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.
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. Most FERC, DOT, or FEMSA lines require PSL-2, meaning these types of requirements are a must when supplying pipe for pipelines that are regulated by any of these governing bodies.
PSL2 pipes are more used for natural gas pipe or crude oil line pipe where there are high requirements for pipe pressure, pipe anti-corrosin ability, high mechanical strength etc.
