Expansion Joint

Rubber joint is a pipe connection with high elasticity, high air tightness, medium resistance and weather resistance. Rubber joints are generally composed of inner rubber layer, fabric strengthening layer, middle rubber layer, outer rubber layer, end reinforcement metal ring or steel This product takes advantage of the advantages of rubber, such as high elasticity, high gas resistance, medium resistance, weather resistance and radiation resistance, can reduce the vibration and noise of pipeline, and can compensate the thermal expansion and cold contraction caused by temperature change.
