PTFE Lined Tubular Sight GlassPTFE-lined tubular sight glasses provide unobstructed visual observation of the flow of fluid in pipelines combined with excellent chemical resistance and life. The lining of PTFE provides protection against corrosion due to aggressive chemicals and is accordingly best suited in chemical, pharma and food processing applications. They are weightless easy to fit and maintain and need negligible maintenance. They ensure safe non-reactive monitoring in acid alkali and solvent systems. Their high temperature and pressure resistance enhance operating reliability and safety, and offer efficient process monitoring in extreme conditions.
PTFE lined tubular sight glass is a technologically advanced industrial device utilized for visual monitoring of the flow of liquid in pipelines. It is a clear glass tube encased within a protective PTFE (Polytetrafluoroethylene) coating to enhance chemical resistance and prevent corrosion when utilized with aggressive or hazardous chemicals. The PTFE coating makes it particularly acceptable for use in the pharmaceuticals, chemicals and food processing industries. It has excellent visibility of the flowing medium with safety and long life under high pressure, temperature, and chemically reactive conditions. It promises constant performance in demanding applications.
