PTFE-lined sight glasses by Grayson PTFE Lined Pipe have been engineered to provide superior chemical resistance, making them the perfect choice for corrosive and harsh environments. PTFE lining shields against acids, alkalis and solvents, delivering long-term performance. The sight glasses deliver clear visibility for process observation, which facilitates both operation efficiency and safety. With superior temperature and pressure tolerance they find use in numerous industries, such as chemical, pharmaceutical and petrochemical. Simple to install and service, PTFE-lined sight glasses minimize downtime and maintenance expenses, making them a budget-friendly approach to dependable process monitoring.
A sight glass is a transparent observational device fitted within pipelines or tanks, allowing fluid observation. The inner lining with PTFE provides excellent resistance to chemicals and is, therefore, suitable for corrosive and reactive fluids. It is very resistant to corrosion, contamination, and ensures integrity of the fluid. PTFE-lined sight glasses find widespread applications in chemical processing, pharmaceutical, and petrochemical operations, offering unobstructed visibility even under harsh temperature and pressure conditions. Their heavy-duty construction ensures consistent performance in demanding environments, allowing process monitoring safely and effectively.
