High Temperature Resistance Concentric Reducer Rubber Joint Pipe Fittings
Concentric reducer rubber joint also known as reducing pipe shock absorber, expansion joint, shock absorption throat and soft joint .Concentric reducer rubber joint is a flexible connector of metal pipe, which is composed of rubber ball and loose metal flange with inner rubber layer, nylon cord fabric reinforcement and outer rubber layer. Concentric reducer rubber joint now using advanced production technology, the inner layer is under high pressure in the production process, the nylon cord fabric and rubber layer are better combined, and the working pressure is higher and the quality is better than that of ordinary flexible rubber joint. Concentric reducer rubber joint is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance.
Characteristics
Characteristics of concentric reducer rubber joint :Another name of concentric reducer rubber joint is reducing rubber joint. As the name suggests, the two ports are not the same size. Concentric reducer rubber joint is mainly used in the pipeline system where the outlet of the pump valve is different from the outer pipe in size, or where the pipe thickness needs to be changed according to the flow of the medium. Concentric reducer rubber joint can also be used in the place where the flow is changed, so that the pipes with different sizes can be connected in a straight line to realize the pipe connection Pipe fittings with variable diameter.
The spherical structure of the concentric reducer rubber joint not only solves the problem of different diameters in the metal pipe connection, but also has the advantages of strong damping capacity, obvious damping effect, compression and explosion-proof, good elasticity, etc. the concentric reducer rubber joint can save the installation position of the pipe and save the project cost.
