Chanathip Nickel Alloys & Plates is a reliable manufacturer and supplier of Duplex Steel S32205 pipe fittings in Bangkok, Thailand. We produce a wide range of seamless and welded butt-weld fittings including elbows, tees, reducers, stub ends, and caps. These fittings are made according to ASTM A815 and ASME B16.9 standards, making them suitable for high-pressure and corrosive environments. Our production capabilities include solution annealing, precision machining, and strict quality control. We are committed to providing certified, durable, and corrosion-resistant fittings for both local and international clients in oil & gas, chemical processing, and marine engineering.
S32205 pipe fittings include about 22% chromium, 5–6% nickel, 3% molybdenum, and 0.14–0.20% nitrogen. Other elements like carbon, sulfur, and phosphorus are maintained at low levels to enhance corrosion resistance. The duplex microstructure improves strength and resistance to stress corrosion cracking. These fittings have a minimum yield strength of 450 MPa, tensile strength of 620–700 MPa, and elongation above 25%. Brinell hardness typically stays below 290 HB. They also offer excellent weldability and resistance to pitting, crevice corrosion, and fatigue under changing mechanical and thermal loads.

Duplex Steel S32205 pipe fittings are commonly used in industries that need high mechanical strength and corrosion resistance. Typical applications involve offshore and marine structures, subsea piping, desalination plants, heat exchangers, and chemical processing units. These fittings are great for transporting seawater, brine, and acidic or chloride-rich fluids. Their ability to endure high pressure and tough operating conditions makes them valuable in power generation, paper mills, wastewater treatment facilities, and food processing plants. S32205 fittings help cut maintenance costs and extend the life of piping systems in both static and dynamic situations.
