Description

Verbundrohr aus Metall und KunststoffComposite pipe made of metal and plastic

Die Neuerung bezieht sich auf ein Rohr, dessen Außenmantel aus Metall und dessen Putter aus einem thermoplastischen Kunststoff, wie z.B. aus Polyvinylchlorid oder Polyäthylen besteht. Durch die Vereinigung solcher verschiedenartiger Baustoffe gelingt es, dem Verbundrohr Eigenschaften zu geben, die sein Anwendungsgebiet beträchtlich erweitern. Während das Metallrohr die Festigkeit des Kunststoffesvesentlich erhöht und das letztere gegen mechanische Beanspruchung schützt, erfährt das erstere durch das Kunststoffrohr einen im allgemeinen genügenden Schutz gegen die Angriffe chemischer Wirkstoffe.The innovation relates to a tube, whose outer jacket is made of metal and whose putter is made of a thermoplastic material, such as made of polyvinyl chloride or polyethylene. By combining such diverse building materials, it is possible to achieve the To give composite pipe properties that its field of application considerably expand. While the metal tube significantly increases the strength of the plastic, and the latter against mechanical Stress protects, experiences the former through the plastic pipe generally adequate protection against attacks by chemical agents.

Es hat sich jedoch gezeigt, daß die aus Kunststoff hergestellten Futterrohre nicht immer/völlig dicht halten, und es können unter ungünstigen Betriebsverhältnissen kleine Mengen an Feuchtigkeit bis zum Metallrohr vordringen. Außerdem besteht die Gefahr, daß das Kunststoffrohr geringe Mengen chemisch aggressiver Stoffe ausscheidet, wie z.B. Chlor, wenn zur Ausfütterung des Metallrohres als Kunststoff Polyvinylchlorid dient. Sofern ferner derartige Verbundrohre zum Fortleiten von Gasen insbesondere bei erhöhten Betriebstemperaturen Anwendung finden, können mitunter auch geringe Mengen der Gase durch den Kunststoff hindurchdiffundieren und an das Metallrohr gelangen und dieses angreifen, so daß es seine Aufgabe als Schutz- und Stützrohr nicht mehr erfüllen kann.It has been shown, however, that the casing pipes made of plastic do not always / completely hold tight, and it can under Under unfavorable operating conditions, small amounts of moisture can penetrate the metal pipe. There is also the risk that the plastic pipe separates small amounts of chemically aggressive substances, such as chlorine, if polyvinyl chloride is used to line the metal pipe as a plastic. If further such composite pipes to pass gases, especially at elevated operating temperatures, can sometimes also be used in small amounts the gases diffuse through the plastic and reach the metal tube and attack it, so that it does its job as Protective and support tube can no longer meet.

Um diese Nachteile zu vermeiden, ist daher auch s chon eine Rohrverbindung bekannt geworden, die aus einem Vulkanfiberrohr als Außenrohr und einem inneren Schutzrohr aus Kunststoff, insbesondere Vinylharzen, wie z.B. Mipolam, besteht. Es ist ferner nicht mehr neu, bei einem solchen Verbundrohr auch Drähte aus Metall oder ein Metalldrahtgewebe in das Außenrohr einzulegen. Eine solche Verstärkung reicht jedoch nicht aus, um den mechanischen Beanspruchungen der Rohre auf jeden Fall gerecht zu werden. Insbesondere vermag eine Drahteinlage die von außen auf das Kunststoffrohr einwirkenden Drücke oder Stöße nicht aufzufangen und das Kunststoffrohr nicht ausreichend zu schützen.In order to avoid these disadvantages, a pipe connection has therefore also become known which consists of a vulcanized fiber pipe as an outer tube and an inner protective tube made of plastic, in particular vinyl resins such as Mipolam. It is further it is no longer new to also insert wires made of metal or a metal wire mesh into the outer pipe in such a composite pipe. However, such a reinforcement is not sufficient to cope with the mechanical stresses on the pipes in any case. In particular, a wire insert is capable of attaching to the plastic pipe from the outside not to absorb the pressures or impacts and not to adequately protect the plastic pipe.

The type and manner of application of the protective layer takes place from case to case according to measures known per se. For example, thin oopanol tapes can be wound up. The cover can also be made of cheaper fabrics. For example, impregnated paper can be used. Sometimes, however, bitumen, wax, polyethylene or any type of varnish are sufficient to achieve the desired effect. Σε it is even possible to use even thin metal
