Socket Weld Flange

The basic shape of the Socket Welding Flanges is the same as that with the neck flat welding flange, the inner hole of the flange is provided with a hole, the pipe is inserted into the bore, the weld is welded in the back of the flange, because the gap between the socket flange and the CAO is easy to produce corrosion, and the corrosion can be avoided if a seam is welded inside. The fatigue strength of the socket flange welded on both sides of the inner and outer surfaces is 5% and the static strength is the same. When using this socket flange, the inner diameter is one of the same diameter as the pipe.
