Description

Es ist bei Rohrverbindungen, bei denen die Stirnseiten der Rohrenden stumpf miteinander verschweißt sind, bekannt, über die Schweißnaht eine Hülse oder ein Muffenrohr zu schieben, das seinerseits mit den Rohrenden verschweißt werden kann und zur Aufnahme der Biegungsbeanspruchungen dient. Bei bisher bekanntgewordenen Ausführungen dieser Art wurde zuerst die Stumpf sch w.eißung vorgenommen und nach Fertigstellung der Schweißnaht die Hülse über die Schweißstelle geschoben. Ein derartiges Verfahren schließt das Anbringen einer verstärkten Schweißnaht, d. h. einer Schweißnaht, deren Breite dieWandstärkeder Rohre übertriff t, ohne nachträgliches Verformen des übergeschobenen Muffenrohres aus. Legt man trotzdem auf eine verstärkte Schweißnaht Wert, so muß man die übergeschobene Hülse in zwei Teile ao zerlegen und jeden Teil gesondert mit den Rohrenden verschweißen. Abgesehen von einer umständlichen Herstellung ist diese Atisführung im Falle eines teilweisen Aufplatzens der Befestigungsschweißnähte unsicher. It is with pipe connections in which the end faces of the pipe ends are butted together are welded, known to push a sleeve or a socket pipe over the weld, which in turn with the pipe ends can be welded and is used to absorb the bending stresses. With previously known versions In this way, the butt welding was carried out first and after completion of the weld seam, the sleeve is pushed over the weld. One such procedure includes making a reinforced weld, d. H. a weld whose Width exceeds the wall thickness of the pipes without subsequent deformation of the Socket pipe. If you still value a reinforced weld seam, then you must you disassemble the sleeve pushed over into two parts ao and each part separately with the Weld the pipe ends. Apart from a laborious production, this guide is in the event of a partial burst the fastening welds are unsafe.

Der Erfindung liegt die Aufgabe zugrunde, eine Rohrverbindung anzugeben, bei der eine verstärkte Schweißnaht angebracht und gleichzeitig eine ungeteilte Hülse verwendet werden kann. Die Lösung besteht darin, daß das Muffenrohr mit einer oder mehreren über der Schweißnaht liegenden, als Ringsektor ausgebildeten Durchbrechungen versehen ist, durch die hindurch unter Drehung des Muffenrohres die Herstellung1 der Schweißnaht erfolgt ist. Die Herstellung der Schweißnaht geschieht so, daß man zuerst das Muffen-■' rohr über beide Rohre schiebt und dadurch eine gute Zentrierung erzielt. Nachdem durch die Schlitze hindurch die eigentliche Schweißung vorgenommen ist, kann man außerdem noch die Schlitze der Muffe zur Erhöhung der Festigkeit^ der Schweißverbindung mit den Rohrenden verschweißen. Derjenige Umfang des Muffenrohres, auf dem die Schlitze liegen, wird durch vorheriges Walzen erweitert, so daß er eine verstärkte Rundnaht aufnehmen kann.The invention is based on the object of specifying a pipe connection in which a reinforced weld seam can be applied and at the same time an undivided sleeve can be used. The solution is that the sleeve tube is provided with one or more overlying the weld seam formed as a ring sector openings, the weld is carried out by passing under rotation of the sleeve tube manufacturing. 1 The weld seam is produced by first pushing the socket pipe over both pipes and thereby achieving good centering. After the actual welding has been carried out through the slots, the slots in the sleeve can also be welded to the pipe ends to increase the strength of the welded connection. The circumference of the socket pipe on which the slots are located is expanded by previous rolling so that it can accommodate a reinforced circular seam.

Die Erfindung ist in der Abbildung dargestellt. Die Rohre 1 und 2 sollen miteinander verschweißt werden. Zunächst wird das Muffenrohr 4 über die Verbindungsstelle geschoben. Das Muffenrohr 4 besitzt einen Schlitz 5, durch den hindurch die Schweißung unter beständiger Drehung des Rohres vorgenommen wird. Die Ründschweißnaht 3 kann dabei verstärkt werden, da die Erweiterung des Muffenrohres eine solche Verstärkung aufnehmen kann.The invention is shown in the figure. The pipes 1 and 2 should be together be welded. First, the socket pipe 4 is pushed over the connection point. The socket pipe 4 has a slot 5 through which the welding is carried out with constant rotation of the pipe will. The circumferential weld seam 3 can be reinforced because the expansion of the socket pipe provides such a reinforcement can accommodate.
