Liam Pipes and Tubes, located in Houston, USA, has built a solid reputation as a manufacturer and supplier of Super Duplex Steel Welded Pipes. They specialize in providing high-performance piping solutions tailored for critical industrial sectors. These pipes are well-known for their exceptional corrosion resistance, impressive mechanical strength, and durability even in the harshest environments. Liam Pipes and Tubes is dedicated to ensuring that every product adheres to international quality standards, making them a reliable choice for clients in offshore drilling, chemical processing, marine, and power generation industries. With cutting-edge production capabilities and a strong commitment to precision and reliability, the company offers Super Duplex Welded Pipes that are designed for long-lasting, demanding applications.
Super Duplex Steel Welded Pipes are crafted from a dual-phase alloy that typically contains around 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and 0.2–0.3% nitrogen, along with iron and trace elements. This unique composition strikes a perfect balance between ferritic and austenitic stainless steel properties, providing remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. The mechanical properties are impressive, featuring a high tensile strength of about 750 MPa and a yield strength of roughly 550 MPa, along with excellent toughness and weldability. These traits make them ideal for applications that face high mechanical stress and aggressive chemicals.
