DN150 PN6 Waterproof Resistant Corrosion PTFE Lined Double Ball Rubber Expansion Joint
Product Description:
PTFE lined joint is based on the original conventional rubber joint, adding PTFE coating lining inside, which can effectively protect the rubber joint from corrosion and media erosion. For example, strong acid, strong alkali or high temperature oil, PTFE coating can effectively adhere to the inner wall of the pipe to prevent separation caused by medium erosion or pipe stretching and contraction, so that the original mechanical and physical properties of the flexible rubber joints will not be affected, and can still compensate for pipeline vibration, absorbing pipeline displacement and reducing pipeline noise.
Advantages:
The PTFE lined rubber expansion joint has excellent chemical stability and corrosion resistance. It is one of the best corrosion resistant materials today. Except for molten metal sodium and liquid fluorine, it can resist all kinds of chemicals. It can not change when boiling in aqua regia. It is widely used in all kinds of acid-base and organic solvent resistant.
