PTFE lined stailess steel expansion joints
PTFE lined stailess steel expansion joints 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.
PTFE lined stailess steel expansion joints has Excellent performance:
PTFE lined stailess steel expansion jointssolves 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.
