Weld Neck Flange or welding neck flange can be differentiated from all other types of flange by their long tapered hub. In addition, there is also a gentle transition of thickness in the region of the butt weld that joins them to pipe or a fitting.
Weld Neck flanges or welding neck flanges are best suited for severe service conditions, whether loading conditions are substantially constant or fluctuate between wide limits.
Weld Neck Flanges are flanges with the wall thickness of the flange having the same dimensions of the matching pipe, the lighter the pipe is, the larger the bore, conversely, the heavier the pipe, the smaller the bore, they are normally used for high pressure, cold or hot temperature.
