1.2 Correct handling and usage
Vetter pipe sealing- and bypass bags must, depending on the pur-
pose of the task, only be inflated with compressed air to the corre-
sponding pressure level using original inflation fittings.
Inflation with inflation fittings from another manufacturer is clas-
sified as contrary to the regulations for correct use.
They are exclusively used for blocking the intended pipes, for leak
sealing testing of pipelines and for construction of a bypass.
Any other application or use going beyond this is classified as
contrary to the regulations for correct use.
