PTFE lined steel pipes are premium composite piping solutions engineered to merge the unmatched structural integrity of carbon or stainless steel with the superior chemical inertness of Polytetrafluoroethylene (PTFE). Designed for the most demanding industrial environments, these pipes provide an impenetrable barrier against aggressive media, ensuring the safe and efficient transport of high-purity fluids and highly corrosive chemicals.
By integrating a high-performance fluoropolymer lining within a robust metal shell, these pipelines eliminate the risks of corrosion and contamination common in traditional piping. Whether handling strong acids, alkalis, or organic solvents, PTFE lined pipes deliver exceptional thermal stability and low-friction flow, making them an essential component for high-end chemical processing, pharmaceutical production, and semiconductor manufacturing.

Frequently Asked Questions
Unlike plastic pipes, PTFE lined steel pipes combine chemical resistance with the mechanical strength of steel, allowing them to handle much higher pressures and temperatures while remaining inert.
They are ideal for strong acids (sulfuric, hydrochloric), strong alkalis, organic solvents, and highly oxidizing chemicals used in chemical and petrochemical plants.
Yes, PTFE is non-toxic and non-stick, ensuring a hygienic fluid transport environment that prevents contamination, meeting high-purity pharmaceutical standards.
Generally, they operate reliably from –50°C up to +200°C, depending on the specific design and the nature of the transported media.
We offer a variety of connections including fixed flanges, loose flanges, threaded ends, and welded ends to ensure flexible installation for any project.
By eliminating corrosion-related leaks and reducing the frequency of pipe replacements, they significantly lower downtime and long-term maintenance expenses.
