Description

Sicherung gegen das Undichtwerden eingewalzter Kesselrohre ' In Kessel- oder sonstige Behälterwandungen eingewalzte Rohre werden häufig durch Druck oder Wärmedehnungen in ihren Einwalzstellen auf Biegung beansprucht, wodurch die Befestigung der Rohre und die Dichtheit der Einwalzstellen leidet.Protection against leaking of rolled-in boiler tubes' In boiler or other container walls rolled tubes are often by pressure or Thermal expansions in their rolled-in points on bending stressed, whereby the fastening the pipes and the tightness of the rolled-in points suffers.

Nach der Erfindung wird die Esnwalzung selbst in bekannter Weise ausgeführt, es wird aber dafür gesorgt, daß vors der Einwalzung alle Biegungsbeanspruchungen ferngehalten werden, indem das Rohr in einer gewissen Entfernung von der eigentlichen Wälzstelle noch einmal ringförmig umfaßt und gehalten wird. Dies kann durch einen besonderen, mit dem Behälter fest verbundenen flanschähnlichen Körper geschehen, der einen das Rohr möglichst fest umfassenden Ringwulst trägt; man kann aber auch die Behälterwandung selbst durch Herauspressen und entsprechendes Bearbeiten außerhalb der Einwalzstelle mit einem solchen Ringwulst versehen. Werden besondere Flansche angewandt, so können diese als Einzel- oder Sammelflansche ausgebildet sein.According to the invention, the rolling itself is carried out in a known manner, but it is ensured that all bending stresses before rolling be kept away by placing the pipe at some distance from the actual Rolling point is once again encompassed and held in a ring shape. This can be done by a special flange-like body firmly connected to the container, which carries an annular bead encompassing the pipe as firmly as possible; but you can also the container wall itself by pressing out and corresponding processing outside the rolling point provided with such an annular bead. Will be special flanges applied, these can be designed as single or collective flanges.

In der Abbildung ist ein Beispiel einer solchen als Einzelflansch ausgebildeten Rohrsicherung im Längsschnitt des Rohres dargestellt.The illustration shows an example of such a single flange trained pipe fuse shown in the longitudinal section of the pipe.

Das Rohr a ist in üblicher Weise in die Behälterwandung b eingewalzt. über das Rohr a ist ein Flansch geschoben, der mittels nach innen vorspringender Ringwulste das Rohr außerhalb der Einwalzstelle umfaßt. Der Flansch c kann mit der Behälterwan-.fung b durch Nieten, Verschrauben, Schweißen o. dgl. verbunden sein, er kann auch gegebenenfalls aus der Behälterwandung hernusgepreßt oder sonstwie mit ihr in einem Stück hergestellt sein; wesentlich ist, daß das Rohr außerhalb seiner Einwalzstelle noch einmal allseitig gestützt ist. In der Abbildung sind zwei durch eine Ausnehmung getrennte Haltewulste d und e gezeigt, jedoch kommt es auf die Anzahl derselben nicht an; der äußere Haltewulst d allein würde zur Sicherung des Rohres genügen.The tube a is rolled into the container wall b in the usual way. A flange is pushed over the tube a, which flange surrounds the tube outside the rolling-in point by means of inwardly projecting annular beads. The flange c can be connected to the container wall. It is essential that the tube is supported again on all sides outside of its rolling-in point. In the figure, two retaining beads d and e are shown separated by a recess, but the number of these does not matter; the outer retaining bead d alone would be sufficient to secure the pipe.
