Description

  

      Rohrverbindung.       Die     Erfindung    betrifft     eine    Rohrverbin  dung, insbesondere für Druckleitungen, bei  welcher die Muffe auf die Rohrenden auf  geschrumpft ist, und besteht darin, dass die  Rohrenden mit     aufgestauchten    oder gewalz  ten Wulsten versehen     sind,    und dass die  Muffe mit diesen Wulsten durch     Schwei-          ssung    verbunden ist.  



  Ein Ausführungsbeispiel des Erfindungs  gegenstandes ist auf der     Zeichnung    schema  tisch dargestellt.  



  Die Rohre 1 und 2, die zum Beispiel  einer     Druckleitung    für     Hoehdruckdampf-          erzeuger    angehören, sind durch     Stauchung     oder     Walzung    an den Rohrenden gestaucht,  so dass     ein        ringförmiger    Wulst 3, 4 vorhan  den ist.  



  Die Rohre 1 und 2 sind kalt. Nachdem  das Rohr 1 bereit ist, wird eine Muffe 5 er  hitzt, über das Rohr 1 gelegt und das Rohr  2' gegen     das        Rohrende    1     hineingeschoben.       Nachdem die Muffe 5 abgekühlt ist, werden  die     -Endfugen    6 und 7 durch     Verschweissung     abgedichtet, so dass auch die Dichtheit der  Rohre gewährleistet ist und keine schäd  lichen Kerben entstehen, sobald die Muffe 5  mit den ringförmigen Wulsten 3 und 4 ver  schweisst     wird.     



  Die     Rohrverbindung    kann auch bei     lloch-          druckdampferzeugern    angewendet werden.



      Pipe connection. The invention relates to a pipe connection, in particular for pressure lines, in which the socket is shrunk onto the pipe ends, and consists in that the pipe ends are provided with swaged or rolled beads, and that the socket is connected to these beads by welding is.



  An embodiment of the subject invention is shown schematically in the drawing.



  The pipes 1 and 2, which belong, for example, to a pressure line for high pressure steam generators, are compressed by compression or rolling at the pipe ends, so that an annular bead 3, 4 is present.



  The pipes 1 and 2 are cold. After the pipe 1 is ready, a sleeve 5 is heated, placed over the pipe 1 and the pipe 2 'is pushed against the pipe end 1. After the sleeve 5 has cooled down, the -Endfugen 6 and 7 are sealed by welding, so that the tightness of the pipes is guaranteed and no harmful union notches arise as soon as the sleeve 5 is welded to the annular beads 3 and 4 ver.



  The pipe connection can also be used with 1-hole pressure steam generators.

Claims (1)

PATENTANSPRUCH: - Rohrverbindung, insbesondere für Druck leitungen, bei welcher die Muffe auf die Rohrenden aufgeschrumpft ist, dadurch ge kennzeichnet, dass die Rohrenden mit aufge- stauchten oder gewalzten Wulsten versehen sind, und dass die Muffe mit diesen Wulsten durch Schweissung verbunden ist. PATENT CLAIM: - Pipe connection, in particular for pressure lines, in which the socket is shrunk onto the pipe ends, characterized in that the pipe ends are provided with upset or rolled beads and that the socket is connected to these beads by welding.
