Description

Wärmeisolierte Rohrleitung, bei der zur Hauptleitung im Winkel verlaufende Rohrleitungen angeordnet sind Die Erfindung geht aus von einer wärmeisolierten Rohrleitung, bestehend aus zwei oder mehreren miteinander zu verbindenden Metall- insbesondere Stahlrohren, die jeweils von einer Kunststoffisolierschicht und einem Schutzrohr ummantelt sind, wobei zur Hauptleitung in einem Winkel verlaufende Rohrleitungen vorgesehen sind.Heat-insulated pipeline with the one that runs at an angle to the main line Pipelines are arranged The invention is based on a heat-insulated pipeline, consisting of two or more metal to be connected to one another in particular Steel pipes, each made of a plastic insulating layer and a protective pipe are sheathed, with pipes running at an angle to the main line are provided.

Die Aufgabe der Erfindung besteht demgegenüber darin, Rohrleitungen der soeben genannten Art insoweit zu verbessern, daß vor allem beim Eingraben der Rohrleitung in das Erdreich durch Wärmespannungen keine Risse an der Verbindungsstelle zwischen Hauptleitung und abgewinkelten Rohrleitungen entstehen.In contrast, the object of the invention is to provide pipelines of the type just mentioned to the extent that, above all, when digging in the Pipeline into the ground due to thermal stresses no cracks at the connection point between the main line and angled pipes.

Zur Lösung dieser Aufgabe ist bei der Erfindung vorgesehen, daß die im Winkel zu der Hauptleitung unmittelbar verbundenen Schutzrohre eine Isolierschicht mit ovalem, parallel zur Hauptleitung angeordneten Innenquerschnitt aufweisen, der allmählich unter Beibehaltung der Querschnittsbreite mit zunehmender Entfernung von der Hauptleitung in einen Querschnitt übergeht, der dem des einzubettenden Metallrohres entspricht.To solve this problem, the invention provides that the an insulating layer at an angle to the main line directly connected protective pipes having an oval inner cross-section arranged parallel to the main line, the gradually while maintaining the cross-sectional width with increasing distance from the main line merges into a cross-section that corresponds to that of the metal pipe to be embedded is equivalent to.

Durch di# Erfindung wird so erreicht, daß vor allem beim Eingraben der Rohrleitung in das Erdreich an den Abzweigstellen durch die Wärmeentwicklung keine Dehnungsrisse entstehen. Durch den an der Abzweigstelle besonders geformten lichten Querschnitt der Nebenleitungen ist es möglich, die Rohrleitung fest und in axialer Richtung unverrückbar in das Erdreich einzugraben. Bei Längenänderungen der Hauptleitung können die daran angeschlossenen Abzweigleitungen ohne weiteres im elastischen Bereich derselben in Axialrichtung der Hauptleitung in der sie umgebenden Kunststoffleitung bewegt werden.Through the invention it is achieved that especially when digging in the pipeline into the ground at the branch points due to the development of heat no expansion cracks occur. Due to the specially shaped at the junction clear cross-section of the secondary lines, it is possible to fix the pipeline and to dig immovably in the axial direction into the ground. With changes in length the branch lines connected to it can easily be connected to the main line in the elastic area of the same in the axial direction of the main line in the surrounding line Plastic pipe can be moved.

Die Erfindung wird an Hand eines Ausführungsbeispiels in der Zeichnung näher erläutert. Die Zeichnung ist ein Schnitt durch die Rohrleitungen.The invention is illustrated using an exemplary embodiment in the drawing explained in more detail. The drawing is a section through the pipelines.

Aus der Zeichnung ist die wärmeisolierte Rohrleitung, bestehend aus zwei oder mehreren miteinander zu verbindenden Metall- insbesondere Stahlrohren 1, 2, die jeweils von einer Kunstschaumstoffisolierschicht 3, 4 und einem Schutzrohr 5, 6 ummantelt sind, wobei zur Hauptleitung 1 im Winkel verlaufende Rohrleitungen 2 vorgesehen sind, zu erkennen.The drawing shows the heat-insulated pipeline, consisting of two or more metal, in particular steel pipes 1, 2 to be connected to one another, each of which is encased by a synthetic foam insulating layer 3, 4 and a protective pipe 5, 6 , with pipelines 2 running at an angle to the main line 1 are intended to be recognized.

Die im Winkel zu der Hauptleitung 1 unmittelbar verbundenen Schutzrohre 6 weisen eine Isolierschicht 4 mit ovalen parallel zur Hauptleitung 1 angeordneten Innenquerschnitt auf, der allmählich unter Beibehaltung der Querschnittsbreite B mit zunehmender Entfernung von der Hauptleitung 1 in einen Querschnitt übergeht, der dem des einzubettenden Metallrohres 2 entspricht.The protective tubes 6, which are directly connected at an angle to the main line 1, have an insulating layer 4 with an oval inner cross-section arranged parallel to the main line 1 , which gradually changes to a cross-section similar to that of the metal pipe 2 to be embedded, while maintaining the cross-sectional width B, with increasing distance from the main line 1 is equivalent to.

Der Übergang erfolgt stufenförmig. Die im Winkel zu der Hauptleitung 1 unmittelbar verbundenen Schutzrohre 6 sind zwei oder mehrere überlappte, zusammengeschweißte Einzelrohre.The transition takes place in steps. The protective tubes 6, which are directly connected at an angle to the main line 1, are two or more overlapped individual tubes welded together.
