10.0Mpa 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. Threaded expansion joint is formed by rubber double sphere and metal flat movable joint vulcanized by composite model of inner layer, reinforcing layer and outer rubber layer. Material of screw rubber joint: Forging / Casting (round or square), surface treatment is galvanized; material: the inner layer is heat-resistant rubber, the outer layer is aging resistant rubber, and the middle is reinforced cotton cord fabric.
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 production flow
Do you know how is a high quality Screw rubber joint made?Let's see with JINGNING.
Screw rubber joint advantages
A: Screw rubber joint 15 minutes galvanized, high pressure resistance, high temperature resistance, oil resistance, wear resistance, corrosion resistance, acid and alkali resistance.
B:Screw rubber joint are connected with pumps, valves, fire-fighting equipment, pipes with large vibration and pipes with frequent cold and hot changes.
C: The natural rubber content of screw rubber joint is 47%, which can be used continuously for 15 years without aging.
Screw rubber joint application
The surface of the wave compensation element of the screw rubber joint is rubber, and the inner layer is made of multi-layer strong fiber or steel strip (wire). The fiber layer or steel strip (wire) has been extended to the end of the rubber flange, and the flange has a hard steel wire skeleton. The screw rubber joint can compensate axial, lateral and angular displacement, reduce noise, absorb vibration, and has anti-corrosion performance. The screw rubber joint has excellent high pressure resistance, good elasticity and large displacement compensation. The screw rubber joint has good vibration and noise reduction performance and is easy to install. Screw rubber joints are widely used in water supply and drainage, HVAC, fire protection, compressor, paper making, pharmaceutical, ship, water pump, fan and other pipeline systems.
