Concentric reducer rubber joint is also called reducer shock absorber, expansion joint, damping throat and soft joint. The utility model is a flexible joint of a metal pipe, which is composed of a rubber ball, a loose metal flange with an inner rubber layer, nylon cord fabric reinforcement and an outer rubber layer. At present, the joint adopts advanced production technology. The inner layer is in a high-pressure state in the production process. The nylon cord is well combined with the rubber layer. The working pressure is high, and the quality is better than the 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 of concentric reducer rubber joint
1. Small size, light weight, flexibility, convenient installation and maintenance
2. It reduces the transmission of structural noise and has strong shock absorption.
3. It has the ability of horizontal displacement, axial displacement and angular displacement, and has the characteristics of flange reconstruction and non parallelism.
4. Prevent the corrosion of the inner wall of concentric reducing rubber joints in high temperature, acid-base and oil resistant pipelines and prolong their service life.
