 der Rohrlöcher anpressen, dass die äusseren Flächen der Rohrenden   fiir   die in der   Dampftechnik   bisher   angewendeten Drucke genügend dicht anliegen. Dadurch   entsteht zwischen Rohrwand und Rohr eine genügend feste Verbindung, um auch der infolge des Innendruckes entstehenden Zugkraft, die die Rohrenden aus der Rohrwand herausziehen will, widerstehen zu können. 



   Für hohe   Dampfdrücke   bedarf es höherer Sicherheiten gegen das Herausziehen der Rohrenden. 



  Eine solche wird bisher durch Eindrehen von Rillen a (Fig. 1) in die Rohrwand b erzielt, in die sich durch den Aufwalzprozess durch die   Diehtmasehine   Material des Rohres c einpresst. Dieses Verfahren hat jedoch den Nachteil, dass die angestrebte   möglichst grosse Dichtungsfläche zwischen   Rohr und Rohrwand verkleinert wird und dass das Material des Rohres einer starken Pressung ausgesetzt werden muss, damit das Rohrmaterial in die Rillen eindringt, wodurch die Wandstärke des Rohres geschwächt wird und die Gefahr des Abreissens des Rohres an der untersten Rille entsteht. Ausserdem lässt sich die Tiefe des Ein-

  Method for fastening pipe ends in pipe walls.

 of the pipe holes so that the outer surfaces of the pipe ends are tight enough for the pressures previously used in steam technology. This creates a sufficiently strong connection between the pipe wall and the pipe to be able to withstand the tensile force that is created as a result of the internal pressure and which tries to pull the pipe ends out of the pipe wall.



   For high steam pressures, greater security against pulling out the pipe ends is required.



  This has hitherto been achieved by screwing grooves a (FIG. 1) into the pipe wall b, into which the material of the pipe c is pressed by the rolling process by the diehtmasehine. However, this method has the disadvantage that the desired largest possible sealing surface between pipe and pipe wall is reduced and that the material of the pipe has to be subjected to strong pressure so that the pipe material penetrates the grooves, which weakens the wall thickness of the pipe and reduces the risk the tearing off of the pipe at the bottom groove occurs. In addition, the depth of the
