Duplex and Super Duplex UNS S32205 Tees
The Duplex and Super Duplex UNS S32205 Tee is an essential pipe fitting used to branch a piping system, offering an unparalleled combination of high strength and exceptional corrosion resistance. Manufactured by Zeron Fasteners, the Duplex 2205 (UNS S32205) grade is specifically designed for environments where high tensile and yield strength are critical, particularly those involving chloride stress corrosion cracking. Its unique structure—a balanced blend of austenitic and ferritic phases—provides superior performance compared to conventional austenitic stainless steels. These tees are widely utilized in oil & gas, chemical processing, and desalination plants where resistance to aggressive chlorides and harsh temperatures is mandatory. Available in both equal and reducing configurations, our fittings ensure reliable, high-integrity connections in severe service applications.
