The X65Q PSL2 steel pipe strictly complies with the PSL2 requirements of API SPEC 5L 46th Edition (Steel pipes for pipeline transportation systems in the petroleum and natural gas industries), covering core indicators such as chemical composition, tensile properties, and impact testing. The X65Q pipes supplied by GNEE Group undergo 100% ultrasonic testing (UT), radiographic inspection (RT), and hydrostatic testing to ensure defect-free delivery.
