China Flexible Rubber Expansion Joint Connector - High-Quality Suppliers & Factory for Shock Absorbers
div容器
Flexible rubber expansion joint is also one type of non metallic expansion joint which Shandong Hesper supply. Rubber expansion Joints also called rubber joints, soft rubber joints, rubber flexible joints, shock absorbers, pipeline shock absorbers, shock-absorbing throats, etc. They are a kind of pipe joints, which have high elasticity, high air tightness, medium resistance and weather resistance.
Hesper rubber joints are made by rubber and polyester cord which has high strength and strong cold and heat stability, undergoes high pressure and high temperature, then vulcanized by molds. Therefore, flexible rubber joints take the advantage of rubber's elasticity, high air tightness, medium resistance, weather resistance and radiation resistance, etc. They can connected with pumps, valves, fire-fighting equipment, pipelines with high vibration, and pipelines with frequently changes in cold and heat, and the valve body is tightly connected, with strong pressure resistance and good sealing performance.
