PTFE Lined Tubular Sight Glass: PTFE-lined tubular sight glasses give an unrestricted view of fluid flow in pipelines while offering superior chemical resistance and durability. The PTFE lining offers resistance to corrosion by aggressive chemicals and is thus best used in chemical, pharma and food processing industries. They are light in weight easy to install and require minimal maintenance. They provide secure non-reactive observation in acid alkali and solvent systems. Their resistance to high temperature and pressure improves operating safety and reliability, providing effective process monitoring in challenging conditions.
PTFE lined tubular sight glass is a high-tech industrial instrument used for visual observation of the flow of fluids in pipelines. It is a transparent glass tube surrounded by a protective PTFE (Polytetrafluoroethylene) coating which improves chemical resistance and avoids corrosion when used with aggressive or dangerous chemicals. The PTFE coating makes it especially suitable for the pharmaceuticals, chemicals and food processing industries. It offers great visibility of the flowing medium with safety and durability under high pressure, temperature, and chemically reactive conditions. It guarantees consistent performance in harsh applications.
