Threaded Pipe Flanges Definition:

Threaded flange means the inner bore of a flange is thread,the shape of the threaded flange is like a slip on flange,so the threaded flange could be plate shape or with a hub for longer thread.

Threaded Flange Joint:

The threaded pipe flange is connected to a pipe with a external thread on the pipe end,so the flange thread should have same thread specification with the pipe thread,the advantage of a threaded flange is that the piping system would be easily to assembly because there is no welding in this piping joint.

Sealing of a Threaded Flange:

The threaded flanges are usually supplied with a raised face (RF) or flat face (FF) sealing face.When a raised face is necessary for threaded pipe flanges,the standard height should be 1/16″ for the face under class400.If the threaded pipe flanges is same or more than class 400,the standard threaded pipe flange raised face height should be 1/4″
