Description

  

      Heizleitung,    insbesondere für     Fernheizanlagen.       Die Erfindung betrifft eine aus einem  Bündel von zwei oder mehreren Rohrsträngen  bestehende,     wärmeisolierte    Heizleitung, ins  besondere für     Fernheizanlagen,        und    besteht  darin, dass das Bündel von einem gemein  samen     Isoliermantel    umschlossen ist, zum  Zweck, von einer Einzelisolierung der Lei  tungen absehen zu können.  



  Auf der Zeichnung     sind    einige Ausfüh  rungsbeispiele :des Erfindungsgegenstandes  dargestellt.  



       F'ig.    1, 2     bezw.   <B>3</B> ist je ein Querschnitt  durch eine erste, zweite     bezw.        :dritte        Ausfüh-          rungsf        orm.     



  a ist eine in einen unterirdischen Kanal b  eingebaute     Vorlaufleitung    und c     bezw.    d.       bezw.    e sind mit der     Vorlaufleitung    zu  einem Rohrbündel vereinigte     Rücklauflei-          tungen    einer     Fernheizanlage.    Um eine Ein  zelisolierung der     Rücklaufleitungen        bezw.     ein Ausstopfen     :der    freien Räume mit Iso  liermaterial überflüssig zu machen, ist das  Rohrbündel in einen um     dessen    Umfang her-    umgelegten Mantel f von     Isoliermitteln    ein  gehüllt.

   Dadurch     wird,das    ganze Rohrsystem  in der Weise vor     Wärmeverlusten    geschützt,  dass es für eine einwandfreie Übertragung  der     Wärme    an ihren     Bestimmungsort    genügt,  die Vorlaufleitung für sich zu     isolieren.    Nach  beendigter Verlegung :der Rohre     wird    der  Isoliermantel durch Einhüllen des Bündels  in     deckenförmige        Isoliermittel    hergestellt.  Dadurch wird der für die Isolierung erfor  derliche Zeitaufwand :erheblich abgekürzt.



      Heating cable, in particular for district heating systems. The invention relates to a bundle of two or more pipe strings, thermally insulated heating cable, in particular for district heating systems, and consists in the fact that the bundle is enclosed by a common insulating jacket, for the purpose of being able to refrain from individual insulation of the lines.



  On the drawing are some Ausfüh approximately examples: the subject of the invention is shown.



       F'ig. 1, 2 and <B> 3 </B> is a cross section each through a first, second and respectively. : third embodiment.



  a is a flow line built into an underground channel b and c respectively. d. respectively e are return lines of a district heating system that are combined with the flow line to form a tube bundle. To a single isolation of the return lines respectively. A stuffing: To make the free spaces with insulating material superfluous, the tube bundle is wrapped in a jacket f of insulating material wrapped around its circumference.

   As a result, the entire pipe system is protected from heat loss in such a way that it is sufficient to insulate the flow line for proper transfer of the heat to its destination. After the installation of the pipes is complete, the insulating jacket is produced by wrapping the bundle in blanket-shaped insulating material. This significantly shortens the time required for isolation:
