Description

Verfahren zum Auskleiden von Stahl- o. dgl. Rohren mit Überzugsstoffen und hierzu dienende Vorrichtung . .. Gegenstand der Erfindung , ist ein Verfahren zum Auskleiden von Rohren -mit dickflüseigen überzugsstoffen, wie Rostschutzmitteln, mittels einer rotierenden und in asiMer Richtung durch das Rohr wandernden Vorrichtung. Es ist zwar bereits bekannt,. Rohre auf der Innen.seite mit einem schützenden Überzug zu versehen. indem durch das Rohr ein Anstreichkörper mit iMassebehälter gezogen wird, wobei das Anstreichmaterial aus Löchern mittels Preßluft auf die Rohrinnenwandung aufgespritzt und durch einen an dem Anstreichkörper befestigten Bürstenkopf, der durch Preßluft in Rotation versetzt ist. verstrichen wird. Hierbei ist es jedoch nur möglich, verhältnismäßig dünnflüssige Anistrichstoffe aufzubringen.Process for lining steel or the like pipes with coating materials and the device used for this purpose. .. The subject of the invention is a method for lining pipes with thick coating materials such as rust inhibitors, by means of a rotating device moving in an asiatic direction through the pipe. Although it is already known. Tubes on the inside with a protective coating to provide. by pulling a paint body with an iMass container through the pipe is, the painting material from holes by means of compressed air on the inner wall of the pipe sprayed on and by a brush head attached to the paint body, the is set in rotation by compressed air. is elapsed. Here it is, however only possible to apply relatively thin liquid aniseed substances.

Demgegenüber handelt es sich bei der Erfindung darum. Rohre mit einer dicken, bis zu to mm Stärke betragenden- Schicht von Lrberzugsstoffen auszukleiden, die sich in dickflüssigem, breiartigem Zustand befinden, wie es beispielsweise bei Wasserleitungen, welche angres.sive Wässer führen, erforderlich ist. Unimittelbar vor dem Auftragen erfolgt gleichzeitig eine gründliche Reinigung der lzolirwaiiduiig. so aß diadurch ein besonders inniges Anhaften .der Ausfütterungsstoffe ge- währleistet wird.In contrast, this is what the invention is about. Line pipes with a thick layer of up to mm thick layer of coating materials that are in a viscous, mushy state, as is necessary, for example, in water pipes that carry aggressive water. Immediately before application, the lzolirwaiiduiig is thoroughly cleaned at the same time. so diadurch ate a particularly close attachment .the Ausfütterungsstoffe is guaranteed.

Dementsprechend besteht dabs-..neue Ver-; fahren aus drei unmittelbar aufeinanderfolgenden Einzelvorgängen, nämlich: r. Reinigen de:- Rohrwandungen, z. Auftragen der Isoliermasse, 3. Verstreichen den Isoliermasse und Nach-;.streiche4i; Diese drei Vorgänge werden in einem einzinnen Arbeitsgang durchgeführt. Diese Kombination der drei eben genannten und jede für sich allein bekannten Maßnahmen bildet das Wesen der Erfindung.Accordingly, there is dabs - .. new ver; drive out of three immediately successive individual processes, namely: r. Cleaning de: - Pipe walls, e.g. Applying the insulating compound, 3. Spreading the insulating compound and then -;. Streak4i; These three processes are carried out in a single operation. This combination of the three measures just mentioned, each of which is known on its own, forms this Essence of the invention.

