Description

Die Erfindung betrifft eine vorteilhafte einfachere Ausführung- der mit Schweißen kombinierten Walzverbindungen gemäß Patent 9o8 8r9 und besteht 'darin, daß - in Abwandlung der in den Abb.2 und 4 des Hauptpatents dargestellten Ausführungen - die Dichtschweiße 6 entfällt, so daß also das Kesselrohr ausschließlich in dem entsprechend verstärkten Zwischenring 3 mit oder ohne Bördel festgewalzt wird. .The invention relates to an advantageous, simpler embodiment with welding combined rolled connections according to patent 9o8 8r9 and consists of that - as a modification of the versions shown in Figures 2 and 4 of the main patent - The sealing weld 6 is omitted, so that the boiler tube exclusively in the correspondingly reinforced intermediate ring 3 is rolled down with or without a flange. .

Durch die in .dem Hauptpatent offenbarte Anordnung des Zwischenringes 3 ist schon erreicht, daß die .Anlage und die Dichtheit eines im Zwischenring eingewalzten Kesselrohres bei Erhöhung des Innendruckes infolge der Eigendehnung beider Teile zunehmen und bei entsprechender Gestaltung des Zwischenringes nicht mehr durch die Dehnung der Trommel- bzw. Behälterwand nachteilig beeinflußt werden. Damit ist aber auch die Hauptursache des Undichtwerdens von Hochdruck-Walzverbindungen nach der bisher üblichen Art behoben, so daß die im Hauptpatent noch angegebene zusätzliche Dichtschweiße 6 zwischen dem Rohrende und dem das Walzloch umfassenden Behälterteil, den im vorliegenden Fall der Zwischenring 3 bildet, folgerichtig wegfallen kann.By the arrangement of the intermediate ring disclosed in the main patent 3 has already been achieved that the system and the tightness of a rolled in the intermediate ring Boiler tube when the internal pressure increases as a result of the inherent expansion of both parts increase and no longer through the appropriate design of the intermediate ring Expansion of the drum or container wall can be adversely affected. But with that also the main cause of the leakage of high pressure rolled joints after the remedied previously usual type, so that the additional specified in the main patent Sealing weld 6 between the end of the pipe and the part of the container encompassing the roll hole, which in the present case forms the intermediate ring 3, can consequently be omitted.
