просто элемент торговли. Они затрагивают вопросы геополитики и международной безопасности, а строительство, прокладка и контроль над нефтегазопроводами часто играют важную роль в государственных интересах и действиях. Ярким примером «трубопроводной политики» стал кризис в начале 2009 года, когда спор между Россией и Украиной, формально касавшийся ценообразования, привел к серьезному политическому кризису. Российская государственная компания «Газпром» прекратила поставки природного газа в Украину после провала переговоров с украинским правительством. Помимо прекращения поставок в Украину, был остановлен транзит российского газа через территорию Украины – включая почти весь объем, идущий в Юго-Восточную Европу, и часть поставок в Центральную и Западную Европу, что вызвало серьезный кризис в ряде стран, сильно зависящих от российского газа. Россию обвинили в использовании этого спора как инструмента давления, чтобы не допустить вмешательства других держав, особенно Европейского Союза, в дела «ближнего зарубежья». Нефте- и газопроводы также играют значительную роль в политике Центральной Азии и Кавказа.
Определение опасности
Поскольку растворительная фракция дильбита обычно содержит летучие ароматические углеводороды, такие как нафта и бензол, можно ожидать достаточно быстрого испарения носителя после разлива на поверхности – что, по всей видимости, позволит своевременно вмешаться, оставив лишь вязкий остаток, который медленно распространяется. Эффективные протоколы по минимизации воздействия нефтехимических паров хорошо разработаны, и нефть, вылившаяся из трубопровода, вряд ли достигнет водоносного горизонта, если за неполной рекультивацией последует поступление другого носителя (например, серии сильных ливней). Попадание бензола и других летучих органических соединений (в совокупности BTEX) в подземную среду усугубляет угрозу, исходящую от утечки из трубопровода. Особенно если после утечки последует дождь, произойдет растворение BTEX и установление равновесия бензола в воде, после чего эта смесь будет просачиваться в водоносный горизонт. Бензол может вызывать множество проблем со здоровьем и является канцерогеном, при этом максимально допустимая концентрация (MCL) по стандартам EPA установлена на уровне 5 мкг/л для питьевой воды. Хотя этот вопрос изучен недостаточно, даже однократное воздействие бензола связывают с острым развитием онкологических заболеваний. Кроме того, установлено, что воздействие бензола на сельскохозяйственных животных, в основном крупный рогатый скот, вызывает различные проблемы со здоровьем, такие как нейротоксичность, повреждение плода и смертельное отравление. Всю поверхность надземного трубопровода можно непосредственно осмотреть на предмет повреждений. Скопление нефти очевидно, легко обнаруживается и указывает на место, где требуется ремонт. Поскольку эффективность дистанционного контроля ограничена стоимостью оборудования для мониторинга, расстояниями между датчиками и необходимостью интерпретации данных, небольшие утечки в подземных трубопроводах иногда могут оставаться незамеченными.
Разработчики трубопроводов не всегда уделяют приоритетное внимание эффективному контролю за утечками. Подземные трубопроводы вызывают меньше жалоб. Они изолированы от экстремальных температур окружающей среды, защищены от ультрафиолетового излучения и менее подвержены фотодеградации. Подземные трубопроводы защищены от попадания мусора, гроз, торнадо, ураганов, града и кислотных дождей. Они защищены от гнездования птиц, повреждений, наносимых животными, и случайных попаданий дроби. Подземные трубопроводы менее уязвимы к повреждениям в результате несчастных случаев (например, автомобильных столкновений) и менее доступны для вандалов, диверсантов и террористов.
Экспозиция
Предыдущие исследования показали, что «наихудший сценарий воздействия» может быть ограничен конкретным набором условий. Благодаря передовым методам обнаружения и стандартным операционным процедурам отключения трубопроводов, разработанным TransCanada, риск значительного или крупного выброса за короткий промежуток времени, загрязняющего грунтовые воды бензолом, представляется маловероятным. Процедуры обнаружения, отключения и ликвидации последствий ограничат растворение и перенос бензола. Следовательно, воздействие бензола будет ограничено утечками, которые находятся ниже предела обнаружения и остаются незамеченными в течение продолжительного времени. Или 14,5% от общей длины трубопровода, и за 50-летний срок службы всего трубопровода ожидается от 11 до 91 случая разлива. При этом только 0,5% всех разливов за последние 10 лет превысили 10 000 баррелей.
Бензол, судьба и транспортировка
Бензол считается легким ароматическим углеводородом с высокой растворимостью и высокой летучестью. Неясно, как температура и глубина повлияют на летучесть бензола, поэтому было сделано предположение, что бензол в нефти (1% по объему) не будет испаряться до установления равновесия с водой. Когда в 2010 году в Маршале, штат Мичиган, произошел разрыв нефтепровода Enbridge Line 6B, было разлито не менее 843 000 галлонов дильбита. После обнаружения утечки были использованы боновые заграждения и вакуумные машины. Сильные дожди привели к переполнению реки через существующие плотины, и дильбит был унесен течением на 30 миль вниз по реке, прежде чем удалось локализовать разлив. Работы по восстановлению позволили собрать более 1,1 миллиона галлонов нефти и почти 200 000 кубических ярдов нефтезагрязненных отложений и мусора из речной системы Каламазу. Однако нефть продолжали обнаруживать в пострадавших водоемах в октябре 2012 года.
