Liam Pipes and Tubes stands out as a top-notch manufacturer and supplier of Super Duplex Steel EFW Pipes, proudly based in Houston, USA. We specialize in high-quality Electric Fusion Welded (EFW) pipes crafted from Super Duplex stainless steel, which is celebrated for its remarkable strength, outstanding corrosion resistance, and top-tier performance in tough environments. Designed to meet the rigorous demands of the oil & gas, petrochemical, marine, and desalination sectors, our Super Duplex EFW pipes are produced with meticulous attention to detail and strict quality standards. At Liam Pipes, we guarantee durability, reliability, and cost-effectiveness for high-pressure and high-temperature applications across essential industrial fields.
Super Duplex Steel EFW Pipes are generally made up of Chromium (24–26%), Nickel (6–8%), Molybdenum (3–5%), Nitrogen (0.2–0.3%), along with balanced amounts of Iron, Manganese, and other elements. This cutting-edge alloy boasts impressive mechanical properties, featuring a tensile strength of 750–950 MPa, yield strength of 550–650 MPa, and an elongation of 25–30%. Its unique dual-phase microstructure (austenitic and ferritic) significantly boosts resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking. The EFW process guarantees smooth internal surfaces, precise dimensions, and strong weld integrity, making these pipes perfect for extreme operational conditions.
