Product Details
Product Description:
Flexible rubber bellow joint consists of outer rubber, inner rubber, framework layer, and reinforcing bar and flange. Relying on rubber’s special performances as long range elasticity, air impermeability, medium, climate and radiation resistance, rubber expansion couplings can reduce the vibration and noise of pipeline, and can be caused by the temperature change of heat bilges cold shrink compensation effect.
Applications:
It is widely used in chemical engineering, construction, water supply, drainage, petroleum, light and heavy industries,refrigeration, sanitation, water heating, fire protection, electric power and other basic projects. According to different materials can be made into acid, alkali, corrosion, oil, high temperature, radiation, wear resistance, aging and other varieties, to adapt to a variety of media and environment.
1. Allow for four way movements.
2. Precision molded of synthetic rubber and nylon cord.
3. Execllent ability to absorb vibration and noise.
4. Withstand high pressure.
5. Corrosion resistant.
6. Easy to install, use floating flange.
