ASTM A283 T91 P91 P22 A355 P9 P11 4130 42CrMo 15CrMo Alloy Carbon Steel Pipe ST37 C45 SCH40 A106 Gr.B A53 Seamless Steel Tube
A line pipe is a steel pipe used for transporting oil, gas, or water over long distances. It is made from high-strength steel that can withstand the high pressures and temperatures involved in transportation. Line pipes must meet strict standards set by organizations like the American Petroleum Institute (API). API 5L is a common standard for this. They are produced in various sizes, from small-diameter pipes used for residential plumbing to large-diameter pipes used for major pipelines. They can be either seamless or welded. A seamless line pipe is made from a single piece of steel, while the second type is made by joining steel plates together. Line pipes have properties like diameter, wall thickness, and steel grade that determine the strength and durability of the line pipe. The most common steel grades used for line pipes are Grades B through X80. Higher grades of steel provide better strength, reliability, and rust resistance but are more expensive.
