Screw Rubber Joint Double Sphere EPDM Threaded Expansion Joint
Screw rubber joint is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. The screw expansion joint is made of rubber double ball and metal plate movable joint by vulcanization of inner layer, reinforcing layer and outer layer. Screw rubber joint material: Forging / Casting (round or square), surface treatment galvanized; Screw rubber joint ball material: the inner layer is heat-resistant rubber, the outer layer is aging resistant rubber, the middle is reinforced cotton cord cloth.
Features of Screw rubber joint
Screw rubber joint features:
1. The Screw rubber joint can reduce the noise produced by the vibration of the pipeline pump, and has strong damping capacity.
2. The Screw rubber joint is easy to install and operate, simple and flexible.
3. The Screw rubber joint is a kind of inner seamless high pressure rubber joint made of rubber soft joint. The Screw rubber joint can effectively prevent the corrosion of the inner wall of rubber soft joint caused by high temperature resistance, acid and alkali resistance and corrosion medium in oil resistant pipeline, and improve the service life.
4. After the Screw rubber joint is installed, it can absorb the lateral, axial and angular displacement caused by the vibration of the pipeline. The Screw rubber joint is not limited by the imbalance of the pipe with the neutral flange.

Screw rubber joint application
Screw rubber joint can not only compensate axial, lateral and angular displacement, reduce noise, absorb vibration, but also screw rubber joint has anti-corrosion performance. Screw rubber joint also has excellent high pressure resistance, good elasticity and large displacement compensation. Moreover, the screw rubber joint has good vibration and noise reduction performance and is easy to install. Therefore,screw rubber joint is widely used in water supply and drainage, HVAC, fire protection, compressor, papermaking, pharmaceutical, ship, water pump, fan and other pipeline systems.
