Socket Welding Flanges

Socket-Weld Flanges has a female socket in which pipe is fitted. Fillet welding is done from outside on the pipe.

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 machine pipe A restriction is built into the bottom of the bore which sets as a shoulder for the pipe to rest on.

When using a socket weld flange, the inner diameter needs to be the same as the inner diameter of the pipe. The socket flange is only suitable for pipes with a nominal diameter of 150 or less.
