Abstract The new process for the sealing and internal repair of systems of laid conduits having a small internal diameter operates with sealing by blocking the leak by means of an introduced sealing agent and with internal repair by means of abrasive blowing out and recoating of the conduit. The method comprises either the blowing in of a sealant containing a very finely ground water-swellable bentonite and/or a hydraulically disintegratable plastic dispersion dry preparation as well as inert additives, and the charging and holding of the conduit with a steam and air mixture having an excess pressure of > 2 bar or filling and perfusion of water in/through the conduit or the introduction of inert blocking material by means of a stream of water. The installation comprises, among other things, a compressed air distributor (3.02) with air supply conduit (3.04) and air outlet conduits (3.05 to 3.07), the conduits carrying valves and pressure measuring devices (3.15 to 3.27) among other things and the corresponding wet installation. With these apparatuses, it is possible to determine both the pressure drop in individual conduit lines at various p and m and also to drive the automated repair programmes.
