The standard connection types for PTFE-lined sight glasses include flanged, threaded, tri-clamp, and socket-weld, with selection based on specific application needs.
PTFE-lined sight glasses exhibit good chemical resistance and can be used for severe and corrosive conditions. PTFE lining protects against acids, alkalis, and solvents and exhibits long-lasting performance. We offer a clear vision for process observation to enhance safety and operational efficiency. With high tolerance to pressure and temperature, they are helpful across various industries including chemical, pharmaceutical, and petrochemical. PTFE-lined sight glasses are simple to install and maintain and offer low downtime. Their ruggedness and low maintenance costs make them a cost-effective choice for consistent process monitoring.
A sight glass is a transparent viewing assembly installed on the pipelines or vessels that enables fluid checking by visual inspection. The inner PTFE lining has excellent chemical resistance and is therefore appropriate for corrosive and reactive fluids. It is resistant to contamination and is durable, which means the integrity of the fluid is preserved. Used extensively in petrochemical, pharmaceutical and chemical processing industries, PTFE-lined sight glasses offer unobstructed visibility under high pressures and temperatures. Their robust construction offers reliable performance in harsh conditions, enabling safe and efficient process monitoring.
