PTFE Bellows (Glass to Metal)



These bellows are used in installation of glass equipment for following purposes :

  • to minimize the transfer of vibrations from the rotating equipments which are connected to the glass assembly.
  • to accommodate the thermal expansion of any metallic (non-glass) equipment which are connected to the glass pipeline.

These are similar to the bellows for glass-to-glass in construction, but having a adaptor bellow flange at one end. Generally this adaptor flange is supplied undrilled so that it can be drilled as per the configuration of mating flange. However, this adaptor bellow flange can be supplied drilled as per “Table E”, Table F” or “ASA 150” standards if specified.
