Screw Threaded Coupling Union Type Custom Rubber Flexible Expansion
Joint
Material of threaded rubber expansion joint
Includes the inner layer, the enhancement layer has a multilayer
spreading nylon cord fabric, rubber outer layer composite tubes.
According to the different media used rubber material is also
different, there are natural rubber, styrene butadiene rubber,
butyl rubber, nitrile rubber, three ethylene propylene rubber,
chloroprene rubber, silicone rubber, fluorine rubber, etc.
It has the functions of heat resistance, acid resistance, alkali
resistance, corrosion resistance, abrasion resistance and oil
resistance.
Features of threaded rubber expansion joint
High pressure and elastic deformation.
Advantages: high quality rubber joints recommended to reduce
vibration, noise reduction, lightweight.
