Carbon Steel SWRF Flange, Color : Silver 0.5-24 INCH

Socket weld flanges are a type of pipe flange used in small-size, high-pressure piping systems. They are similar to slip-on flanges but have a socket (recess) on the inner bore instead of having the flange slide over the pipe. The pipe is inserted into the socket, and then fillet-welded on the outside to create a secure and leak-resistant connection.
