PTFE bellows and compensators

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.

Based on these two properties of PTFE, Mersen's products are suitable for work with all chemical products and compensate repeated thermal expansion in pipelines.

They are also widely used to protect equipment against vibration and piping loads.
