Product Description
ASTM A182 F51 BL RF Flange, Duplex Stainless Steel Blind Raised Face Flange
Brief Introduction
ASTM A182 F51 BL RF Flange is a duplex stainless steel blind flange manufactured in accordance with ASTM A182 and ASME B16.5 standards. F51 duplex stainless steel combines high strength with excellent resistance to pitting, crevice corrosion and stress corrosion cracking. As a Blind (BL) flange with Raised Face (RF), it is used to terminate, seal or isolate pipeline ends, widely applied in aggressive environments including offshore, oil & gas, chemical and seawater systems.
