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. This is because PTFE and PFA both have excellent chemical resistance and can withstand relatively high operating temperatures. In addition, PFA and PTFE are non-stick and suitable for use in the food and pharmaceutical industries.
Hanwel provides custom PTFE-coated piping systems in full compliance with applicable industry standards.
- Only virgin paste extruded PTFE of Western European origin is used for the PTFE liner.
- For the PFA liner, virgin molded PFA of Western European origin is used.
- The steelwork comes exclusively from European foundries and is subject to strict requirements.
