A variety of stirrer & stirrer drives are available to use glass vessels as agitated reaction equipment
The couplings used with glass equipment are important from two main points of view :
1.They must ensure the effective seal of the joint.
2.They should not induce any undue stress in the glass.
3.They must be reliable in all service conditions.
In this section we have covered couplings to join glass components together as well as to join glass component with a other metal equipment.
PTFE bellows are available for normal and vacuum applications together with flanges to connect them to glass or non-glass equipment.
COMPLETE COUPLINGS
A complete coupling is a set of two backing flanges with insert and nut-bolts. complete set of f l a n g e s require to make a joint & standard one are available in Cast Iron. Also available in other MOC like Stainless Steel 304 & 316, Siliumin.

PTFE BELLOWS - GLASS TO GLASS
These bellows are used in installation of glass equipment for following purposes :
- To provide safe branching of pipelines from the main glass equipment.
- To accommodate odd degrees and variation in length.
Bellows are supplied along with required bellow flanges and nut-bolts
Distance - locking bolts are provided to avoid excessive compression or contraction of the bellow. Gaskets are not required where bellows are used. For drilling details, refer "Bellow flanges"
Line bellows
These can withstand a temperature of 200 C under normal atmospheric conditions.

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 a r e connected to the glasspipeline.
These are similar to the bellows for glass-to-glass in construction, but having 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.
