API 5L X70 PSL2 Seamless Steel Pipe
API 5L X70 is a premium grade piping material specified in API 5L standards, also known as L485 due to its minimum yield strength of 485 MPa (70,300 psi). Available in seamless (SMLS), ERW, and SAW types, it is widely used for oil and gas transmission. This PSL2 grade offers enhanced mechanical properties and stricter chemical composition controls for high-performance applications.
