Description

Es ist bekannt, Rohre gegen Wärmeverluste durch Umkleidung mit einer Isoliermasse zu schützen und diese Isoliermasse in Richtung des Rohrverlaufes durch mehrteilige Ringe zu unterteilen. Auch ist es bekannt, bei dieser Isolierung ein Drahtnetz zur Abdeckung zu verwenden, über welches ein Blechmantel als Schutzhülle gelegt wird.It is known to protect pipes against heat loss by cladding them with an insulating compound and in this insulating compound To divide the direction of the pipe run by multi-part rings. It is also known to use a wire mesh to cover this insulation, over which a Sheet metal jacket is placed as a protective cover.

Wenn als Isoliermasse solche von feiner ίο Körnung, z. B. pulverisierte Magnesia, verwendet wird, so genügt das Drahtnetz nicht, um die Masse bei der Einfüllung festzuhalten, und die Einfüllung muß deshalb bei geschlossener Ummantelung, d.h. also nach Umlegung des Blechmantels, geschehen. Das hat den Nachteil, daß sich bei der Einfüllung Hohlräume bilden können, die man nicht zu erkennen vermag. Solche Hohlräume können auch im Laufe des Gebrauchs entstehen, ohne daß man sie feststellen kann, weil nach Abnahme des Blechmantels die Isolierung ,ausfallen würde.If the insulating material is those of fine ίο grain, z. B. powdered magnesia is used the wire mesh is not sufficient to hold the mass during the filling, and the filling must therefore with the casing closed, i.e. after Wrapping of the sheet metal jacket, done. This has the disadvantage that when filling Can form cavities that cannot be seen. Such cavities can also arise in the course of use without being able to determine them because after removing the sheet metal jacket, the insulation would fail.

Die Erfindung macht es möglich, die Ein-The invention makes it possible to

füllungsarbeit zu "beobachten und Hohlräume zu vermeiden, und zwar dadurch, daß die Drahtnetzumhüllüng auf der Innenseite durch Paraffinpapier oder andere durchscheinende Mittel abgedeckt wird. Man ist alsdann in der Lage, die Verteilung des Isoliergutes genau zu beobachten.to "observe the filling work and to avoid cavities, namely by the fact that the Wire mesh wrapping on the inside through paraffin paper or other translucent Funds is covered. You will then be able to precisely distribute the insulating material to observe.

In der Zeichnung ist die Erfindung in vier Abbildungen wiedergegeben.In the drawing, the invention is shown in four figures.

Das Rohr a, das den üblichen Flansch b besitzt, ist dadurch isoliert, daß eine pulverförmige isolierende Füllmasse c aufgebracht ist. Damit diese Füllmasse Halt gewinnt, sind Ringet in Abständen auf das Rohr« aufgesetzt. Diese Ringe bestehen selbstverständlich auch aus einem Isoliergut, das zu einem festen Körper geformt ist, sie sind zwei- oder mehrteilig, und ihre Teile werden durch schwalbenschwanzförmige Keile e zu einem Ring zusammengehalten. Sodann wird über die Umfangsflächen der Ringe ein Drahtgewebe/ gelegt, dessen Maschen durch eine an der Innenseite anzubringende Lage von paraffiniertem Papier^ abgedeckt werden. Man könnte auch statt dieses Papiers einen Überzug von Wasserglas o. dgl. m. über das Drahtgewebe verwenden, das erstarrt, so daß die Maschen ausgefüllt sind. Außen wird dann das Ganze mit einem Mantel h aus verbleitem oder verzinktem Blech umgeben, damit es gegen äußere Einflüsse geschützt ist.The tube a, which has the usual flange b , is insulated in that a powdery insulating filler compound c is applied. So that this filling compound gains hold, rings are placed on the pipe at intervals. These rings naturally also consist of an insulating material which is formed into a solid body, they are in two or more parts, and their parts are held together to form a ring by dovetail wedges e. Then a wire mesh / is placed over the circumferential surfaces of the rings, the meshes of which are covered by a layer of paraffinized paper ^ to be attached to the inside. Instead of this paper, one could also use a coating of water glass or the like over the wire mesh, which solidifies so that the meshes are filled. On the outside, the whole thing is then surrounded by a jacket h made of leaded or galvanized sheet metal so that it is protected against external influences.
