Types Of API 5L Pipes?
What are the Types Of API 5L Pipes?
When authoring the standards, the technical committee recognized that there are two basic Product Specifications Levels (PSL) of technical requirements and therefore developed PSL 1 and PSL 2.
API 5L PSL1 Standards :
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.
API 5L PSL2 Standards :
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
