Casing pipe has different standards.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 casing pipe is a loose standard quality for line pipe, whereas PSL-2 casing pipe 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.
