Welded Neck Flange

Weld neck flanges have a neck that is welded directly to  the pipe section. In comparison with other flange types, a weld neck flange can also be welded directly on a fitting. The inside diameter of the whole flange and outside diameter of the neck of the flange will match the in- and outside diameter of the pipe. Weld neck flanges are often used in applications with high pressure.

Weld neck flanges from our manufacturing include ANSI B16.5, ASME B16.47 Series “A” , and ASME B16.47 Series “B” weld neck flanges.
