RX® PTFE expansion bellows

PTFE bellows are used where the chemical properties of other materials are not sufficient. They have applications in the (petro)chemical industry for the absorption of expansion and/or vibrations and as flexible connections in PTFE and glass-lined piping systems.

Advantages with the use of PTFE bellows:

  • Resistant to chemicals with the exception of fluorine compounds, halogens and liquid alkali metals.
  • The PTFE is collared at the flanges so the metal flanges do not come into contact with the medium.
  • Useable from -70 to +240 °C.
  • With a metal jacket also suitable for high pressures at high temperatures.
  • Insensitive to many movements, material does not so quickly fatigue.
  • Designed as standard with tie rods.
