PTFE rubber joints are widely used in connection with pumps and valves, pipelines with large vibration, pipelines with strong acid and alkali resistance with frequent changes in heat and cold.
Working Principle:
The inner PTFE (polytetrafluoroethylene) lining provides corrosion resistance to the medium, while the outer rubber layer provides elastic compensation and vibration damping.
Functional Summary:
Extremely strong corrosion and chemical resistance
Simultaneously provides expansion, contraction, and vibration damping capabilities
Extends the lifespan of the piping system
Application Scenarios:
Chemical plants
Acid and alkali conveying pipelines
Pharmaceutical and fine chemical industries
Environmental protection projects
