API 5LGr.B Black Painted Line Pipe
API is the abbreviation of American Petroleum Institute. It is an American oil industry organization that provides important weekly data on American oil consumption and inventory level.
API5LGR.B Line pipes are used to transport the oil, steam, and water extracted from the ground to the petroleum and natural gas industrial enterprises through line pipes. Line pipes include seamless pipes and welded steel pipes. The pipe ends have flat ends, threaded ends and socket ends; its connection The method is welding, coupling connection, socket connection, etc. A large number of pipelines are used to transport fluids, such as oil, natural gas, water, gas, steam, etc. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used to produce various conventional weapons, barrels, and shells.
