PTFE, PFA and FRP lined piping and fitting

Armylor® PTFE or PFA lined piping, pipes, PTFE fittings and PTFE bellows for the chemical industry

The PTFE lined pipes or the PFA lined piping and the PTFE fitting are recognized as the ideal solutions for conveying or processing highly corrosive fluids under severe conditions. The PTFE lining or the PFA liner is chemically inert and resists the majority of corrosive fluids up to 230°C.

Mersen's expertise
