Abstract (en)
[origin: EP0027980A1] 1. Process for the scavenging, cleaning, disinfecting and inner coating of a pipe line, in particular a water pipe in a new building, by means of at least one liquid, whereby a pipe-scavenging device is connected between the medium source and the pipe, and the medium is allowed to flow through the pipe line in both directions in order to remove foreign materials, characterised in that the scavenging medium is sucked back through the line in one flow direction and in that an extremely turbulent flow is produced by adding air, by means of which the rest of the foreign materials are removed.
