 Kesselrohr dicht abdeckt. Auf diese Weise werden die Rohre an der gefährdeten Stelle verstärkt und gegen die durch das Einwalzen drohende   Verschwächung   geschützt. Ebenso wird ein Verbrennen der Rohrränder durch die heissen Gase und das damit Hand in Hand gehende Undichtwerden bzw. Rinnen verhindert. 



   Die Zeichnung veranschaulicht den Erfindungsgegenstand   beispielsweise, Imd zwar   zeigt Fig. 1 den Rohrboden a eines   Kessels   in Stirnansicht mit den Kessclrohren b und Fig. 2 in etwas grösserem   1Iassstabe den   Längsschnitt durch das Ende eines in den Rohrboden a eingewalzten Kesselrohres b mit dem hülsenfömigen   Rohreinsatz c, dessen umgebördelter Aussenrand d   an den Rohrboden angepresst ist und die Stelle zwischen Rohr b und Boden a dicht abdeckt. 
 EMI1.3 
 die Undichtheit durch Nachwalzen der Rohre entstanden ist, wieder dicht gemacht werden.

 EMI1.2
 Covering the boiler tube tightly. In this way, the pipes are reinforced at the endangered point and protected against the weakening threatened by the rolling. Burning of the pipe edges due to the hot gases and the leaks and gutters that go hand in hand with them is also prevented.



   The drawing illustrates the subject of the invention, for example, while Fig. 1 shows the tube sheet a of a boiler in an end view with the boiler tubes b and Fig. 2 shows, in a somewhat larger scale, the longitudinal section through the end of a boiler tube b rolled into the tube sheet a with the sleeve-shaped tube insert c whose beaded outer edge d is pressed against the tube sheet and tightly covers the point between tube b and base a.
 EMI1.3
 the leakage caused by rolling the pipes must be made tight again.

Claims

PATRENT CLAIM: Device for protecting and sealing boiler tubes rolled into the tube sheet, characterized in that a sleeve-shaped insert is rolled into the boiler tube, which with its flanged outer edge tightly covers the point between tube sheet and boiler tube and reinforces the rolled-in boiler tube end.
