DUPLEX STEEL SOCKET WELD FITTINGS

Duplex Steel Socket Weld Fitting S31803

Duplex Steel Socket Weld Fittings are high-performance alloy steel fittings known for their exceptional strength, superior corrosion resistance, and excellent resistance to stress corrosion cracking. These fittings combine the advantages of austenitic and ferritic stainless steels, making them ideal for high-pressure and high-temperature piping systems.

Duplex Steel Socket Weld Fittings are extensively used in compact piping layouts where strong, leak-proof joints are required, especially in oil & gas, chemical processing, marine, power generation, and offshore applications.

Duplex Steel Socket Weld Fittings are available in standard duplex grades to meet various service conditions. The most commonly supplied grades include Duplex S31803 (UNS S31803) and Duplex S32205 (UNS S32205), offering excellent corrosion resistance, high mechanical strength, and long service life.
