Duplex and Super Duplex UNS S32205 Flanges

The Duplex and Super Duplex UNS S32205 Flanges are critical components used to connect pipes, valves, and equipment, allowing for easy disassembly and maintenance in piping systems. Manufactured by Zeron Fasteners, these flanges are forged from Duplex 2205 (UNS S32205), a highly versatile grade known for its exceptional strength, toughness, and superior resistance to pitting and chloride stress corrosion cracking compared to standard austenitic stainless steels. This dual-phase microstructure makes them ideal for demanding applications in offshore platforms, oil and gas pipelines, pulp and paper processing, and seawater desalination plants. We supply all common types, including Weld Neck, Slip-On, Blind, and Socket Weld, ensuring a secure, high-pressure, and leak-free joint in severely corrosive and high-temperature environments.
