Description

Polytetrafluoroethylene corrugated compensator composite property testing device Technical Field The utility model relates to the technical field of corrugated compensator testing, in particular to a polytetrafluoroethylene corrugated compensator composite performance testing device. Background The tetrafluoroethylene corrugated compensator (also called expansion joint) is an industrial instrument for a pipeline system with a strong corrosive medium, and is used for compensating the displacement and the installation deviation caused by expansion and contraction in the pipeline system and reducing the vibration of the pipeline system. The device can eliminate the expansion, thermal expansion or displacement of the pipeline, the container or the equipment and the like caused by climate change or other reasons, and can be arranged at the inlet and the outlet of the pump or at the two ends of other high-frequency machines so as to lighten or eliminate vibration and improve the service life and the sealing performance of the pipeline. The compensation amount of the compensator is inversely related ‌ to the fatigue life, and when the compensation amount demand increases, the fatigue life is significantly reduced.
