Forged Socket Welded Flange

Forged Socket Welded Flange

Socket Welded Flange of the basic shape with flat welding neck flange is the same, namely on the flange of the inner hole open one Duan Cheng hole, tube inserted into the socket hole welding, welding lap weld on the back of the flange, because the socket of the flange and the gap between Cao Zi, easy to produce corrosion, if inside weld seam can avoid this kind of corrosion.Inside and outside welding socket flange, its fatigue strength 5% larger than the flat welding flange and static strength is the same.Using this socket flange, its inner diameter should be a consistent with the pipe diameter.Socket flange applies only to below 150 caliber pipe nominal diameter.
