Liam Pipes and Tubes, based in Houston, USA, stands out as a top manufacturer and supplier of high-quality tubing solutions designed for tough and demanding environments. Our Super Duplex Steel Coil Tubing is crafted from high-alloy stainless steel, built to deliver exceptional corrosion resistance, mechanical strength, and long-lasting performance. Meeting international standards like ASTM A789 and UNS S32760/S32750 grades, this tubing is perfect for continuous-length applications that need to withstand high pressure and aggressive media. At Liam Pipes and Tubes, we offer customized coil tubing solutions for the oil & gas, chemical, subsea, and offshore industries, ensuring reliability in critical operations.
Super Duplex Steel Coil Tubing is made up of 25% chromium, 7% nickel, 3.6% molybdenum, 0.3% nitrogen, along with small amounts of copper and tungsten, featuring a balanced dual-phase (austenitic-ferritic) structure. This unique composition provides excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. The tubing boasts impressive mechanical strength, with tensile strength ranging from 750–930 MPa, yield strength around 550 MPa, and elongation of 25–35%. Its outstanding weldability, fatigue strength, and resistance to localized corrosion make it ideal for high-pressure and high-temperature continuous operations in critical service conditions.
