Liam Pipes and Tubes stands out as a leading manufacturer and supplier of Super Duplex Steel Seamless Tubing in Houston, USA. We specialize in high-performance tubing solutions designed for critical applications in tough and corrosive environments. Our Super Duplex seamless tubes, including grades like UNS S32750 and S32760, are celebrated for their exceptional strength, impressive corrosion resistance, and remarkable performance in chloride-rich and high-pressure systems. Built to meet ASTM and ASME specifications, our tubing ensures excellent weldability, fatigue resistance, and precise dimensions. We proudly serve industries such as offshore, petrochemical, and power generation, delivering globally trusted tubing solutions with unwavering quality and reliability.
Super Duplex Steel Seamless Tubing generally consists of about 24–26% chromium, 6–8% nickel, 3–5% molybdenum, along with some nitrogen and manganese, with iron making up the rest. This unique alloy structure combines both austenitic and ferritic phases, providing outstanding mechanical strength (with tensile strength reaching up to 800 MPa), yield strength exceeding 550 MPa, and remarkable resistance to stress corrosion cracking, pitting, and crevice corrosion. Its excellent corrosion fatigue strength and weldability make it perfect for high-stress and aggressive applications in chemical processing, marine, and offshore settings.
