Description

Die Erfindung betrifft eine w :fitere Ausbildung einer Schweißverbindung gemäß Patent 854005, bei der an jedes Rohrende, ein Anschlußrohrstück aus Werkstoff mit demselben Ausdehnungskoeffizienten, vorzugsweise aus dem gleichen Werkstoff, angeschweißt ist und daß beide Anschlußrohrstücke auf einem Teil ihrer Länge sich überdecken und durch eine großflächige Schweiß- odeir Lötverbindung zu einem einheitlichen Zwischenstück vereinigt sind.The invention relates to a better design of a welded connection according to patent 854005, in which a connecting pipe piece made of material with the same expansion coefficient, preferably made of the same material, is welded to each pipe end and that both connecting pipe pieces overlap over part of their length and are connected by a Large-area welding or soldering connections are combined to form a uniform intermediate piece.

Die große Sicherheit dieser Verbindung beruht insbesondere auf der bevorzugten axialen Lage und der Größe der verschweißten Flächen.The great security of this connection is based in particular on the preferred axial position and the size of the welded surfaces.

Während bei sehr vielen Stählen oder Metallen eine Schweißeng oder Löteng möglich ist, die sehr großen mechanischen Beanspruchungen gewachsen ist, kann es auch Fälle geben, bei denen aus besonderen Gründen, z. B. bei begrenzter Schweiß- oder Lötbarkeit der Werkstoffe, eine zusätzliche Sicherung der großflächigen Schweißverbindung notivendig oder erwünscht ist.While with a lot of steels or metals a welding or Soldering is possible that can withstand very high mechanical loads, there may also be cases where for special reasons, e.g. B. at limited The materials can be welded or soldered, an additional safeguard for the large-area Welding connection is necessary or desired.

Erfindungsgemäß kann eine derartige Sicherung durch Anwendung an sich bekannter Mittel zur Entlastung der Schweiß- oder Lötverbindung gegenüber mechanischen Beanspruchungen erreicht werden. Es kann z. B. eine Verzahnung der sich überdeckenden Rohrteile oder eine Stiftsicherung %-orgesehen sein. Verschiedene Ausführungsformen des Erfindungsgedankens sind in der Zeichnung in vier Abbildungen dargestellt. In dieser Zeichnung sind lediglich die miteinander verschweißten oder verlöteten Zwischenstücke e und d der im Hauptpatent dargestellten Gesamtverbindung wiedergegeben. An jedes dieser Teile c und d schließt sich ein Rohrende des laufenden Rohrstranges an.According to the invention, such a fuse can be applied per se known means for relieving the welded or soldered connection with respect to mechanical ones Stresses can be achieved. It can e.g. B. a toothing of the overlapping Pipe parts or a pin lock must be provided. Different embodiments of the inventive concept are shown in the drawing in four figures. In This drawing shows only the intermediate pieces that are welded or soldered to one another e and d of the overall compound shown in the main patent. To each these parts c and d are followed by a pipe end of the running pipe string.

In Abb. Z ist eine Verzahnung e gezeigt; in Abb. 2 sind zusätzliche Rundschweißnähte f dargestellt; Abb. 3 läßt punkt- oder strichförmige Schweißengen g bzw. h durch das äußere Rohr hindurch erkennen, während bei der Ausführungsform nach Abb: ,4 die Verankerung durch eine Wellung i herbeigeführt wird.In Fig. Z a toothing e is shown; in Fig. 2 are additional Round welds f shown; Fig. 3 shows point or line weld seams Detect g and h through the outer tube while in the embodiment according to Fig:, 4 the anchoring is brought about by a corrugation i.
