What are the Types Of API 5L Pipes?
PSL-1 is a loose standard quality for line pipe. PSL 1 Pipes are used to distribute line pipes. Grades covered by this specification are A25, A, B and “X” Grades API 5L X42 PSL1 Pipes, API 5L X46 PSL1 Pipes, API 5L X52 PSL1 Pipes, API 5L X56 PSL1 Pipes, API 5L X60 PSL1 Pipes, API 5L X65 PSL1 Pipes, API 5L X70 PSL1 Pipes, API 5L X80 PSL1 Pipes. The two digit number following the “X” indicates the Minimum Yield Strength (in 000′s psi) of pipe produced to this grade.
PSL-2 contains additional testing requirement, stricter chemical physicals, along with different ceiling limits of mechanical properties, and require Charpy impact testing conditions. Furthermore, additional testing requirements under PSL-2 include CVN testing, non-destructive inspection of seamless products, Read more
