Lining F4 Expansion Joint


Product Details

Steel-Lined PTFE Bellow

Steel-lined PTFE PTFE bellows compensator, also known as expansion joint, expansion joint, is a flexible, thin-walled, transversely corrugated telescopic function consisting of a metal bellows and PTFE. The working principle of the bellows compensator is mainly to use its own elastic deformation function to compensate the axial, angular, lateral and combined displacement of the pipeline due to thermal deformation, mechanical deformation and various mechanical vibrations, which can make up for the shaft when the pipeline is installed. Orientation to radial or radial error, which can solve the problem of expansion and contraction caused by climate change. It has the advantages of large compensation, excellent mechanical performance, good corrosion resistance and long service life. As a kind of vibration absorber, it is installed in the pump. Both ends of the outlet or other high-frequency vibration machinery to reduce or eliminate vibration, improve the service life and sealing performance of the pipeline.
