What is the difference between psl1 and psl2 pipes

PSL-1 and PSL-2 are standards that have been put in place to help with the more strict requirements for each grade. These two basic specifications are in part recognized as different levels of physical and technical requirements.

PSL-1 is a loose standard quality for API 5L 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 trace-ability throughout the entire production process.

PSL2 in chemical composition, tensile properties, the impact energy, non-destructive testing and other indicators are more stringent than PSL 1. You are commenting using your WordPress. You are commenting using your Google account.

So when place the order for the API 5L line pipe, there should be stated clearly for the size, grades these general specification, also have to clarify the production standard leve, PSL1 or PSL2. PSL2 is more strictly than PSL1 on the chemical properties, tensile strength, non-destructive test, and impact test. 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.
