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

Carbon Steel API X70 5L PSL 1 Pipes are primarily made of iron, containing about 0.04%–0.10% carbon, 1.0%–1.5% manganese, along with trace amounts of phosphorus and sulfur. This specific composition results in a high strength-to-weight ratio and excellent weldability. These pipes boast a minimum yield strength of 485 MPa and a tensile strength ranging from 570 to 760 MPa, making them perfect for high-pressure pipeline operations. API X70 pipes are known for their outstanding toughness and resistance to crack propagation, making them suitable for cold and harsh environments, which is essential for the long-distance transport of oil and gas.
