6.5 Vetter Bypass Bags 1.5 bar
Description
Vetter 1.5 bar bypass bags can be used for creating a bypass with
defective channels. They can also be used for channel repairs and re-
construction 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.
9 Inflation of the bypass bag can then be made as described in
chapter 4.
