API 5L is suitable for transporting gas, water, and oil, and is usually found in the hydrocarbon petroleum and natural gas industry. PSL-1 is a loose standard quality for line pipe, whereas 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, certification to SR15, and mandatory traceability throughout the entire production process.

API 5L line pipe Seamless and welded pipe of all grades have PSL1 and PSL2 two product specifications, they are different on chemical composition, manufacturing processes, mechanical strength, heat treatment, test records, traceability etc. PSL is the short name of product standard level. For all grades of PSL2 pipes, the maximum Phosphorus is 0.
So, the only difference is a grade lower than A. Other than these three elements, for PSL2 pipe meeting, the Carbon equivalent is mandatory whereas for PSL1 pipe it is only required if the purchaser has specified SR SR18 means Supplementary Requirement No.
PSL1 pipes are available through size 0. These two basic specifications are in part recognized as different levels of physical and technical requirements.
