PTFE lined Piping Systems

PTFE lined pipe parts and PFA lined fittings to prevent corrosion

For the safe transport of aggressive and corrosive substances such as chlorine and H2SO4, PTFE lined piping components and PFA lined fittings are the right solution. PTFE and PFA both offer excellent chemical resistance and can withstand relatively high operating temperatures. PFA and PTFE are non-stick and suitable to be applied in the food industry and pharmacy.

Hanwel develops and offers customized PTFE lined piping systems which are fully in accordance with prevailing industry standards.

  • For the PTFE liner we use virgin paste extruded PTFE raw material originating from Western-European origin only
  • For the PFA liner, we use virgin molded PFA originating from Western European origin only
  • Our steelwork originates exclusively from European foundries and is subject to strict quality requirements.
