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

Since 1964, Mersen has supplied an extensive range of  PTFE piping or PFA pipes and PTFE fittings to in excess of a thousand chemicals producers world wide.

Mersen is a manufacturing expert in the 3 lining technologies:

  • Extrusion of PTFE fine powders
  • PFA injection
  • PTFE isomoulding

Armylor® PTFE lined pipes and PFA piping provide several advantages:

  • High resistance to thermal shock
  • PTFE / PFA seamless linings
  • Easy installation, as no gasket required  
  • Low natural permeability rate
  • Possibility for custom made pieces with complex geometry

DN1050 mm PTFE lined bellows

Mersen Pagny recently designed and manufactured a batch of several DN1050 mm PTFE lined bellows for a major player in French chemistry. Mersen offers two ranges of bellows: a standard range with 3 and 5 convolutions and a vacuum-resistant range with 3 convolutions. The diameters range from DN20 to DN1050mm.
