PTFE/PFA coated pipe sections

For the safe transport of aggressive and corrosive substances, PTFE or PFA coated pipes and pipe sections are the solution. PTFE and PFA both have excellent chemical resistance and can withstand relatively high operating temperatures. PFA and PTFE are also non-stick and suitable for use in the food and pharmaceutical industries.

‍

Hanwel supplies various PTFE- and PFA-coated valves, where we fully comply with applicable industry standards.

‍

For the PTFE liner, we use only virgin paste extruded PTFE of Western European origin.
For the PFA liner, we use virgin molded PFA of Western European origin.
The steelwork comes exclusively from European foundries and is subject to strict requirements.
