Description
Nachbehandlung von seitlichen, angeschweißten Rohranschlüssen bei Mehrlagenhohlkörpern Im Patent $66655 ist ein Verfahren zur Nachbehandlung von seitlichen, angeschweißten Rohranschlüssen bei Mehrlagenhohlkörpern, insbesondere Wickelkörpern, beschrieben, wobei eine Glühbehandlung der Schweißstellen, die im Bereich des seitlichen Anschlußrohres liegen, mittels elektrischer Induktionserwärmung erfolgt. Es wurde damit die Aufgabe gelöst, ein zur Wandung etwa senkrecht stehendes Rohr, das z. B. zur Zu- und Abführung von Reaktionsteilnehmern dient, durch die einzelnen Wickellagen durchzuführen und mit dem Kernrohr und gegebenenfalls den Lagen so zu verbinden, daß die Verbindung den auftretenden Beanspruchungen gewachsen ist und dabei völlige Dichtheit gegenüber dem Innendruck gewährleistet.Post-treatment of welded-on pipe connections on the side Multi-layer hollow bodies The patent $ 66655 describes a process for the post-treatment of lateral, welded pipe connections for multi-layer hollow bodies, in particular wound bodies, described, with an annealing treatment of the welds in the area of the lateral Connection pipe lie, takes place by means of electrical induction heating. It was thus the problem solved, a to the wall approximately perpendicular tube, the z. B. is used to feed and discharge reaction participants through the individual winding layers to be carried out and to be connected to the core tube and, if necessary, the layers, that the connection can cope with the stresses that arise and is complete Guaranteed tightness against the internal pressure.
Es wurde nun gefunden, daß dieses Ziel auch dann erreicht wird, wenn man an Stelle der elektrischen Induktionserwärmung eine Glühbehandlung der Schweißstellen mittels Gasflamme vornimmt, wobei entweder jede Schweißlage für sich, gegebenenfalls bereits schon während des Schweißvorganges, oder mehrere Lagen gemeinsam behandelt werden können. Es wird demnach gerade mit einer Methode gearbeitet, welche dem üblichen Vorgehen bei der Glühung dickwandiger Gefäße entgegengesetzt ist. Während sonst eine möglichst gleichmäßige Temperaturverteilung über den ganzen Körper angestrebt werden muß, soll nach dem vorliegenden Vorschlag nur in dem die Schweißung des seitlichen Anschlußrohres enthaltenden Teil ein möglichst intensiver Wärmestau erzielt werden und die Erwärmung eines größeren Bereiches der einzelnen Lagen vermieden werden, damit zusätzliche neue Eigenspannungen und ein Verziehen des Körpers nur in möglichst geringem Umfang auftreten können.It has now been found that this goal is achieved even if instead of electrical induction heating, the welding points are annealed by means of a gas flame, with either each welding layer for itself, if necessary already during the welding process, or several layers treated together will can. It is therefore currently working with a method that is the usual The procedure for annealing thick-walled vessels is the opposite. While otherwise The aim is to achieve as even a temperature distribution as possible over the whole body must be, according to the present proposal, only in which the welding of the side Connection pipe containing part as intense as possible heat build-up can be achieved and the heating of a larger area of the individual layers can be avoided, thus additional new internal stresses and a distortion of the body only in as much as possible can occur on a small scale.
