What is a threaded flange?

Threaded flange is also called screwed flange,it is similar to slip-on flange,but the inner bore is thread.The threaded flange is connected to a pipe with a external thread on the pipe end,so the flange thread should has the same thread specification with the pipe thread.Threaded flanges are easily to assembly without welding in the piping system and they are often used for small diameter,high pressure requirements.

Sealing face of threaded flange:

Threaded pipe flanges are typically provided with a raised face, flat face, or RTJ facing.When a raised face is necessary for threaded pipe flanges,the standard height is 1/16″ for threaded pipe flanges under 400#.For threaded pipe flanges of 400# and up, the standard threaded pipe flange raised face height is 1/4″.
