Socket Welding flange


Socket Welding Flanges

The socket welding flange is similar to a slip-on

flange except it has a bore and a counter bore dimension.

The counter bore is slightly larger than the O. D. of the

matching pipe, allowing the pipe to be inserted into the

flange similar to a slip-on flange. The diameter of the

smaller bore is the same as the I. D. of the matching pipe.

A restriction is built into the bottom of the bore which sets

as a shoulder for the pipe to rest on. This eliminates any

restriction in flow when using a socket welding flange.
