Product Description

PTFE Bellows to Compensate for Mechanical and Thermal Changes
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.

Special pieces of specific or non standard size can be manufactured on request.