Eine zur Ausführung des neuen Verfahrens geeignete Vorrichtung ist in der Zeichnun.g schematisch im Quer- und Längsschnitt dargestellt. Sie besteht aus den Bürsten@a zum Reinigen der Rohwandung, den Auslaufstutzen b, die die Isoliermassen auf die Rohrwand werfen, den Streichern. c, zum Verstreichen des Auftrags und zum Nachstreichen, der Trommel d, die die Isolierstoffe enthält, der Welle f, die die ganze Vorrichtung trägt. Der Arbeitsvorgang für Auskleidung von Rohrei, z. B. mit Asphaltbitumen, gestaltet sich folgendermaßen: Das auszufütterndie Rohr n «wird auf Böcke oder Rollen gelegt, die Schleudervorrichtung an einem Rohrende eingeführt, in schnelle Umdrehung versetzt und .in axialer Richtung durch das Rohr gezogen oder geschoben. , . Die Bürsten a, die AulsJaufstutzen b und die Putzer c können 'zweckmäßig in axialer Richtung derart lrintereinanderlIegend angeordnet sein, (laß zuerst die Bürsten a angreifeii und die Rohrwandung reinigen, wobei anhaftender Zunder und etwa vorhandene AnTostungen -abgekratzt und z. B. durch 'Druckluft herausgeblasen werden. Unmittelbar hinter den .durch die Federre e angepreßten Bürsten a folgen die Auslaufstutzen b, die das Isoliermaterial aus der Trommel d erhalten und auf die Rohnva:ndung werfen. In kurzem Abstand: nach den Auslaufstutzen b folgen die Putzvorrichtungen c. die die Aufgabe -haben, das auf die Rohrwand geschleuderte Isoliergut gründlich zu verstreichen und gegebenenfalls einen dünnen DeckanstT,ich aufzubringen.A device suitable for carrying out the new method is shown schematically in cross-section and longitudinal section in the drawing. It consists of the brushes @ a for cleaning the raw wall, the outlet nozzles b, which throw the insulating compound onto the pipe wall, the strings. c, for spreading the application and for repainting, the drum d, which contains the insulating materials, the shaft f, which carries the entire device. The process for lining raw egg, e.g. B. with asphalt bitumen, is designed as follows: The pipe to be fed out is placed on trestles or rollers, the centrifugal device is inserted at one end of the pipe, set in rapid rotation and pulled or pushed in the axial direction through the pipe. ,. The brushes a, the outer spigots b and the cleaners c can be 'conveniently arranged one behind the other in the axial direction (first let the brushes a attack and clean the pipe wall, whereby adhering scale and any smudges that may be present are scraped off and, for example, by' Immediately behind the brushes a, which are pressed on by the spring brakes, are the outlet nozzles b, which receive the insulating material from the drum d and throw it onto the pipe vault. At a short distance: after the outlet nozzles b, the cleaning devices c the task -have to spread the insulation material thrown onto the pipe wall thoroughly and, if necessary, to apply a thin cover layer.

Das Rohr selbst kann sich beim Durchgang der Schleudenorrichtung entweder in Ruhelage befinden oder in. langsamer gegenläufiger Umdrehung. Ist 4etztere& gier Fall, so ergibt sich die Möglichkeit, auf mechannschem Wege gleichzeitig auch die äußere Rohrwandung zu säubern und ein Rostschutzmittd auf diese aufzutragen.The tube itself can either move through the sling device are in rest position or in. Slow counter-rotating rotation. Is 4 last & greed case, then the possibility arises, in a mechanical way at the same time To clean the outer pipe wall and to apply a rust protection agent to it.

Die Hauptvorteile das .reuen Verfahrens bestehen in folgendem: i. Sorgfältigge Säuberung der Wandung des Rohres, die für einen Rostschutz unerläßlich ist, 2. Eindringen des aufschleuderten Isoliergutes in die feinsten Poren das Eisens, 3. Gründliches Verstreichen der aufgetragenen Schicht durch die Putzvorrichtungen, so daß eine innig zummmenhängende Isolierschicht i entsteht, die gegebenenfalls noch durch einen dünnen Nachanstrich gedeckt wird.The main advantages of the good practice are as follows: i. Careful cleaning of the wall of the pipe, which is indispensable for rust protection, 2. Penetration of the thrown-on insulating material into the finest pores of the iron, 3. Thoroughly spreading the applied layer through the cleaning devices, so that an intimately connected insulating layer is created, which may still be is covered by a thin top coat.
