6.10 Vetter High Pressure Pipe Sealing Bags 6 bar
Description
Vetter high pressure pipe sealing bags 6 bar can be used in pipelines
having a high internal pressure. These pipe sealing bags can be used
up to a counter-pressure of maximum 30 m water column, resp.
3 bar.
The high pressure pipe sealing bag must be positioned along its
whole length on the pipe wall and be secured against catapulting
outwards using suitable means (e.g. support structure).
A pipeline can burst!
It is imperative that the resistance of the pipeline be tested before
using the high pressure pipe sealing bag due to the fact that the
sealing bag produces a maximum area pressure of 6 kg/cm².
9 Connect the inflation hose to the pipe sealing bag and then to
the controller 6 bar (a double controller 6 bar with two inflation
hoses can be used from DN 500 mm onwards).
9 Check for perfect locking of the nipple into the coupling.
9 The air supply can then be turned on (as described in chapter 4).
9 Insert the high pressure pipe sealing bag into the pipeline.
9 Inflate the high pressure pipe sealing bag with controller and in-
flation hose until the permitted operating pressure of maximum
6 bar is reached.
