Zur Prüfung der Dichtheit der auf der Rohrleitung gebildeten Umkleidung kann man auf der Umkleldungsfolie auf der der Rohrleitung zugewendeten Seite einen dünnen selbstklebenden Metallstreifen vorsehen. Die Prüfung kann mittels einer Vorrichtung für elektrische Glimmentladungen erfolgen, wobei der Gleitkontakt dieser Vorrichtung entlang der Verbindung der Bedekkung gleitet und wobei das anhaftende Metallband mit der Erde verbunden ist. laTo check the tightness of the cladding formed on the pipeline, you can use the wrapping foil Provide a thin self-adhesive metal strip on the side facing the pipeline. the Testing can be done by means of a device for electrical glow discharges, the sliding contact this device slides along the connection of the cover and with the adhering metal band connected to the earth. la
Die Fig. 2 zeigt eine Vorrichtung, mit der man auf der Rohrleitung eine Wärmeisolierung bildet durch Expandieren eines thermoplastischen Harzes, das man in einer Form 9 schäumen läßt, die auf der Rohrleitung gleitet zugleich mit der Anordnung der Rolle 4 und der Einlaufrinne 6.Fig. 2 shows a device with which one on the Thermal insulation is formed by expanding a thermoplastic resin that is incorporated into a pipe Form 9 can foam, which slides on the pipeline at the same time with the arrangement of the roller 4 and the inlet channel 6th
Das flüssige Harz wird bei 10 und 11 mit der Rohrleitung In Berührung gebracht. In der Zone 12 beginnt es zu expandieren; seine Expansion ist vollständig beendet bei 13, und es ist schon halb hart. Bei 14 ist das expandierte Harz genügend starr, um mit der Umkleidungsfolie bedeckt werden zu können.The liquid resin is at 10 and 11 with the pipeline Brought in touch. In zone 12 it begins to expand; its expansion is completely finished at 13, and it's already half hard. At 14 the expanded resin is sufficiently rigid to adhere to the liner to be covered.
Bei der in Fig. 3 dargestellten Variante findet die Expansion der Harzes unmittelbar an der Stelle statt, wo die Umkleidung gebildet wird. Das flüssige Harz wird zugeführt bei 15, bei 16 ist es im kremigen Zustand, lind bei 17 beginnt es zu expandieren. Das Harz 1st vollständig expandiert bei 18 und füllt den Zwischenraum zwischen der Rohrleitung 1 und der gebildeten Röhre 19 aus. In diesem Falle dient die Einlaufrinne 6 einerseits zur BiI-dung der Bekleidungsröhre 19 und andererseits zur Herstellung des notwendigen mechanischen Widerstandes zur Aufnahme des Druckes von der Expansion des Schaumes.In the variant shown in Fig. 3, the expansion of the resin takes place directly at the point where the casing is formed. The liquid resin is fed in at 15, at 16 it is in a creamy state, lind at 17 it begins to expand. The resin is fully expanded at 18 and fills the gap between the pipe 1 and the tube 19 formed. In this case, the inlet channel 6 serves on the one hand for formation the clothing tube 19 and on the other hand to produce the necessary mechanical resistance to absorb the pressure from the expansion of the foam.
Die In Fig. 4 dargestellte Vorrichtung zur kontinuierlichen Herstellung der Wärmeisolierung 2 und der äußeren Umkleidung umfaßt einen Schlitten 20, der mit Laufrollen 21 bis 22 versehen 1st, die in Berührung mit der Rohrleitung 1 sind. Dieser Schlitten ist selbstfahrend und hat einen Motor 23, der unter Zwischenschaltung eines Vorgeleges 24 eine der Rollen 21 antreibt. Das Chassis 25 des Motors 1st auf dem Schlitten montiert unter Zwischenschaltung von Schraubenhalterungen 26, die die Regelung seiner Stellung in der Höhe entsprechend dem Durchmesser der Rohrleitung 1 gestatten. Zu demselben Zweck sind die unteren Rollen 22 ihrerseits auf regelbaren Halterungen 27 montiert, die eine Veränderung ihrer Stellung zulassen.The device shown in Fig. 4 for continuous Manufacture of the thermal insulation 2 and the outer cladding comprises a carriage 20 with rollers 21 to 22 are provided, which are in contact with the pipeline 1. This sled is self-propelled and has a motor 23 which drives one of the rollers 21 with an intermediate gear 24. The chassis 25 of the motor is mounted on the slide with the interposition of screw brackets 26, which the Allow control of its position in height according to the diameter of the pipe 1. To the same Purpose, the lower rollers 22 are in turn mounted on adjustable brackets 27 that can change their Allow position.
