Grayson PTFE Lined Pipe UK is a top-notch manufacturer and supplier of FEP, PTFE, and PFA lined pipes in the UK, providing premium solutions for corrosive and high-temperature use. Our SS 304 PTFE-lined pipes provide unmatched corrosion resistance, while our MS PFA-lined pipes have vent holes for leak detection, providing added safety and reliability. Operating from Midland, we are experts in manufacturing high-quality long-lasting pipes with a perfect finish, providing optimal performance in harsh industrial conditions.
PTFE-lined pipes have a hard chemically inactive coating that is meant to resist pipes and equipment from chemical corrosion and harsh temperatures. Known for their superior chemical resistance, these are the best pipes for handling aggressive chemicals like acids, bases and solvents. With temperature resistance up to 260°C (500°F) these pipes have a smooth, non-stick surface that increases flow efficiency. Made from polytetrafluoroethylene (PTFE) resin and commonly supported by stainless steel PTFE linings provide enduring durability and consistent performance in rugged industrial conditions.
