What is Carbon Steel API X46 5L PSL 2 Pipes​?

These pipes boast a minimum yield strength of 317 MPa and a minimum tensile strength of 434 MPa. The PSL 2 (Product Specification Level 2) standard requires more stringent control over chemical composition, improved notch toughness, and thorough testing—including non-destructive inspection and impact testing—compared to PSL 1. Available in both seamless and welded forms, these pipes offer outstanding weldability, durability, and resistance to environmental stress, making them ideal for sour service and offshore applications.
