Product Introduction
Rubber Expansion Joint is also called shock absorber, pipe shock absorber, shock absorber throat, soft joint, rubber joint, rubber expansion joint, flexible rubber joint,non-metallic expansion joint, flexible joint, flexible rubber expansion joint, rubber expansion bellow etc.

Rubber Expansion Joint is flexible metal pipe couplings, and is composed of loose metal flanges and rubber tube body, which is compounded with inner rubber layer, polyester cord fabric and outer rubber layer. With advantages like high pressure resistance, good elasticity, large displacement volume, easy installation, balancing pipe deviation, absorbing vibration and reducing noise, Rubber Expansion Joint can be widely used in pipe systems of sectors such as water supply and drainage, recycled water, HVAC, fire fighting, paper, pharmaceutical, oil chemicals, shipbuilding, water pumps, compressors, fans etc. 

Common type of Rubber Expansion Joint is used to transport air, compressed air, water, sea water, oil, acid and alkali, of which temperature ranges from -15 ℃ to 120 ℃.

Special type of Rubber Expansion Joint is used to transport the media above of which temperature ranges from -30℃ to 250℃ or strong alkali, strong acid and solid-state materials.
