Yodsak Tube Fittings, based in Bangkok, Thailand, is a reputable manufacturer and supplier known for its high-performance tube fittings tailored for tough industrial applications. Among their standout products are the Super Duplex Steel Tube Fittings, celebrated for their remarkable strength, resistance to corrosion, and durability in harsh environments. Designed to comply with global quality standards, Yodsak’s fittings find their place in various industries, including oil & gas, petrochemical, marine, and desalination. With cutting-edge machining capabilities and rigorous quality control, Yodsak ensures that their fittings provide leak-tight, long-lasting connections. Their Super Duplex fittings are built to perform reliably under extreme pressure, temperature, and corrosive conditions.
Super Duplex Steel Tube Fittings are crafted from grades like UNS S32750 and S32760, featuring high levels of chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and nitrogen. This well-balanced composition grants them exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking caused by chlorides. These fittings boast impressive mechanical strength, with tensile strengths ranging from 800 to 900 MPa and a yield strength of about 550 MPa. Super Duplex also retains high toughness and fatigue resistance, even in sub-zero temperatures. Yodsak guarantees precise dimensional tolerances and pressure ratings to fulfill the demands of high-integrity piping systems.

Super Duplex Steel Tube Fittings are perfect for environments that are both highly corrosive and under high pressure, where standard stainless steels just won’t cut it. They’re commonly found in offshore oil rigs, subsea pipelines, chemical processing plants, and desalination systems, ensuring reliable performance even in the harshest conditions. Their impressive strength-to-weight ratio allows for thinner wall thicknesses, making them a smart choice for demanding applications.
