It’s a visual flow indicator with a glass tube and an internal PTFE lining, used to observe fluid flow in corrosive or high-purity applications.
PTFE Lined Tubular Sight Glass: PTFE-lined tubular sight glasses provide an unobstructed vision of fluid movement in pipelines without compromising on the chemical resistance or durability. PTFE lining provides protection from corrosion by severe chemicals and hence finds optimum usage in chemical, pharma and food processing sectors. They are light in weight, easy to install and maintain. They provide safe,e non-reactive measurement in acid alkali and solvent conditions. Resistance to high temperature and pressure adds to the safety and reliability of operation, providing efficient process monitoring under severe conditions.
PTFE lined tubular sight glass is a technologically advanced industrial measuring instrument employed for visual observation of fluid flow through pipelines. It is a clear glass tube which is covered by a protective layer of PTFE (Polytetrafluoroethylene) coating that enhances chemical resistance and prevents corrosion upon usage with corrosive or harmful chemicals. The PTFE coating makes it particularly ideal for use in the pharmaceuticals, chemicals and food processing industries. It provides excellent view of the flowing medium with safety and toughness at high pressure, temperature, and chemically reactive conditions. It promises reliable performance in aggressive applications.
