The PTFE lined double ball joint is based on the original conventional rubber joint, and the PTFE coated lining is added inside to effectively protect the rubber joint from corrosion and medium erosion. For example, strong acid, strong alkali, or high-temperature oil, PTFE coatings can effectively adhere to the inner wall of pipelines, prevent separation caused by medium erosion or pipeline stretching and contraction, so that the original mechanical and physical properties of flexible rubber joints are not affected, and can still compensate for pipeline vibration, absorb pipeline displacement, and reduce pipeline noise.
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.
