With cutting-edge production capabilities and thorough quality checks, Filiz Steel caters to both local and global markets, offering dependable pipes designed for tough pipeline applications that demand enhanced mechanical strength and toughness.
API 5L Grade L450 Pipe, often referred to as X70 pipe, boasts a minimum yield strength of 450 MPa and a minimum tensile strength starting at 510 MPa. Its chemical makeup typically includes carbon (≤0.26%), manganese, phosphorus (≤0.030%), and sulfur (≤0.030%), with tighter controls in PSL2 grades to improve toughness and weldability. These mechanical properties provide excellent resistance to pressure, stress, and fatigue, making L450 pipes perfect for high-pressure and high-temperature pipeline settings. The material’s outstanding weldability and formability facilitate efficient fabrication and installation.
