Abstract

Pipes are lined with film tubing by inflating the film while turning it inside out into the pipe and pressing it against the i.d. of the pipe; before pressing the film inside however a tubular fabric is inserted into the pipe, the film is pressed inside this fabric, and the fabric is pressed against the pipe i.d. The fabric is pref. knitted or woven frompolyester threads. In the first action a tubular fabric (3) is drawn through the pipe (1) by means of a windlass. The film tubing (4) is coated with adhesive and then introduced into the pipe (1) by an air draught by turning it inside out. The fabric (3) thus lies between the film tubing (4) and the wall of the pipe (1). ADVNATAGE - The procedure makes a lined pipe which can withstand high internal pressure.

Description

Die Erfindung bezieht sich auf ein Verfahren zum Auskleiden von Rohren mit einer schlauchförmigen Folie, bei dem die Folie mittels eines Druckmittels im Wege des Umstülpens in das Rohr und an die Rohrinnenwand gedrückt wird.The invention relates to a method for lining of tubes with a tubular film, in which the Foil by means of a pressure medium by turning inside out the pipe is pressed against the inner wall of the pipe.

Bei einem bekannten Verfahren dieser Art wird die Folie (aller­ dings unter Zwischenschaltung einer Klebemasse) unmittelbar gegen die Rohrinnenwand gepreßt.In a known method of this type, the film (all However, with the interposition of an adhesive) immediately against pressed the inner tube wall.

Der Erfindung liegt die Aufgabe zugrunde, das eingangs er­ wähnte Verfahren derart auszubilden, daß das ausgekleidete Rohr besonders hohen Innendrucken ausgesetzt werden kann.The invention has for its object that he initially imagined procedures in such a way that the lined Tube can be exposed to particularly high internal pressures.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß vor dem Eindrücken der Folie in das Rohr ein schlauchförmiges Gewebe in das Rohr eingebracht wird und daß die Folie in das Gewebe eingedrückt wird, wobei letzteres gegen die Rohr­ innenwand gedrückt wird.This object is achieved in that before pressing the film into the tube is a tubular one Tissue is introduced into the tube and that the film in the tissue is pressed in, the latter against the tube inside wall is pressed.

Auf diese Weise wird erreicht, daß das fertig ausgekleidete Rohr höheren Innendrucken ausgesetzt werden kann als ein Rohr, das nicht mit einem Schlauchgewebe versehen ist.In this way it is achieved that the fully lined Pipe can be subjected to higher internal pressures than a pipe, that is not provided with a tubular fabric.

In der Regel wird das bekannte Verfahren derart geführt, daß sich zwischen Schlauch und Rohr eine Klebemasse befindet. Vorzugsweise gilt das auch für das erfindungsgemäße Verfahren.As a rule, the known method is carried out in such a way that there is an adhesive between the hose and the pipe. This preferably also applies to the method according to the invention.

Weitere Einzelheiten der Erfindung ergeben sich aus der Zeichnung. Darin zeigen:Further details of the invention emerge from the drawing. In it show:

Fig. 1 einen ersten Verfahrensschritt und Fig. 1 shows a first process step and

Fig. 2 einen zweiten Verfahrensschritt. Fig. 2 shows a second process step.

In beiden Figuren ist mit 1 ein Rohr bezeichnet.In both figures, 1 denotes a tube.

Wie der Fig. 1 zu entnehmen ist, wird mittels einer Winde 2 in das Rohr 1 ein schlauchförmiges Gewebe 3 hineingezogen.As can be seen in FIG. 1, a tubular fabric 3 is drawn into the tube 1 by means of a winch 2 .

Dann wird (siehe Fig. 2) eine schlauchförmige Folie 4, die vor­ her mit Kleber versehen worden ist, von rechts her mittels Luft in das schlauchförmige Gewebe 3 bzw. in das Rohr 1 im Um­ stülpverfahren gedrückt. Dabei legt sich das schlauchförmige Gewebe 3 zwischen die Folie 4 und das Rohr 1.Then (see Fig. 2), a tubular film 4 , which has been provided with adhesive before, from the right by means of air in the tubular fabric 3 or in the tube 1 in order to put down. The tubular fabric 3 lies between the film 4 and the tube 1 .
