ASTM A182 F55 BL RF Flange - Super Duplex Stainless Steel Forged Blind Raised Face Flange
ASTM A182 F55 BL RF Flange is a premium super duplex stainless steel forged flange manufactured in strict compliance with ASTM A182 and ASME B16.5 standards. The F55 (UNS S32760) grade features a uniform dual-phase microstructure of austenite and ferrite, delivering exceptional mechanical strength, superior corrosion resistance against chloride-induced pitting, crevice corrosion and stress corrosion cracking, along with excellent weldability.
As a Blind (BL) flange with Raised Face (RF), this component is specifically engineered to terminate, seal, or isolate pipeline ends, providing reliable sealing performance and structural stability. It is widely utilized in demanding industrial piping systems including offshore, oil & gas, chemical processing, and desalination applications.
