We at Harry PTFE Lining specialize in top-quality PTFE-lined expansion bellows to take up piping misalignment, vibration, and thermal expansion in key piping systems. These flexible connectors are highly resistant to corrosive chemicals due to the chemically inert PTFE lining. suited to chemical processing, pharmaceutical, food and beverage, power generation, and water treatment industries, our PTFE-lined bellows ensure product purity through avoiding contamination as well as reducing maintenance. Operating efficiently in the wide temperature range of -200°C to 260°C, they are ideally suited to serve aggressive chemicals like sulfuric acid, hydrochloric acid, and chlorine.
A PTFE lined expansion bellow is a flexible piping connector for thermal expansion, vibration, and misalignment absorption in piping systems. It features an inner lining of PTFE (Polytetrafluoroethylene), a chemical-resistant material that’s appropriate for corrosive or high-purity services. The PTFE lining protects the metallic or fabric bellow structure from aggressive fluids and extends its life. These bellows find extensive application in chemical, pharma, and food processes wherein protection against corrosion and contamination is of paramount importance. Bellow flexibility allows axial, lateral, and angular deflections and promotes safe and effective piping system operation under dynamic loading.

PTFE lining increases resistance to chemical corrosion, extending the lifespan of the expansion bellow.
Allows for reliable movement and compensation of thermal expansion or contraction without damage.
Withstands a broad temperature range, making it suitable for extreme environments.
PTFE’s non-stick properties reduce buildup, minimizing cleaning and maintenance needs
A PTFE lined expansion bellow is a flexible connector designed to absorb movement (thermal expansion, vibration, etc.) in pipelines while protecting against corrosive media, thanks to the chemical resistance of the PTFE lining
They are used in industries like chemical processing, pharmaceuticals, food & beverage, and water treatment anywhere aggressive chemicals or highly pure materials are transported.
PTFE (Teflon) is highly resistant to nearly all chemicals, has excellent temperature tolerance (-60°C to +200°C), and offers a non-stick, low-friction surface that prevents buildup and contamination.
Typically, PTFE bellows are designed for low to medium pressure applications. They offer excellent chemical resistance but are less suited for very high-pressure systems compared to metal-only bellows.
They should be installed carefully to avoid over-compression, twisting, or misalignment. Proper anchoring and guides are often needed to ensure the bellow only absorbs the intended movements.
We are the leading Manufacturer and Supplier of PTFE Lined Pipe, Fittings, Flanges, Spool and Valves in Midland, Uk.
