PTFE lined pipes are high-performance composite piping solutions engineered to merge the structural integrity of carbon or stainless steel with the unmatched chemical inertness of Polytetrafluoroethylene (PTFE). Designed for the most demanding industrial environments, these pipes provide a robust barrier against virtually all corrosive media, including strong acids, alkalis, and oxidizing agents, ensuring the safe and efficient transport of aggressive fluids.
By combining a high-strength metal outer shell with a smooth, low-friction PTFE inner lining, these pipelines eliminate the risk of corrosion and contamination. Whether used in cryogenic processes or high-temperature chemical synthesis, PTFE lined pipes offer superior thermal stability and mechanical durability, making them an essential component for high-purity industrial systems seeking to reduce maintenance costs and operational risks.

Frequently Asked Questions
Unlike pure plastic pipes, PTFE lined pipes combine the chemical resistance of PTFE with the mechanical strength of steel, allowing them to handle significantly higher pressures and mechanical stresses while remaining inert.
Yes, they are designed for extreme ranges, typically from –50°C to +200°C, making them suitable for both cryogenic cooling and high-heat chemical reactions.
They are widely used in petrochemical plants, pharmaceutical facilities, semiconductor manufacturing, power plants, and wastewater treatment plants dealing with aggressive media.
We offer a variety of connections including fixed flanges, loose flanges, threaded ends, and welded ends to ensure seamless integration into existing industrial systems.
PTFE is one of the most chemically inert materials known and can withstand nearly all corrosive media, including sulfuric, hydrochloric, and hydrofluoric acids.
The smooth inner surface reduces fluid resistance and prevents the buildup of deposits or scaling, which maintains consistent flow efficiency and simplifies cleaning processes.
