A Socket Weld Flange is a type of flange designed for connecting pipes using socket welding.The pipe is inserted into the socket of the flange and then welded around the outer edge.This method provides a strong and leak-proof joint with accurate pipe alignment.It is commonly used in high-pressure and small-diameter piping systems.Socket weld flanges are highly resistant to pressure and temperature.They are widely applied in oil, gas, petrochemical, and steam pipeline systems .
