FOR SEALING ON TESTS ON DOMESTIC PIPELINES
Blocking as well as the test procedure are carried out exclusively from the inspection shaft. Using as inflation hose and a feed hose, the sealing bag is pushed in until it reaches the mouth of the main sewage channel.
The test sealing bag is positioned so that it is just in front of the inspection shaft.
The special short design of the pipe sealing bag, as well as the rounded "tip", increase the bending characteristics. In addition to this, the other end of the sealing bag is fitted with a spherical head which enables an effortless return of the bag via a sleeve offset.
Easy inflation of both bags is made with a foot air pump via the inflation hose and the feed hose.
All pipe sealing and testing bags have a BSP thread
