Duplex and Super Duplex UNS S32760 Blind Flanges

The Duplex and Super Duplex UNS S32760 Blind Flange is a solid, circular metal forging with no central bore, fundamentally designed to terminate or isolate the end of a piping system, a valve opening, or a pressure vessel nozzle. As the component that must withstand the entire fluid pressure across its surface, it requires the highest level of material integrity and strength. Manufactured from the elite Super Duplex UNS S32760 alloy (also known as F55 or Zeron 100), these flanges possess a dual-phase microstructure that provides superior mechanical strength and unparalleled defense against environmental degradation, specifically pitting, crevice corrosion, and chloride stress corrosion cracking (SCC). The high Pitting Resistance Equivalent Number (PREN) of the F55 grade ensures reliable sealing in high-chloride and sour service conditions. Zeron Fasteners manufactures and supplies these essential isolation flanges in strict compliance with specifications like ASME B16.5 and the material standard ASTM A182 F55, critical for petrochemical, offshore, and desalination facilities.
