What is Socket Welded Flanges( SW Flange)?
The Socket Welded Flange is also named SW Flange. The basic shape of the socket welded flange is the same as the flat welding neck flange. Pipe need to insert into the flange ID to an appropriate position and then lap welding. Because there is a gap between the socket weld flange and the groove, it is easy to cause corrosion. If a seam is welded inside, this problem can be avoided. SW Flanges both welded on the inner and outer sides have a fatigue strength 5% greater than flat welded flanges and the same static strength.
When using socket welded flanges, its ID must be the same as the ID of the pipe.
It is only suitable for pipes with DN150 or less.
