Product Desciption

PTFE Expansion Joint Vacuum Resistance

We manufacture individually designed PTFE bellows for several applications. They are universally resistant against chemicals and high temperatures and may be modified for special cases of operation, e.g. with metal threaded bushings, flanges and inserts. Bellows differ in their manufacturing processes, functions and loading capacities. They may be used for the compensation of expansion and vibration, as a rod protection in corrosive environmental conditions, for flow of fluids in chemical and pharmaceutical applications and in control and stop valves. They are available with round, angular or sharp folds


Use occasion: It can be used to eliminate the extension of pipeline, container or equipment caused by climate change or swell or displacement caused by other reasons; And used as the vibration-relief device in the access of pump or the two ends of other high frequency machine to reduce or eliminate the vibration; Also used to absorb the deviation between design and actual installation.

Excellent performance: It solves the problem that the metal compensator has bad compensation ability and corrosion resistance to reduce the enterprise cost and promote the production benefits; Besides, it is reliable and has compact structure and high compensation ability, which can extend the using life of pipeline.
