Die Erfindung betrifft die Verbindung einesThe invention relates to the connection of a Überhitzerrohres mit einem Sammler unter Zwischenschaltung eines Anschweißstutzens und besteht darin, daß das Rohr in den Stutzen eingewalzt und mit ihm an einer Stelle durch Schweißung verbunden ist, welche weit genug von der Walzstelle entfernt ist, damit die durch die Schweißung bewirkte Wärmedehnung sich auf die Walzstelle nicht mehr störend auswirkt.Superheater tube with a collector with the interposition of a welded socket and consists in the fact that the pipe is rolled into the socket and with it at one Point is connected by welding, which is far enough away from the rolling point, so that the thermal expansion caused by the weld does not affect the rolling point more disruptive. Es ist bekannt, in Sammlern Stutzen einzuschrauben und zu verschweißen, an welche Stutzen das Rohr angeschweißt wird. Bei Walzverbindungen mit Dichtschweißung ist bisher die Schweißstelle unmittelbar am Sammler angeordnet worden, wodurch die Haftkraft beeinträchtigt wird. Erfindungsgemäß wird daher das Rohr nicht unmittelbar in den Sammler, sondern unter Zwischenschaltung eines Stutzens eingewalzt, mit dem es außerhalb der Walzstelle durch Schweißung verbunden ist. Gleichzeitig werden die Spannungen an der Austrittsstelle des Rohres aus dem Sammler durch den hervortretenden Stutzen verringert.It is known that nozzles can be screwed into collectors and welded to them Nozzle the pipe is welded on. In the case of rolled joints with sealing welding so far, the welding point has been arranged directly on the collector, whereby the adhesive force is impaired. According to the invention the pipe is therefore not directly in the collector, but with the interposition rolled into a nozzle with which it is connected by welding outside the rolling point. At the same time, the Stresses at the exit point of the pipe from the collector by the protruding Neck reduced. Die Erfindung ist in der Zeichnung im Schnitt dargestellt. In den Sammler 1 ist der Stutzen 2, in welchen das Rohr 3 eingewalzt ist, mit Bund eingesetzt und dicht geschweißt. Der Stutzen 2 ragt etwa 50 mm über den Sammler hervor und ist an seinem Ende mit dem Rohr 3 verschweißt. Auf die beschriebene Weise ist es möglich, eine Walzverbindung mit Dichtschweißung herzustellen, ohne daß dadurch die Haftfestigkeit der Walzverbindung ungünstig beeinflußt würde. Um das Rohr in üblicher Weise bördeln zu können, ist der Stutzen an seinem inneren Ende kegelig ausgebildet.The invention is shown in section in the drawing. In collector 1 is the Nozzle 2, into which the tube 3 is rolled, inserted with a collar and welded tightly. The connector 2 protrudes about 50 mm over the collector and is at its end welded to the tube 3. In the manner described it is possible to produce a roller joint to be produced with sealing welding without impairing the adhesive strength of the roller joint would be adversely affected. In order to be able to flare the pipe in the usual way, the connecting piece is on its inner side Conical end. Paxentanspruch :Pax entitlement: Überhitzerrohrverbindung mit einem Sammler unter Zwischenschaltung eines mit diesem und dem Rohr verschweißten Stutzens, dadurch gekennzeichnet, daß das Rohr (3) dort in den Stutzen (2) ein-, gewalzt ist, wo er außen gegen die Sammlerwandung (ι) anliegt, und mit ihm an einer Stelle verschweißt ist, welche etwa 50 mm oder mehr von der Walzstelle entfernt ist.Superheater pipe connection with a collector with the interposition of a with this and the pipe welded connector, characterized in that the pipe (3) there in the connector (2), is rolled, where it rests against the outside of the collector wall (ι), and with it a point is welded which is about 50 mm or more away from the rolling point is.
