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".
