Super Duplex S32550 Forged Fittings

Super Duplex Steel UNS S32550 Forged Fittings are manufactured in compliance with ASTM A182 / ASME SA182 standards to deliver superior performance in corrosive environments. With excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, these fittings are widely used in oil & gas, marine, and chemical processing industries. The unique austenitic-ferritic structure provides high mechanical strength, better thermal conductivity, and enhanced durability compared to austenitic stainless steels. Products include Forged Elbows, Tees, Crosses, Couplings, Caps, Bushings, and Unions. Available in both Threaded and Socket Weld designs, these forged fittings can be customized in different sizes, dimensions, and pressure classes as per project requirements.

Duplex Steel S32550 Socket Weld Forged Fittings are ideal for high-pressure applications requiring superior strength and leak-proof connections. Designed as per ANSI B16.11 standards, these fittings provide excellent resistance to localized corrosion such as pitting and intergranular attack. With good sulphide stress corrosion resistance, they are widely used in offshore drilling, desalination plants, and refineries. Products include Socket Weld Elbows, Tees, Crosses, Caps, and Stub Ends. The 50/50 mixture of austenitic and ferritic microstructure ensures excellent durability and mechanical performance. These fittings are supplied in customized sizes, wall thicknesses, and finishes, offering long-lasting performance in aggressive operating conditions.

Super Duplex Steel S32550 Threaded Forged Fittings are designed for easy installation without welding, making them suitable for low-pressure piping and compact systems. These fittings are manufactured under ASTM A182 specifications and provide exceptional corrosion resistance against seawater, acids, and chloride stress cracking. Common products include Threaded Elbows, Couplings, Bushings, Pipe Nipples, and Unions. With excellent abrasion resistance, erosion resistance, and strong weldability, they are used in chemical plants, power generation units, and marine structures. Duplex Steel S32550 also provides better thermal conductivity and dimensional stability compared to conventional stainless steels. They are available in various sizes, pressure ratings, and custom designs.

Duplex Steel UNS S32550 Forged Elbows are known for their superior strength and ability to withstand high-pressure and corrosive conditions. Manufactured according to ASTM A182 / ASME SA182 standards, these elbows provide excellent resistance to stress corrosion cracking and sulphide stress corrosion. They are available in 45°, 90°, and 180° designs, both in Socket Weld and Threaded types. With excellent weldability and toughness, they are widely used in petrochemical, oil & gas, and seawater applications. Duplex Steel S32550 Elbows offer high resistance to erosion and abrasion, making them reliable for long-term performance in harsh operating environments.
