Description

Der Gegenstand der Erfindung ist ein neues Verfahren und eine Einrichtung zum Befestigen von Kesselröhren, insbesondere für Hochdruckkessel, um ein Undichtwerden und Herausziehen der Röhren zu vermeiden. Das neue \rerfahren besteht im wesentlichen darin, daß die Bohrlöcher für die zu befestigenden Röhren nicht vollständig durchgebohrt werden und der dadurch im BohrlochThe object of the invention is a new method and a device for fastening boiler tubes, in particular for high-pressure boilers, in order to prevent the tubes from leaking and being pulled out. The new \ r out essentially consists in that the holes are not completely bored through for the tubes to be fastened and characterized in the borehole

ίο stehenbleibende Ringansatz nach außen aufgebogen wird, worauf das Kesselrohr eingezogen und mit dem nach außen aufgebogenen Ringansatz verschweißt wird.ίο The ring attachment that remains standing is bent outwards is, whereupon the boiler tube is drawn in and welded to the outwardly bent ring attachment.

In der Zeichnung sind mehrere Ausführungsbeispiele der Erfindung dargestellt.Several exemplary embodiments of the invention are shown in the drawing.

In der Abb. 1 ist a die Rohrwand eines Hochdruckkessels, während b die Bohrlöcher für die zu befestigenden Siederöhren c (Abb. 3 und 4) sind. Diese Bohrlöcher werden, wie aus der Abb. 1 ersichtlich ist, nicht ganz durchgebohrt, so daß ein ringförmiger Rande? stehen bleibt. Dieser Rand d wird alsdann mit den üblichen Werkzeugen nach außen gebogen, wie die Abb. 2 zeigt. Nun wird das Siederohr c eingezogen und in üblicher Weise eingewalzt (Abb. 3), worauf der umgebördelte Rand d oder Flansch mit dem Rohrende verschweißt wird. Gleichzeitig kann das mit dem Rand d zu einem Ganzen verschweißte Rohrende noch nach außen kegelförmig erweitert werden (Abb. 4).In Fig. 1, a is the pipe wall of a high-pressure boiler, while b is the boreholes for the boiler pipes to be attached c (Fig. 3 and 4). As can be seen from Fig. 1, these boreholes are not drilled all the way through, so that an annular edge? stop. This edge d is then bent outwards with the usual tools, as Fig. 2 shows. Now the boiler pipe c is drawn in and rolled in in the usual way (Fig. 3), whereupon the beaded edge d or flange is welded to the pipe end. At the same time, the end of the pipe, which is welded to the edge d to form a whole, can be widened outwards in a conical shape (Fig. 4).

Um das Umbiegen des Flanschrandes d zu erleichtern, kann noch hinter dem Flanschrand d, wie in den Abb. 5 bis 8 dargestellt ist, eine Nut g eingedreht werden. Der Rand d kann hierbei, wie aus den Abb. 6 bis 8 links und rechts ersichtlich ist, verschieden nach außen umgebördelt werden und zwar, indem er entweder mit der Bohrlochwandung in einer Ebene liegt (Abb. 6 bis 8 links) oder außerhalb der Ebene der Bohrlochwandung liegt (Abb. 6 bis 8 rechts). Im letzteren Falle wird das mit dem Ansatz d zu verschweißende Rohrende nach außen erweitert, während es im ersteren Falle wieder kegelförmig nach außen umgebogen werden kann.To facilitate the bending of the flange edge d, d may still behind the flange, as shown in Figs. 5 to 8, a groove g are screwed. The edge d can here, as can be seen on the left and right in Figs. 6 to 8, be flanged outwards in different ways, namely by either lying in one plane with the borehole wall (Fig. 6 to 8 left) or outside the plane the borehole wall (Fig. 6 to 8 right). In the latter case, the pipe end to be welded to the shoulder d is widened outwards, while in the former case it can be bent outwards again in a conical shape.

Die Erfindung kann zur Befestigung von Kesselröhren jeder Art Anwendung finden, insbesondere können auch die bei Steilrohrkesseln in die zylindrischen Kessel einzuführenden Röhren in gleicher Weise befestigt werden.The invention can be used for fastening boiler tubes of any type, in particular, those to be introduced into the cylindrical boilers in the case of steep tube boilers Tubes are attached in the same way.
