  Verfahren zur Isolierung von kalte oder warme Substanzen leitenden Rohren, und nach dem Verfahren hergestellte Rohrisolierung
Es ist bekannt, kalte oder warme Substanzen führende Rohre zwecks Isolierung mit einer Lage synthetischen Schaumstoffes zu umgeben und über den Schaumstoff einen aus einer Kunststoffolie, z. B. einer Polyvinylchloridfolie, bestehenden Mantel zu legen und die Längsnaht der Folie in geeigneter Weise zu verschliessen.



   Der Gegenstand der Erfindung ist nun ein Verfahren zur Isolierung von kalte oder warme Substanzen leitenden Rohren mittels synthetischen Schaumstoffes, das sich dadurch auszeichnet, dass der das Rohr zylindrisch umgebende Schaumstoff mit einem vorfabrizierten Mantelrohr aus Kunststoff versehen wird, das axial aufgeschnitten ist, so dass es an der Trennfuge gespreizt und über den Schaumstoff   ge    legt werden kann, worauf die Spreizung wieder aufgehoben und die Trennfuge verschlossen wird.



   Vorteilhaft wird man für das den Schaumstoff umgebende Mantelrohr ein Rohr aus Polyvinylchlorid verwenden.



   Die Erfindung bezieht sich ausserdem auf die nach dem Verfahren hergestellte Rohrisolierung, die sich dadurch auszeichnet, dass über den das Rohr zylindrisch umgebenden Schaumstoff ein eine längsverlaufende Trennfuge aufweisendes Mantelrohr aus Kunststoff gelegt ist, und dass ein Verschliessmittel zum Verschliessen der Trennfuge vorgesehen ist.



   In der Zeichnung ist ein Ausführungsbeispiel eines nach dem Verfahren gemäss der Erfindung isolierten Rohres dargestellt, und zwar zeigt:
Fig. 1 ein isoliertes Rohrstück, wobei die linke Hälfte der Figur im Schnitt erscheint,
Fig. 2 den Seitenriss zu Fig. 1 und
Fig. 3 ein rechtwinklig abgebogenes isoliertes Rohrstück, in   kleinerem    Massstab.



   Mit 1 ist ein kalte oder warme Substanzen leitendes Rohr bezeichnet; es ist von einer Lage synthetischem Schaumstoff 2 umgeben. Der Schaumstoff ist von der Rolle, wie er in den Handel kommt, herausgeschnitten und um das Rohr 1 herumgelegt. Die Enden des Schaumstoffes stossen schräg zur Radialen zusammen und können z. B. durch Klebung oder mittels eines zwischengelegten, beidseitig klebenden Bandes zusammengefügt sein.



   Auf dem das Rohr 1 zylindrisch umgebenden Schaumstoff ist ein   vosfabriziertes    Mantelrohr 3 aus Kunststoff, vorzüglich ein nach dem Strangpressverfahren hergestelltes Polyvinylchloridrohr, gelegt, das bei A axial aufgeschnitten ist, so dass es eine Trennfuge bildet, an welcher es gespreizt und über den Schaumstoff 2 gelegt werden kann. Nach dem Auflegen des Mantelrohres 3 auf den Schaumstoff schliesst sich die Spreizung wieder und die Trennfuge bei A wird hierauf z. B. mittels eines Klebbandes 4, das auch aus PVC-Kunststoff hergestellt sein kann, verschlossen. Andere Verschliessarten und -mittel zum Verschliessen der Trennfuge sind ohne weiteres denkbar. So könnte die Trennfuge des Mantelrohres auch durch Hochfrequenzschweissung oder durch Heissluftschweissung verschlossen werden.

   Ein anderes Mittel würde in der Verwendung von Heftklammern bestehen, die quer zur Trennfuge A einge  schlossen    werden und deren Stege mit einem Klebband abgedeckt werden könnten.



   Da die Verwendung von vorfabrizierten Mantelrohren besonders für geradachsige Rohrstücke in Betracht fällt, wird man Rohrkrümmer vorteilhaft mit einer Bandagierung aus Kunststoffband isolieren, wie das in der Fig. 3 an dem Rohrkrümmer 5 dargestellt ist.   



  
 



  Process for the insulation of pipes that conduct cold or warm substances, and pipe insulation produced according to the process
It is known to surround pipes leading to cold or warm substances for the purpose of insulation with a layer of synthetic foam and over the foam one made of a plastic film, e.g. B. a polyvinyl chloride film to put existing coat and to close the longitudinal seam of the film in a suitable manner.



   The object of the invention is now a method for the insulation of pipes that conduct cold or hot substances by means of synthetic foam, which is characterized in that the foam surrounding the pipe is provided with a prefabricated plastic jacket pipe which is cut open axially so that it can be spread at the parting line and placed over the foam, whereupon the spreading is canceled again and the parting line is closed.



   A tube made of polyvinyl chloride will advantageously be used for the jacket tube surrounding the foam.



   The invention also relates to the pipe insulation produced by the method, which is characterized in that a casing pipe made of plastic with a longitudinal parting line is placed over the foam surrounding the pipe in a cylindrical manner, and that a closure means is provided for closing the parting line.



   The drawing shows an exemplary embodiment of a pipe insulated using the method according to the invention, namely:
Fig. 1 shows an isolated pipe section, the left half of the figure appears in section,
Fig. 2 shows the side elevation of Fig. 1 and
3 shows an insulated pipe section bent at right angles, on a smaller scale.



   1 with a cold or warm substance conductive pipe is referred to; it is surrounded by a layer of synthetic foam 2. The foam is cut out of the roll as it comes on the market and placed around the tube 1. The ends of the foam collide obliquely to the radial and can, for. B. be joined together by gluing or by means of an interposed, double-sided adhesive tape.



   A pre-fabricated casing pipe 3 made of plastic, preferably a polyvinyl chloride pipe produced by the extrusion process, is placed on the foam cylindrical around the pipe 1, which is cut open axially at A so that it forms a parting line at which it is spread and placed over the foam 2 can be. After placing the jacket pipe 3 on the foam, the expansion closes again and the parting line at A is then z. B. closed by means of an adhesive tape 4, which can also be made of PVC plastic. Other types and means of closing for closing the parting line are readily conceivable. The parting line of the jacket pipe could also be closed by high-frequency welding or by hot air welding.

   Another means would consist in the use of staples, which are enclosed transversely to the parting line A and whose webs could be covered with an adhesive tape.



   Since the use of prefabricated casing pipes is particularly suitable for straight-axis pipe sections, pipe bends will advantageously be insulated with a bandage made of plastic tape, as shown in FIG.
