What is Carbon Steel API X70 5L PSL 1 Pipes​?

The Carbon Steel API X70 5L PSL 1 Pipes are primarily made up of carbon (≤0.26%), manganese (≤1.65%), phosphorus (≤0.03%), and sulfur (≤0.03%), striking a perfect balance between strength and ductility. They feature a minimum yield strength of 485 MPa and a tensile strength of 570 MPa, ensuring remarkable toughness, weldability, and resistance to fatigue. These pipes undergo heat treatment and rigorous testing to guarantee consistent performance, making them ideal for high-stress and long-distance transmission needs.