Auf dem Schlitten 20 ist eine rotierende Scheibe 28 montiert, die Rollen 29 mit isolierendem Band 30 tragen. Diese Scheibe wird angetrieben durch den Motor 23 unter Zwischenschaltung einer Transmission 31, die an ihrem Ausgang ein Ritzel aufweist, das in Eingriff 1st mit einem innen verzahnten Kranz an der Scheibe.A rotating disk 28, which carries rollers 29 with insulating tape 30, is mounted on the carriage 20. This disc is driven by the motor 23 with the interposition of a transmission 31, which is attached to her Output has a pinion which meshes with an internally toothed ring on the disc.
Die Rolle 4 mit der Folie 3, die die Bekleidung der wärmeisolierten Rohrleitung bilden soll, ist auf dem Schlitten 20 montiert. Die Folie 3 läuft zwischen Führungsrollen 32 bis 33 durch und wird in die der Führung dienende Einlaufrinne 6 eingeleitet, die an dem Schlitten mittels angelenkter Stangen 34, 35, 36 befestigt ist. Durch kontinuierliche Weiterbewegung auf der Rohrleitung 1 bewirkt der Schlitten 20 zugleich die Bildung der Wärmeisolierung 2 und die Bildung der äußeren Umkleidung 19. Ein von einer Rolle 38 kommendes KJebband 37 wird auf die Ränder der Umkleidung aufgebracht mittels einer Rolle 39, wobei der Support 40 für die Rolle 38 und die Andruckrolle 39 an der Einlaufrinne 6 befestigt sind. Es ist eine Feder 41 0. dgl. vorgesehen, um die Rolle 39 gegen die Röhre zu drücken.The roll 4 with the film 3, which is to form the cladding of the heat-insulated pipeline, is mounted on the slide 20. The film 3 runs through between guide rollers 32 to 33 and is introduced into the inlet channel 6 which is used for guidance and which is attached to the carriage by means of articulated rods 34, 35, 36 . By continuously moving on the pipeline 1, the carriage 20 simultaneously causes the formation of the thermal insulation 2 and the formation of the outer cladding 19. A KJebband 37 coming from a roll 38 is applied to the edges of the cladding by means of a roller 39, the support 40 for the roller 38 and the pressure roller 39 are attached to the inlet channel 6. A spring 41, the like, is provided to press the roller 39 against the tube.
In F i g. 5 1st die Zone der Bedeckung durch das Kiebband 37 auf der Bekleidung 3 dargestellt.In Fig. 5 the zone of coverage by the adhesive tape 37 on the cladding 3 is shown.
Bei der In Flg. 6 dargestellten Ausführung werden die beiden Kanten der Folie 3 durch Verschmelzung verschweißt. Diese Verschmelzung wird bewirkt mittels einer Vorrichtung, die an der Einlaufrinne 6 befestigt ist und sich mit dem Schlitten 20 (in dieser Figur nicht dargestellt) fortbewegt und die eine Luftzuführung 42, durch eine Leitung 44 gespeiste Heizwiderstände 43 und ein Heizelement 45 umfaßt, wobei die Verschmelzung der beiden Kanten der Umkleidung durch heiße Luft erfolgt, die dem Heizelement durch die Einrichtung 43 zugeführt wird. Die Verschweißung wird vervollständigt durch den Andruck einer Rolle 46.At the In Flg. 6 shown are the both edges of the film 3 welded by fusing. This amalgamation is effected by means of a device which is attached to the inlet channel 6 and which is connected to the slide 20 (not shown in this figure) moved forward and the one air supply 42, fed by a line 44 heating resistors 43 and a Comprises heating element 45, the two edges of the casing being fused by hot air, which is fed to the heating element by the device 43. The weld is completed by the Pressure of a roller 46.
