Abstract

The heat resistant liner consists of a fabric impregnated with flame resistant CSM elastomer and with a thin metal layer applied to the inside or outside of the tube. Pref. the metal layer is formed by mixing Al powder into the CSM elastomer or by vapour depositing an Al coat onto the elastomer.

Description

Überzug schlauch Die Erfindung betrifft einen Überzugschlauch mit einer Einlage aus einem hitzebeständigen Werkstoff, beispielsweise Asbest. Cover hose The invention relates to a cover hose with an insert made of a heat-resistant material, for example asbestos.

Derartige Überzugsehläuche dienen dazu, Schlauchleitungen aller Art gegen Wärmeeinwirkung zu schützen.Such covering hoses are used for hose lines of all kinds to protect against the effects of heat.

Die bekannten Überzugsehläuche, bei denen beispielsweise die Einlage aus. hitzebeständigem Werkstoff als geklöppelter Asbestschlauch ausgebildet sein kann, halten nicht immer die vorgeschriebenen Temperaturen aus. Dieser Nachteil soll durch die Erfindung vermieden werden.The known covering hoses, in which, for example, the insert the end. heat-resistant material be designed as a braided asbestos hose cannot always withstand the prescribed temperatures. This disadvantage is to be avoided by the invention.

Die Erfindung besteht in erster Linie darin, daß die Einlage aus einem mit einem schwer entflammbaren CSM-Elastomer beschichteten Gewebe besteht und daß auf die Innen- und/oder Außenseite des Schlauches eine dünne Metallschicht aufgebracht ist. Dic Metallschicht kann entweder durch Beimischung von Aluminumpulver in das C;M-hlas-torner oder durch Aufdampfen von Aluminium auf das Ct-Elastomer gebildet sein.The invention consists primarily in the fact that the insert consists of a fabric coated with a flame retardant CSM elastomer and that a thin metal layer is applied to the inside and / or outside of the hose is. The metal layer can either be added by adding aluminum powder to the C; M-hlas-torner or by vapor deposition of Aluminum on the Ct elastomer be educated.

Durch die Metall schicht wird ein wesentlicher Teil der von außen einwirkenden Wärme abgestrahlt, so daß die Einlage aus hitzebeständigem Werkstoff wesentlich weniger unter dem Einfluß dieser Wärme steht.The metal layer makes a significant part of the exterior acting heat is radiated, so that the insert made of heat-resistant material is much less under the influence of this heat.

Zweckmäßigerweise ist der Innendurchmesser des Überzugschlauches etwa 1 bis 2 cm größer als der Außendurchmesser der medienführenden Schlauchleitung. Einerseits wird dadurch ein Überziehen des Überzugschlauches über die Armaturen der medienführenden Schlauchleitung ermöglicht; andererseits entsteht zwischen dem Uberzugschlauch und der Schlauchleitung ein Luftpolster, das eine isolierende Wirkung gegenüber einer Wärmebeanspruchung hervorruft. The inside diameter of the cover tube is expedient about 1 to 2 cm larger than the outer diameter of the hose line carrying the media. On the one hand, this means that the cover hose is pulled over the fittings the media-carrying hose line enables; on the other hand arises between the Cover hose and the hose line create an air cushion that has an insulating effect against thermal stress.
