PTFE bellows and compensators

PTFE Bellow with carbon Steel Flanges (Armylor® process)

PTFE bellows or PTFE expansion joint and PTFE compensators combine the high corrosion resistance of PTFE and its fantastic flexion capability.

Based on these two properties of PTFE, Mersen's products are suitable for use with all chemical products and compensate for repeated thermal expansion in pipelines. They are also widely used to protect equipment against vibration and piping loads.

All products are exclusively made with paste-extruded PTFE for the highest flex life, in virgin quality.
