L245N is a straight seam welded pipe, where L means line, 245 means its yield strength is ≥245MPa, tensile strength is ≥415MPa, and elongation is ≥21.0%. This kind of pipeline steel pipe is very outstanding in terms of welding performance, so it is often used in the transportation of oil or natural gas. L245N straight seam steel pipe belongs to the pipeline steel series, and the implementation standard is the special technical conditions of GB/T9711-2017. In addition, L245N seamless pipe is also a national standard material for pipeline pipes used in oil and gas industry transportation. National standard materials include L290N, L360N, L390N, L415N, etc.
