PTFE TEFLON lined Stainless steel expansion joint
PTFE Teflon linded Stainless 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.
Excellent performance: PTFE Teflon linded Stainless steel expansion joints 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.
Nominal Diameter (mm/in. ): DN15-DN1600 (NPS1/2-NPS64)
Fatigue frequency: Above 5000 times
Operating temperature: Below 200degree
