Concentric Reduced Rubber Joint High Temperature Resistance Rubber Expansion Joint
Rubber expansion joint also known as vibration damper, expansion joint, pipe shock absorber, shock absorber throat, soft joint, is a flexible coupling for metal pipes. It consists of inner rubber layer, nylon cord fabric reinforcement layer, outer rubber layer composite rubber ball and loose metal flange. This structure makes the joint has good elasticity, airtightness and media resistance.
Characteristics of Concentric Reducer Rubber Expansion 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.
