6.8 Vetter Pipe Sealing Bags CR
Description
Vetter pipe sealing bags CR can be floated into the pipeline with the
liquid flow. The material ensures good resistance against chemicals.
9 Connect the inflation hose(s) to the pipe sealing bag CR and the
single or double controller of the selected pressure level.
9 Attach the spring hooks of the securing lines to the securing lugs.
9 Position the pipe sealing bag CR in the direction of flow into a
shaft and let it float with the liquid flow into the pipe.
9 In doing this, observe the selected diameter and the buoyancy of
the sealing bag.
9 When the sealing bag has been floated in to its full length then
inflation can begin as described in chapter 4.
9 The pipe sealing bag CR is to be fastened during the float-in pro-
cedure and the inflation sequence.
9 Final securing of the bag is only made when the permitted maxi-
mum operating pressure is reached.
