Description
Verfahren zum Verbinden von Rohren mittelst Schweissen. Die Erfindung bezieht sich auf eine Er gänzung des durch das ,. Hauptpatent ge schützten Verfahrens zum Verbinden von Rohren mittelst Schweissen, bei welchem das eine Rohrende mit einem Bördelrand, das andere mit einer Ausweitung versehen, der Bördelrand"gegen die Ausweitung gestossen, ein frei vorstehender Rand des ausgeweiteten Rohrendes über den Bördelrand umgekantet und die Verbindungsstelle dicht verschweisst wird.
Das im Hauptpatent erläuterte Verfahren gestattet keine Verschwenkung der Rohre beim Verlegen der Leitungen was zuweilen als bZangelj empfunden wird.
Gemäss der zusätzlichen Erfindung ;sind die Ausweitung am einen und der Bördel- rand am andern Rohrende nach einer Kugel fläche gekrümmt. und ist genügend Spielraum vorhanden, um vor dem Verschweissen eine Verschwenkung der Rohre zu gestatten. Die Abbildung betrifft ein Ausführungs beispiel des Erfindungsgegenstandes und gibt einen Schnitt durch eine Seite von zwei Rohrenden wieder, die nach dem Verfahren gemäss der Erfindung verbunden werden sol len.
Der kugelige Bördelrand b des einen Rohrendes liegt bei gerader Verlegung an der ebenfalls nach einer Kugel gekrümmten Ausweitung c an in der Stellung a-a, bei Schwenkung nach o rückt der Bördelrand gegen den Rand der Ausweitung, bei Schwen kung nach u um ein bestimmtes Mass davon ab. Nach Fixierung der Rohre wird der überstehende Rand über den Bördelrand abgekantet und verschweisst gemäss dem im Hauptpatent beschriebenen Verfahren.
Process for connecting pipes by welding. The invention relates to an addition to the by the. Main patent protected method for connecting pipes by means of welding, in which one pipe end is provided with a flanged edge, the other with a widening, the beaded edge "butted against the widening, a protruding edge of the expanded pipe end folded over the beaded edge and the connection point tight is welded.
The method explained in the main patent does not allow the pipes to be swiveled when laying the lines, which is sometimes perceived as bogus.
According to the additional invention, the widening at one end of the tube and the flanged edge at the other tube end are curved according to a spherical surface. and there is enough clearance to allow the tubes to pivot before welding. The figure relates to an embodiment example of the subject matter of the invention and shows a section through one side of two pipe ends which are to be connected according to the method according to the invention.
When laid straight, the spherical flanged edge b of one end of the pipe lies on the expansion c, which is also curved towards a ball, in position aa; when pivoted to o, the flanged edge moves towards the edge of the expansion, when pivoted to u by a certain amount . After fixing the pipes, the protruding edge is folded over the flange and welded according to the method described in the main patent.
