Description
Schweissverbindung an Rohren. Die Erfindung betrifft eine Schweissver- bindung an Rohren, insbesondere Drucklei- tungs.rohren. Die Erfindung besteht darin, dass mindestens eines der zusammengefügten Rohrenden verjüngt ist, meinen Raum des andern Rohrendes eingreift und dadurch die Rohre zentriert,
und dass die Schweissfuge ausserhalb des verjüngten Rohrendes angeord- net ist. Das Ende des verjüngten Rohres kann gegenüber,der Schweissfuge versetzt sein.
Ein Ausführungsbeispiel des Erfindungs- gegenstand-es ,ist auf der Zeichnung schema tsch -dargestellt.
Die Rohre 1 und 2 einer Druckleitung sind verformt. Während das Ende 3 ver jüngt ist, weist das. andere Rohrende einen Raum 4 auf, der durch Drehen, Walzen oder Stauchen hergestellt sein kann. Das Endei 3 des Rohres 1, passt in den Raum 4 des Roh res 2, wodurch die Rohre 1 und 2 zentriert werden. Die ;Schweissnaht 5 ist ausserhalb des verjüngten Rohrendes in der Fuge 6 an geordnet.
Das verjüngte Ende 3 des Rohres 1 kann gegenüber der Schweissnaht 5 in :der Strö- mungsriohtung 7 versetzt sein. Die Rohrenden 3 und 4 können durch spanabhebende Bearbeitung geformt sein.
Die Schweissverbindung kann beispiels weise an Rohren von Hoch;druckdampf- erzeu gern angewendet sein.
Welded connection on pipes. The invention relates to a welded connection on pipes, in particular pressure pipes. The invention consists in that at least one of the joined pipe ends is tapered, engages my space of the other pipe end and thereby centers the pipes,
and that the welding joint is arranged outside the tapered pipe end. The end of the tapered pipe can be offset from the welding joint.
An exemplary embodiment of the subject matter of the invention is shown in the schematic diagram.
The pipes 1 and 2 of a pressure line are deformed. While the end 3 is tapered, the other end of the pipe has a space 4 which can be made by turning, rolling or upsetting. The Endei 3 of the pipe 1 fits into the space 4 of the pipe res 2, whereby the pipes 1 and 2 are centered. The welding seam 5 is arranged outside the tapered pipe end in the joint 6.
The tapered end 3 of the tube 1 can be offset in relation to the weld seam 5 in the flow direction 7. The pipe ends 3 and 4 can be formed by machining.
The welded connection can be used, for example, on the pipes of high pressure steam generators.
