ASME B16.5 Alloy steel flange A182 F11 Flange fittings RF WN 1.5" Sch XXS class 2500#
We supply SAF 2205® duplex stainless steel welding neck (WN) flanges manufactured in strict compliance with ASTM A182 F51/F60 and ASME B16.5 standards, made from UNS S31803/S32205.
This duplex alloy offers excellent corrosion resistance, high mechanical strength, and good weldability, effectively resisting chloride-induced stress corrosion cracking. The WN design ensures smooth pipeline transition, reduced stress concentration, and reliable full-penetration welding, ideal for high-pressure and high-corrosion applications in oil & gas, chemical processing, and marine engineering. All flanges are forged and undergo 100% dimensional inspection and NDT testing.
