Description
Eine Verbindung zwischen Rohrwand und eingewalzten Rohren mit einer über jedes Rohrende geschobenen Kupferhülse, die sich mit ihrem inneren Ende von größerem Durchmesser gegen die Rohrwand legt und mit ihrem äußeren Ende zusammen mit dem äußeren, die Kupferhülse überdeckenden Rohrende umgebördelt ist, ist bekannt. Auch dünne Kupferhülsen mit einem sich gegen die Rohrwand legenden Absatz sowie aufgelötete Kupferhülsen sind nicht mehr neu.A connection between the pipe wall and rolled-in pipes with one over each Tube end pushed copper sleeve, which is with its inner end of larger diameter lays against the pipe wall and with its outer end together with the outer, the copper sleeve covering Pipe end is flanged is known. Also thin copper sleeves with one against the The heel that covers the pipe wall and the soldered-on copper sleeves are no longer new.
Der Erfindung gemäß wird ohne jede Bearbeitung des Rohres und der Kupferhülse lediglich durch das bekannte Einziehen der Rohrenden ein Absatz für die dünne, mit dem Rohr umgebördelte Kupferhülse geschaffen und die Kupferhülse in an sich bekannter Art rechtwinklig zu einem Flansch umgebogen, der mit dem Absatz des am Ende eingezogenen Rohres einen ■ winkelförmigen Raum bildet, wobei dann die an sich ebenfalls bekannte Anlötung durch Ausfüllen dieses winkelförmigen Raumes mit dem Lot erfolgt. Hierdurch wird, ohne daß zu diesem Zweck eine Nachbearbeitung des eingezogenen Rohrendes erforderlich wäre, durch' den rechtwinkligen Flansch der Kupferhülse eine scharfe rechtwinklige Anlagefläche zur Berührung mit der Innenseite der Rohrwand geschaffen, was zur guten Abdichtung an dieser Stelle wesentlich beiträgt. Begünstigt wird diese Abdichtung noch durch die Ausfüllung des winkelförmigen Raumes mit dem Lötmetall, das ein bis zu einem gewissen Grade nachgiebiges Widerlager darstellt.According to the invention, there is no machining of the pipe and the copper sleeve only by the known pulling in of the pipe ends a paragraph for the thin, with the Pipe flanged copper sleeve created and the copper sleeve in a known manner bent at right angles to form a flange, which is drawn in with the shoulder of the end Rohres an ■ angular space forms, in which case the per se as well known soldering is carried out by filling this angular space with the solder. As a result, the retracted pipe end does not need to be reworked for this purpose would be required by 'the right-angled flange of the copper sleeve a sharp right-angled contact surface created for contact with the inside of the pipe wall, which contributes significantly to a good seal at this point. This is favored Sealing by filling the angular space with solder, which represents an abutment that is yielding to a certain extent.
In der Zeichnung ist eine beispielsweise Ausführungsform an zwei übereinanderliegenden Rohren \-eranschaulicht, wobei am oberen Rohr ein unfertiger und am unteren Rohr der fertige Zustand angenommen ist.The drawing shows an example of an embodiment of two superimposed Pipes \ - illustrated, with an unfinished pipe at the top and an unfinished pipe at the bottom Tube the finished state is assumed.
α ist das an seinem Ende eingezogene Rohr und b die über das eingezogene Ende geschobene dünne Kupferhülse, deren inneres Ende rechtwinklig zu einem Flansch h umgebogen ist. Zwischen diesem Flansch h und +5 dem durch das Einziehen des Rohrendes entstandenen Absatz befindet sich ein winkelförmiger Raum, der durch das Lot c ausgefüllt ist. e ist die Rohrwand, an deren äußerer Seite das Ende des eingezogenen Rohres α und das äußere Ende der Kupferhülse b zunächst in zylindrischer Form überstehen (oberes Rohr), worauf dann das überstehende Ende des Rohres α nach außen so umgebogen wird, daß die Bördelung d entsteht, die das mit umgebördelte überstehende Ende der Kupferhülse b überdeckt. α is the tube drawn in at its end and b is the thin copper sleeve pushed over the drawn-in end, the inner end of which is bent at right angles to form a flange h. Between this flange h and +5 the shoulder created by pulling in the pipe end there is an angular space that is filled by the perpendicular c. e is the tube wall, on the outer side of which the end of the drawn-in tube α and the outer end of the copper sleeve b protrude initially in a cylindrical shape (upper tube), whereupon the protruding end of the tube α is bent outwards so that the flange d arises, which covers the beaded protruding end of the copper sleeve b .
