PTFE Pipes
Corrosion-proof PTFE pipes and tubing for conveying aggressive chemicals, gases and high-purity fluids. Molded and extruded from 100% virgin PTFE for exceptional anti-friction, high-temperature and non-stick performance in chemical, pharmaceutical and food processing.
Features & Applications
PTFE pipes are rigid tubes made from polytetrafluoroethylene (PTFE, CAS RN 9002-84-0), a fully fluorinated polymer whose base resin is produced by fluoropolymer leaders such as Daikin. Their near-universal chemical inertness and roughly 260 °C continuous-service ceiling — consistent with the thermophysical data catalogued in the NIST Chemistry WebBook — make them ideal for transporting corrosive liquids and gases where metal or ordinary plastic pipe would fail.

PTFE Pipes Processing
PTFE Pipes manufactured by processing PTFE into a pipe shape using the extrusion and molding method.
Molded PTFE pipes
The manufacturing process of molded PTFE pipes includes raw material preparation, mold design, molding, sintering, cooling, post-treatment and quality inspection.
Extrusion PTFE pipes
The process of making plunger extruded PTFE pipe includes raw material preparation, heating and plasticizing, extrusion molding, cooling and curing, cutting and trimming, and quality inspection.
Application of PTFE Pipes
PTFE pipes are widely used in the chemical, pharmaceutical and food industries and are suitable for transporting corrosive liquids and gases.
Machine parts
PTFE pipes can be used as machine parts and are widely used as seals, gaskets and bearings in mechanical equipment to enhance performance and reliability.
Gaskets
For sealing of reactors, pipes and valves.
Rubber seal
PTFE pipes can be used as machine parts and are widely used as seals, gaskets and bearings in mechanical equipment to enhance performance and reliability.
Chemical environments
PTFE pipes is used as a component in chemical environments to ensure the safe and efficient transport of chemicals under demanding conditions.
PTFE Pipes FAQ
What sizes and wall thicknesses of PTFE pipe can you supply?
We supply both extruded and molded PTFE pipe across a wide range of inside and outside diameters and wall thicknesses. Molding suits larger diameters and heavier walls, while extrusion suits long, thinner-wall runs. Send us your OD, ID, wall thickness, length and tolerance and we will match the right process and tooling.
What is the maximum operating temperature for PTFE pipes?
PTFE pipes have a continuous-service ceiling of roughly 260 °C and remain serviceable at cryogenic temperatures, so they hold up across almost the entire range seen in chemical and process plants. Allowable pressure falls as temperature rises, so we size wall thickness to your working conditions.
What is the difference between molded and extruded PTFE pipe?
Molded PTFE pipe is formed by compression molding and sintering a billet, which favours larger diameters and thick walls. Extruded pipe is made by plunger (ram) extrusion, ideal for continuous lengths of small- to medium-diameter tube. Both are made from 100% virgin PTFE and share the same chemical and temperature resistance.
Which chemicals can PTFE pipes handle?
PTFE is inert to virtually all industrial acids, alkalis, solvents and oxidisers, which is why PTFE pipe is chosen for the most aggressive media. The rare exceptions are molten alkali metals, fluorine gas and a few highly reactive fluorinating agents. Tell us your medium, concentration and temperature and we will confirm suitability.
Can you supply PTFE-lined pipe and custom parts?
Yes. Beyond solid PTFE pipe we also supply PTFE pipe liners and chemical-resistant linings for steel pipework, plus PTFE machine parts, gaskets and seals. Custom dimensions and free samples are available.
