Liam Pipes and Tubes, a top-notch manufacturer and supplier located in Houston, USA, specializes in high-performance Super Duplex Steel Welded Tubing. These tubes are crafted for exceptional mechanical strength and corrosion resistance, even in the toughest environments. Using cutting-edge welding techniques, they strike a perfect balance between durability and cost-effectiveness, making them perfect for high-pressure and corrosive situations. With a unique dual-phase microstructure of austenite and ferrite, Super Duplex Tubing stands strong against chloride stress corrosion cracking, pitting, and crevice corrosion. Liam Pipes is committed to rigorous quality control and global standards, providing dependable tubular solutions for the offshore, petrochemical, marine, and chemical processing industries.
Super Duplex Steel Welded Tubing generally consists of 24–26% Chromium, 6–8% Nickel, 3–5% Molybdenum, 0.2–0.3% Nitrogen, with Iron as the primary component. This blend creates a well-balanced ferritic-austenitic structure, offering impressive tensile strength ranging from 700–950 MPa, yield strength exceeding 550 MPa, and elongation of about 25–30%. The tubes are highly resistant to stress corrosion cracking, pitting, and crevice corrosion, especially in chloride-rich and high-pressure settings. Welded tubing maintains its mechanical integrity and dimensional accuracy while providing good formability and weldability, making it ideal for applications that demand high strength and corrosion resistance in extreme conditions.
