The multi-wave design of KST type double ball rubber joint increases the length and compensation of rubber joint. Special cold water, hot water, compressed air, natural gas, etc., with its unique design, novel structure and good sealing performance, it solves the problem of pipe burst and damage to pipe connection equipment caused by thermal expansion, cooling and contraction which effectively improve the service life of the pipeline and the protection of the equipment. A double sphere has a greater amount of compensation than a single sphere. Because the double ball rubber joint has good comprehensive performance, it is widely used in chemical engineering, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire fighting, electric power and so on. Engineering is especially suitable for pipes with large vibration and frequent changes in heat and cold.  

Double-ball rubber joint is a high-elasticity, high air-tightness, medium-resistant and weather-resistant pipe joints. The internal density is high, and it can withstand higher pressure, besides, the elastic deformation effect is good. A double sphere has a greater amount of compensation than a single sphere. This product is made by Xinli Company with the new technology of air blowing mould. It is composed of inner rubber layer, reinforcing layer, medium rubber layer, outer rubber layer compound ball and loose sleeve forging low carbon steel flange. It has high pressure resistance, good elasticity and large displacement. The effect of vibration absorption and noise reduction is good, the installation is convenient and so on. It Can be widely used with water supply and drainage, HVAC, fire, compressors, paper, pharmaceuticals, ships, water pumps, fans and other pipes The Tao system.
