Concentric Reduced Rubber Joint High Temperature Resistance Bellows Rubber
The material selection of bellows rubber is crucial, which is directly related to the performance and service life of the joint. Generally speaking, natural rubber, nitrile rubber, chloroprene rubber and other materials are often used for the inner and outer layers, which have good elasticity, abrasion resistance, aging resistance and tear resistance. Enhancement layer is often used polyester cord fabric or steel wire ring and other high-strength materials, in order to improve the joint's pressure-bearing capacity and stability. With its unique structure and superior performance, concentric reducer rubber joint plays an important role in the pipeline system.
Characteristics of Concentric Reducer Bellows Rubber
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.
