Weld-neck flange: long tapered neck that is butt-welded onto matching pipeCarbon steel, forged to ASTM A105ANSI Class 600 drilling to ANSI B16.5, mates with any ANSI 600 flanged equipment
A weld-neck flange in carbon steel with ANSI Class 600 drilling. Forged to ASTM A105, dimensionally precise and Carbon steel forged to ASTM A105 covers general utility, water and yard piping where stainless is not required. Weld-neck flanges give the cleanest internal bore and the best fatigue resistance for cyclic service. As a weld neck flange on ANSI Class 600 piping, it bolts straight onto existing mating flanges without an adaptor or transition piece.
