Description

Verfahren zum Umkleiden von Rohren mit Kunststoffschichten Es ist bekannt, Rohre - z. B. Metalirohre - in der Weise mit einer Umkleidung zu versehen, daß Faserstoffe, z. B. Glasfaserstränge, mit Kunststoff, z.B. mit Gießharz, getränkt oder imprägniert und dann auf das Rohr aufgewickelt werden, wonach der Kunststoff aushärtet. Dieses Aushärten erfolgt unmittelbar im Anschluß an den Wickelvorgang.Method of cladding pipes with layers of plastic It is known pipes - e.g. B. Metal pipes - to be provided with a casing in such a way that that fibrous materials, e.g. B. glass fiber strands, impregnated with plastic, e.g. with cast resin or impregnated and then wound onto the pipe, after which the plastic hardens. This hardening takes place immediately after the winding process.

Diese bekannte Art der Umkleidung von Rohren hat den Mangel, daß durch die bis zur Rohroberfläche hindurchtretenden Fasern Poren und Lufteinschlüsse entstehen, die die Entstehung von Korrosionserscheinungen an dem Innenrohr ermöglichen. This known type of casing for pipes has the disadvantage that pores and air pockets due to the fibers passing through to the pipe surface arise that allow the emergence of corrosion phenomena on the inner pipe.

Um diesen Mangel zu beseitigen, wird gemäß der Erfindung vorgeschlagen, auf das zu umkleidende Rohr zunächst eine unbewehrte Grundschicht aus Kunststoff aufzubringen, diese erhärten zu lassen und dann erst in an sich bekannter Weise die bewehrten Kunststoffsohichten als weitere Umkleidung aufzubringen. In order to eliminate this deficiency, it is proposed according to the invention, First, an unreinforced base layer made of plastic is applied to the pipe to be encased to apply, to let this harden and only then in a manner known per se to apply the reinforced plastic layers as further cladding.

Auf diese Weise lassen sich hochwertige Rohrumkleidungen aus Kunststoff herstellen, die frei von allen Poren oder Undichtigkeiten sind. In this way, high-quality pipe linings can be made of plastic produce that are free of any pores or leaks.
