Grooved pipe fittings comprise two main categories:
① Fittings used for connection and sealing include rigid joints, flexible joints, mechanical tees, and grooved flanges;
② Fittings used for connection and transition include elbows, tees, crosses, reducers, and blind flanges.
Grooved pipe fittings used for connection and sealing mainly consist of three parts: a sealing rubber ring, a clamp, and locking bolts. The inner rubber sealing ring is placed on the outside of the pipe being connected and mates with the pre-rolled groove. The clamp is then fastened onto the outside of the rubber ring, and finally secured with two bolts. Due to the unique sealable structural design of its rubber sealing ring and clamp, grooved fittings have excellent sealing performance, and this sealing performance increases with the increase of fluid pressure inside the pipe.
