High Pressure Temperature Resistance PTFE Rubber Expansion Joint
PTFE rubber expansion joint is based on the original conventional rubber joint, adding PTFE coating lining inside, which can effectively protect the rubber joint from corrosion and medium erosion. For example, strong acid, strong alkali or high-temperature oil, PTFE coating can effectively adhere to the inner wall of the pipeline, prevent the separation caused by medium erosion or pipeline tensile contraction, so that the original mechanical and physical properties of flexible rubber joint are not affected, and can still compensate for pipeline vibration, absorb pipeline displacement and reduce pipeline noise.

Application
Applications of PTFE rubber expansion joint:Due to its good comprehensive performance, PTFE rubber joint is widely used in chemical industry, construction, water supply and drainage, petroleum, light industry, refrigeration, health, water heating, fire protection, electric power and other basic engineering. When concentric decompression rubber compensator is used in high-rise water supply, the pipeline must have fixed support or fixed support, otherwise the product should be equipped with anti pulling equipment. The stress of the fixed bracket or bracket must be greater than the axial force, otherwise the anti pulling equipment should be installed. According to different data, it can be made into a variety of acid, alkali, corrosion and oil resistant media.
