7. VETTER Bypass Bags 1.5 bar FS
7.1 Description
Vetter bypass bags 1.5 bar can, for example, be used for purpo-
seful detour or for pumping out extinguishing water. They can
also be used for channel repairs and reconstruction as two-sided,
temporary blocking with conduction and pressure relief from the
incoming pipeline to the outgoing pipeline.
9 Please observe the permitted maximum counter-pressure of
5 m water column, resp. 0.5 bar, when using bypass bags.
9 Connect the inflation hose, 1.5 bar, to the bypass bag and the
single controller, 1.5 bar fitting.
9 Insert the bypass bag along its full length into the pipeline
and secure it against catapulting out using suitable devices,
e.g. a structure support. Inflation of the bypass bag can then
be made as described in chapter 4.
