The Materials of Natural Gas Pipeline and Its Characteristics

Natural gas pipeline refers to the pipeline that transports the natural gas (including the production of oil associated gas) from the mined land or processing plant to the city gas distribution center or industrial enterprise users, also known as gas line. In the world pipeline overall length, natural gas pipe accounts for about half.


The steel pipe is the main material of the natural gas pipeline. Modern gas gathering lines and gas line are made of steel pipes those connected by welding. There are various kinds of steel pipe, including seamless steel pipe, spiral welded pipe, longitudinal welded pipe. Seamless steel pipe be appropriate for natural gas pipe that the diameter is below 529mm, and spiral welded pipe and longitudinal welded pipe are suitable for large diameter pipe.


Features of natural gas pipeline:


(1) The gas line system is a continuous closed conveyor system.
(2) From the transport, storage to the user, natural gas is with high pressure.Steel pipe is that the material utilized in gas transmission systems pipes-these pipes area unit massive in diameter and canopy over a quarter-million miles of our nation. gear pipe is created of 1/4-inch to 1/2-inch thick steel, and has special coatings and "cathodic" protection -- an electrical current that controls corrosion on the metal surface through electro-chemistry.
(3) Due to the small proportion of transported natural gas, the influence of static pressure head is much smaller than that of liquid. In design, when the height difference is less than 200 meters, the static pressure head is negligible, and the line is almost without limited by the longitudinal terrain.
(4) There is no harms of water dashing of water pipeline.
(5) Once an accident occurs, natural gas pipe is very dangerous and extensively affected. Once the natural gas pipeline rupture, it will release plenty of energy, and its tear length is longer. If the discharge of natural gas meets open fire, also easy to lead to fire.


Pipe Application: Natural Gas Pipeline


Steel pipe is that the material utilized in gas transmission systems pipes-these pipes area unit massive in diameter and canopy over a quarter-million miles of our nation. gear pipe is created of 1/4-inch to 1/2-inch thick steel, and has special coatings and "cathodic" protection -- an electrical current that controls corrosion on the metal surface through electro-chemistry. Natural gas inject pipes typically vary from sixteen to forty eight inches in diameter, however most interstate pipelines area unit between twenty four and thirty six inches in diameter. The pipe consists of robust steel material that meets the standards of the yankee rock oil Institute. The pipe is additionally lined with a specialised coating (e.g., fusion bond epoxy) to make sure that it doesn't corrode. additionally, electrode protection is usually wont to push back corrosion and corrosion. gas travels at high pressures of two hundred to one,500 pounds per sq in (psi) that reduces the degree of gas being transported by up to 600 times and provides the propellant force to maneuver it through the pipeline.
