Difference Between PSL1 and PSL2 Pipe
PSL1 Vs PSL2 Pipe
The American Petroleum Institute (API) designates different specifications of API line pipe. There are two specs PSL-1 and PSL-2 comes under API 5L. These specs cover seamless and welded API steel line pipe from grades X42 through X80. API 5L Line Pipes is suitable for transporting fluids such as gas, water, and oil, and is usually found in the hydrocarbon petroleum and natural gas industry. PSL-1 and PSL-2 are standards that have been put in place to help with the more strict requirements for each grade. API 5L PSL2 are known for better performance in comparison to PSL1 as it has stricter inspection requirements, chemical composition and mechanical performance requirements. API Line pipe production should include the hydraulic pressure test, and standards are not allowed to nondestructive generation of hydraulic pressure, nondestructive inspection is not required for PSL1, while each API 5L PSL2 pipe shall go through nondestructive examination one by one.