Несчастные случаи и опасности
Трубопроводы могут способствовать экономическому благополучию страны и, как таковые, представлять собой вероятную цель террористов или противников в военное время. Ископаемое топливо может транспортироваться по трубопроводу, железной дороге, грузовику или морским путем, хотя для экономичной транспортировки природного газа требуется его сжатие или сжижение. При транспортировке сырой нефти по этим четырем способам различные отчеты указывают на то, что трубопроводы, пропорционально, вызывают меньше человеческих жертв и материального ущерба, чем железнодорожный и автомобильный транспорт, а также меньшие разливы нефти, чем автомобильный. 4 марта 1965 года – 32-дюймовый газопровод, расположенный к северу от Начитоша, штат Луизиана, принадлежащий компании Tennessee Gas Pipeline, взорвался и сгорел из-за разрушения, вызванного коррозионным растрескиванием под напряжением, что привело к гибели 17 человек. По меньшей мере 9 человек получили ранения, а 7 домов, расположенных в 450 футах от места разрыва, были разрушены. Эта и другие аварии того времени побудили тогдашнего президента Линдона Б. Джонсона в 1967 году призвать к созданию национального агентства по безопасности трубопроводов. В том же трубопроводе произошел взрыв 9 мая 1955 года, всего в 280 метрах от места разрыва 1965 года. 16 июня 1976 года – строительная бригада в Лос-Анджелесе, штат Калифорния, повредила бензопровод. Бензин распылился, вскоре воспламенился, убив 9 человек и ранив по меньшей мере 14 других. Недопонимание относительно глубины залегания трубопровода в районе строительства, по-видимому, стало фактором, способствовавшим аварии. 4 июня 1989 года – Уфимская железнодорожная катастрофа: искры от двух проходящих поездов воспламенили газ, вытекающий из трубопровода сжиженного газа вблизи Уфы, Россия. По меньшей мере 575 человек погибли. 17 октября 1998 года – Взрыв трубопровода Джесси в 1998 году: в районе Джесси на дельте реки Нигер в Нигерии взорвался нефтепровод, в результате чего погибло около 1200 жителей деревни, некоторые из которых собирали бензин. 10 июня 1999 года – Разрыв трубопровода в парке в городе Беллингем, штат Вашингтон, привел к утечке 277 200 галлонов бензина. Бензин воспламенился, вызвав взрыв, в результате которого погибли двое детей и один взрослый. Неправильная эксплуатация трубопровода и ранее поврежденный участок трубы, который не был обнаружен, были установлены как причины аварии. 19 августа 2000 года – Разрыв и пожар на газопроводе вблизи Карлсбада, штат Нью-Мексико; в результате взрыва и пожара погибли 12 членов большой семьи. Причиной стала сильная внутренняя коррозия трубопровода. 30 июля 2004 года – Взрыв крупного газопровода в Гисленгхиене, Бельгия, недалеко от города Ат (в 30 километрах к юго-западу от Брюсселя), унес жизни по меньшей мере 24 человек и ранил 132, некоторые из которых находились в критическом состоянии. 12 мая 2006 года – Нефтепровод был поврежден вблизи Лагоса, Нигерия. По предварительным данным, погибло до 200 человек. Подробнее – о нефтяном взрыве в Нигерии. 1 ноября 2007 года – Взрыв газопровода пропана произошел вблизи города Кармайкл, штат Миссисипи, примерно в 48 километрах к югу от города Меридиан, штат Миссисипи. Двое погибли на месте, еще четверо получили ранения. Несколько домов были разрушены, а шестьдесят семей остались без крова. Трубопровод принадлежит компании Enterprise Products Partners LP и проходит от Монт-Белвю, штат Техас, до города Апекс, штат Северная Каролина. Неспособность обнаружить дефекты в трубах, сваренных методом ERW до 1971 года, стала одним из факторов, способствовавших аварии. 9 сентября 2010 года – Взрыв трубопровода Сан-Бруно: 30-дюймовый газопровод высокого давления, принадлежащий компании Pacific Gas and Electric Company, взорвался в жилом районе Крестмур, в 3,2 километрах к западу от международного аэропорта Сан-Франциско, в результате чего погибли 8 человек, 58 получили ранения и 38 домов были разрушены. Плохой контроль качества труб и строительных работ были названы факторами, способствовавшими аварии. 27 июня 2014 года – Взрыв произошел после разрыва газопровода в деревне Нагарам, район Восточный Годавари, штат Андхра-Прадеш, Индия, в результате чего погибли 16 человек и были разрушены "десятки домов". 31 июля 2014 года – В ночь на 31 июля в городе Гаосюн, Тайвань, произошла серия взрывов, вызванных утечками в подземных газопроводах. Вытекающий газ заполнил канализационные коллекторы вдоль нескольких главных магистралей, и в результате взрывов несколько километров дорожного полотна превратились в глубокие траншеи, выбрасывая транспортные средства и обломки в воздух и вызывая пожары на большой территории. По меньшей мере 32 человека погибли и 321 получили ранения.
В качестве целей
Трубопроводы могут становиться объектом вандализма, саботажа или даже террористических атак. Например, с начала 2011 года по июль 2012 года газопровод, соединяющий Египет с Израилем и Иорданией, подвергся 15 нападениям. В 2019 году топливопровод к северу от Мехико взорвался после того, как воры топлива сделали врез в трубопровод. По сообщениям, погибло по меньшей мере шестьдесят шесть человек. Во время войны трубопроводы часто становятся целью военных атак, поскольку уничтожение трубопроводов может серьезно нарушить логистику противника. 26 сентября 2022 года на трубопроводах "Северный поток-1" и "Северный поток-2", проходящих из России в Европу под Балтийским морем, произошла серия взрывов и последовавшие за ними масштабные утечки газа. Предполагается, что утечки были вызваны диверсией.
