At Harry PTFE Lining, a reputable UK manufacturer and supplier of MS PTFE-lined pipes, we provide affordable, high-performance piping solutions for chemical processing, pharmaceutical, petrochemical, and other demanding industries. Our products are carefully designed to provide long-term protection, minimize maintenance costs, and ensure safe, reliable fluid transport. Taking the mechanical strength of mild steel (MS) and the unparalleled chemical durability of PTFE to advantage, our lined pipes are designed for high performance and durability. The structural strength of MS serves as the inner core, while the PTFE lining provides excellent resistance to corrosive chemicals, extreme heat, and abrasive media. With this multi-layered pipe design, ours stands out to be the most suitable to withstand even the most stringent industrial environments.
An MS PTFE-lined pipe is a mild steel (MS) pipe that is internally lined with polytetrafluoroethylene (PTFE) — a high-performance fluoropolymer that is well known for its excellent chemical resistance as well as non-stick properties. The PTFE lining serves as a barrier, protecting the steel from corrosive substances and making the pipe suitable for conveying aggressive acids, bases, and solvents in chemical processing, pharmaceutical, and food production industries. The PTFE offers a smooth, inert inner surface, while the MS outer coating offers mechanical integrity and structural stability. This combination is a piping system that features superior durability, enhanced safety, and extended lifespan — even under the most harsh conditions where pipes made of metal or plastic would deteriorate quite rapidly.

Superior protection against corrosive chemicals.
Reduces friction and enhances flow efficiency.
Withstands high temperatures (up to 260°C) and high pressures.
More affordable than expensive alloys, offering similar performance.
An MS PTFE lined pipe is a mild steel (MS) pipe internally coated with polytetrafluoroethylene (PTFE) to combine mechanical strength with superior chemical resistance.
The PTFE lining protects the steel from corrosion by aggressive chemicals, extending the pipe’s life and maintaining fluid purity.
They are widely used in chemical processing, pharmaceuticals, food processing, petrochemicals, and other industries that handle corrosive or hazardous fluids.
They offer excellent chemical resistance, high durability, low maintenance, a smooth non-stick surface, and reliable performance under extreme conditions.
Yes, PTFE can withstand high temperatures (up to around 260°C), making these pipes suitable for hot, corrosive, or aggressive media transport.
