DI Grooved Pipe Fittings are a new type of steel pipe connection fittings, also called clamp connections, which have many advantages. The design specification for automatic sprinkler system proposes that the connection of system pipes should adopt grooved connectors or threaded, flanged connections; pipes with a diameter equal to or greater than 100mm in the system should use flanges or grooved connectors in sections connect.

Grooved Pipe fittings include two broad categories of products:①The pipe fittings that play the role of connection and sealing include rigid joints, flexible joints, mechanical tees and grooved flanges; ②The pipe fittings that play the role of connection transition include elbows, tees, crosses, reducers, blind plates, etc.

The grooved fittings for fire fighting system used for connection and sealing are mainly composed of three parts: sealing rubber ring, clamp and locking bolt. The rubber sealing ring on the inner layer is placed on the outside of the pipe to be connected, and matches the pre-rolled groove, then buckle the clamp on the outside of the rubber ring, and then fasten it with two bolts. Due to the unique sealable structural design of the rubber sealing ring and the hoop, the grooved joint has good sealing performance, and the sealing performance is enhanced correspondingly with the increase of the fluid pressure in the pipe.
