X70 pipeline site welding technology and quality control points

The X70 pipeline steel is API 5L pipeline steel with a minimum yield strength of 70300psi, or 485 MPa.In fact, in the standard of API 5L, the pipeline steel pipe is divided into two grades, that is, PLS1 steel pipe that only requires strength grade and PSL2 steel pipe that requires more performance parameters. PSL2 steel pipe is required to mark its rolling method, such as thermo-mechanical controlled rolling, marked with M, and Q for quenching.
