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.
