Industries using PTFE-lined sight glasses include chemical processing, pharmaceuticals, food and beverage, petrochemicals, and water treatment for corrosive applications.
PTFE-lined sight glasses have good chemical resistance and are applicable for harsh and corrosive environments. The PTFE lining protects against acids, alkalis, and solvents with long-lasting performance. They provide clear viewing for process monitoring to enhance safety and working efficiency. Having a good temperature and pressure tolerance, they are beneficial across various industries including chemical, pharmaceutical, and petrochemical. PTFE-coated sight glasses are simple to install and to maintain and allow minimal downtime. Their durability and low maintenance cost make them an economical choice for reliable process observation.
A sight glass is a transparent observational device installed on the pipelines or vessels that enables checking of the fluid through sight. The inner lining made of PTFE provides adequate resistance to chemicals and is therefore ideal for corrosive and reactive fluids. It is long-lasting and will withstand contamination without affecting the fluid’s integrity. Commonly used in chemical processing, pharmaceutical, and petrochemical plants, PTFE-lined sight glasses allow uninterrupted vision at extreme pressures and temperatures. Their robust build offers reliable performance under challenging conditions, enabling safe and efficient process observation.
