flange
The protrusion (in the form of a disk or ring) that is connected to the end of the pipe is called a flange. Flange joints are created by screwing two flanges together and placing a sealing gasket between them. Flange connections are used in pairs; This means that one side of the flange is connected to the pipe and it is facing the other flanges from the opposite side and their connection is secured with bolts and nuts. Flanges are available and used in different types:
Threaded Pipe Flange
