Carbon Steel API X65 5L PSL 1 Pipes primarily consist of iron, with a carbon content of about 0.05%–0.09%, along with 1.2%–1.45% manganese and trace amounts of phosphorus and sulfur. This specific composition strikes a perfect balance between strength, weldability, and toughness. These pipes boast a minimum yield strength of 450 MPa and a tensile strength that ranges from 535–760 MPa. Designed for durability and resistance to stress corrosion, API X65 pipes are ideal for challenging environments. Their mechanical properties make them suitable for high-pressure flow systems, ensuring reliable long-term performance even in tough pipeline operations.
