PTFE lined flanges are industrial pipe flanges with lining of the high-performing fluoropolymer, i.e., Polytetrafluoroethylene (PTFE). It possesses excellent chemical resistance, is non-adhesive, and has thermal stability. PTFE lined flanges are used in corrosive and poisonous chemical treatment systems to join pipes and equipment. The PTFE lining acts as a shield between the corrosive fluid and the metal flange to avoid corrosion, contamination and leakage. PTFE lined flanges are used in various industries including chemical processing, pharmaceuticals, food and beverage, and oil & gas. They come in a variety of types including slip-on, weld neck, blind, and lap joint flanges, and are also custom-made according to specific requirements. They are solid and reliable and hence must be used for risk-free handling of fluids.

Ideal for handling aggressive chemicals and corrosive media
Ensures tight sealing and prevents fluid leakage
Available in various flange types and sizes to fit specific applications
Minimizes downtime and reduces overall maintenance costs
A PTFE lined flange is a metal flange coated with a corrosion-resistant plastic lining (such as PTFE, FEP, or PFA) to protect against chemical damage and ensure a clean flow.
Yes, lined flanges come with pressure and temperature ratings based on the liner material and base metal, typically up to 150 psi and 200°C (392°F).
PTFE lined flanges are highly durable, with a long lifespan, particularly in harsh chemical environments, when properly installed and maintained.
Installation is similar to standard flanges, but extra care is needed to avoid damaging the liner. Use torque-controlled tightening and ensure compatible gaskets to preserve the lining integrity.
Lined flanges should be used in piping systems handling corrosive, high-purity, or reactive chemicals to ensure safe, durable, and effective operation.
