Socket Weld Flange Class 150

Product Detail

socket weld flange class 150


Socket weld flange class 150 is referred to as (SW flange), the basic shape of socket weld flanges is similar with flat welding flange, that is, open a section of hole in the inside of flange, insert the pipe into the hole and welded them, in the back of the flange welding a circle of welds, due to there is gap between socket weld flange and trough, it's easy to produce corrosion, if the inside welded a seam can avoid this corrosion. The fatigue strength of the socket flange welded on both sides is 5% and the static strength is the same as that of the flat welding flange. When using this socket flange, the inner diameter of the pipe must be the same as that of the tube. The socket flange is only suitable for pipes with a nominal diameter of 150 or less.
