Aatir Steel, a trusted supplier and manufacturer located in Cairo, Egypt, provides top-notch Carbon Steel API 5L X70 PSL 1 pipes designed for tough pipeline applications. These pipes are crafted to comply with the API 5L specification, specifically the X70 grade under PSL 1 (Product Specification Level 1), which guarantees essential mechanical and chemical properties for the transmission of oil, gas, and water. Renowned for their impressive yield strength, durability, and ease of welding, these pipes are perfect for long-distance pipelines that need to withstand high pressure and challenging environmental conditions. Aatir Steel offers these pipes in a range of sizes, wall thicknesses, and lengths to cater to the unique needs of each project.
The API 5L X70 PSL 1 pipes are constructed from high-strength low-alloy carbon steel, typically containing less than 0.26% carbon, along with manganese, phosphorus, sulfur, and trace amounts of micro-alloying elements like niobium, vanadium, or titanium. These enhancements boost the pipes’ strength and toughness. With a minimum yield strength of 485 MPa and a minimum tensile strength of 570 MPa, they are well-suited for high-stress applications. Although PSL 1 has less rigorous testing and chemical composition standards compared to PSL 2, it still guarantees reliable mechanical performance for standard pipeline operations.
