Threaded Flange

The threaded flange is a kind of non welded flange which is machined into a pipe thread by the inner hole of the flange and connected with the pipe with the thread. It is one of the most widely used flange structures in engineering construction that the additional pressure produced by the threaded flange connection is small. However, threaded flanges cannot be used for flammable, explosive and highly hazardous situations.
