PTFE compensator, can be called as bellow, also known as expansion joint, it can be used to eliminate channels such as container and equipment because of climate change caused by stretching or other reasons leading to the thermal expansion or displacement. PTFE compensator is one type of relief vibration. It can pump installed in the import and export of high-freqency or other machinery at both sides to reduce or eliminate the vibration and improve the life of pipes and sealing performance. Resolve the problem that the metal compensator can not solve, reduce the business costs and improve the production efficiency. In addition, PTFE compensator can be used to absorb the actual design and installation deviation. Working with reliable, compact and strong compensation to all kinds of medium and long service life of corrosion and other advantages.
