Socketweld Flanges have typical application on pipes of small sizes with high pressure. They are of three different types: raised face, flat face and RTJ Facing. The pipe is inserted into the socket end of the flange and fillet weld is applied around the top. Socketweld flanges improve the flow of the fluid or gas running through the pipe.
