Concentric Reducer BS 4504 Carbon Steel Flange Epdm Bellows Flexible Rubber Expansion Joint
Product Introduction
Flexible concentric reducer rubber joints, also known as shock absorbers, expansion joints, pipeline shock absorbers, shock absorbers, and soft joints, are flexible couplings for metal pipes, which are composed of rubber spheres and loose metal flanges with an inner rubber layer, nylon cord fabric reinforcement, and outer rubber layer composite.
Product performance characteristics
1. Small size, light weight, good elasticity, easy installation and maintenance.
2. Transverse, axial and angular displacement can be generated during installation, and it is not limited by the non-concentric pipeline and non-parallel flanges.
3. It can reduce the noise of structural transmission during work and has strong vibration absorption ability.
Why do rubber joints have good corrosion resistance?
It is mainly due to the chemical stability and special molecular structure of the rubber material itself. The polymer compounds of rubber have little chemical reaction with general media and are therefore stable in many corrosive media.
