PTFE/PFA special jacketed piping

double wall pipe PTFE coating Mersen

Carbon steel expansion bellows and flanges with a PTFE coating (Armylor® process)

PTFE bellows and compensators combine the high corrosion resistance of PTFE and its fantastic flexion capability.
Jacketed pipes & fittings are lined with PTFE or PFA using

  • PTFE paste extrusion,
  • PTFE isostatic molding for large tees and elbows, and
  • PFA injection molding for smaller pieces.

    DIN and ANSI standard

      They are available in both DIN and ANSI standard and are proposed in both virgin or antistatic material. Based on standard pipes and fittings items, each component is covered by a double jacket steel housing.

      The double jacket is equipped with 1/4” or ½” NPT couplings or flanged DN20 (3/4”) or DN25 (1”) nozzles for the alimentation of calorific fluid.

      An original system allows the heating up to the back side of the flanges, so that all parts of the piping are covered.
