Abstract

Ein Verfahren sowie eine Vorrichtung zum automati­ schen Reinigen und Kontrollieren der Innenoberfläche von Rohren mit Hilfe von Stopfen aus kompressiblem Material, insbesondere aus Filz oder Schaumstoff, umfaßt das Zufüh­ ren der Stopfen, das Einführen in die zu behandelnden Rohre sowie Inspektion nach dem Behandlungsvorgang und die Auslösung von Folgebehandlungen. Vor dem Einführen der mit dem Behandlungsmittel getränktem Stopfen in die Rohre werden die Stopfen zunächst auf ein Durchmesseruntermaß gegenüber dem Rohrinnendurch- messer gepreßt bzw. ver­ dichtet. A method and a device for automati cleaning and checking the inside surface of Pipes using plugs made of compressible material, in particular made of felt or foam, comprises the feed Ren the plug, the insertion into the pipes to be treated as well as post-treatment inspection and the Triggering follow-up treatments. Before introducing the with the treatment agent soaked plug into the pipes the plugs are first reduced to a small diameter pressed or ver against the pipe inside diameter seals.
