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. These are similar to the bellows

To accommodate the thermal expansion of any metallic (non-glass) equipment which are connected to the glass pipeline.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.
