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.
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.
