Threaded Flange
Threaded flange is the flange with threads in it’s inner surface, as to connect the threaded pipe. The advantage
of this connection type is non-welding, so it is very convenient to install, and easy to repair. Threaded flange c-
ould be made of alloy steel, which has higher strength but bad welding performances. On the other hand, it co-
uld not used in extreme conditions as the temperature mroe than 260 ℃ or lower than -45℃, to avoid leakage.
DETAILS OF THREADED FLANGE
Threaded pipe flanges are suitable only for low-pressure systems in which there are no thermal cycles that co-
uld cause the threads to loosen. Threaded pipe flange is supplied with a tapered internal thread that the pipe s-
crews into.Threaded flange find applications in areas in which hot work (welding, burning, and grinding) is unde-
sirable.
Threaded Flange Joint:
The threaded pipe flange is connected to a pipe with a external thread on the pipe end,so the flange thread sh-
ould 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 he-
ight should be 1/4″.The threaded pipe flange commonly used in a small sizes and not very high pressure situ-
ation.The threaded flange is no welding in the joint,it means the flange could be used for some situations whi-
ch is not able to arrange a welding work.
