Description
Verfahren zur Verbindung von Rohrenden mittelst Schweissen.
Die Erfindung betrifft ein Verfahren zur Verbindung von Rohrenden mittelst Schwei- Ben, insbesondere von Rohrenden, welche sich an schlecht zugänglichen Stellen befinden. Sie besteht darin, dass die Rohrenden so abgeschnitten, bezw. in der Weise anein andergefügt werden, dass eine Offnung übrig bleibt, durch welche ein Teil des Rohrumfanges von innen geschweisst wird, während die Öffnung nachher durch Einschweissen eines entsprechenden Stückes geschlossen wird. Die Erfindung bezweckt, infolge der dadurch erzielten Erleichterung ein exakteres und rascheres Arbeiten zu ermöglichen.
Das Verfahren ist auf der Zeichnung anhand der Fig. 1-3 beispielsweise'erläutert.
Fig. 1 zeigt die aneinandergefügten und zu verschweissenden Rohrenden von vorn,
Fig. 2 von der Seite, und
Fig. 3 zeigt die Rohrverbindung nach ihrer Fertigstellung in vergrössertem Massstab.
Die zu verschweissenden Rohrenden 1 und 2 (Fig. 1) befinden sich inmitten anderer Rohre 3,4 und 5, welche zum Beispiel längs einer Wand 6 angeordnet sind. Die Schweiss- stelle ist deshalb fast nur von vorn, d. h. von der der Wand abgekehrten Seite zu gänglich. Statt nun die Rohre längs des ganzen Umfanges von aussen zu schweissen, werden die Rohrenden an den Stellen 7 und 8 abgeschrägt, so dass eine Offnung übrig bleibt, durch welche der der Wand zuge kehrte Teil von innen her bequem geschweisst werden kann. Nachdem dieser Teil von innen her geschweisst worden ist, wird die Öffnung g nachher durch Einschweissen eines sektor ähnlichen Stückes 9, wie aus Fig. 3 ersichtlich, geschlossen.
Die gezeigte Verbindungsart von Rohrenden eignet sich namentlich zum Einfügen von Rohrstücken in schon vorhandene Rohrsysteme. Die zu ersetzende Stelle des Rohrsystemes wird herausgeschnitten und durch ein neues Rohrstück ersetzt, welches gemäss dem beschriebenen Schweissverfahren eingefügt wird.
Process for connecting pipe ends by means of welding.
The invention relates to a method for connecting pipe ends by means of welding, in particular pipe ends which are in poorly accessible places. It consists in the fact that the pipe ends are cut off, respectively. be joined together in such a way that an opening remains through which part of the pipe circumference is welded from the inside, while the opening is closed afterwards by welding in a corresponding piece. The aim of the invention is to enable more precise and faster work as a result of the relief achieved thereby.
The method is exemplified in the drawing with reference to FIGS. 1-3.
Fig. 1 shows the joined pipe ends to be welded from the front,
Fig. 2 from the side, and
Fig. 3 shows the pipe connection after its completion on an enlarged scale.
The pipe ends 1 and 2 to be welded (FIG. 1) are located in the midst of other pipes 3, 4 and 5 which are arranged along a wall 6, for example. The welding point is therefore almost only from the front, i. H. accessible from the side facing away from the wall. Instead of welding the pipes along the entire circumference from the outside, the pipe ends are beveled at points 7 and 8 so that an opening remains through which the part facing the wall can be conveniently welded from the inside. After this part has been welded from the inside, the opening g is subsequently closed by welding in a sector-like piece 9, as can be seen from FIG.
The type of connection shown for pipe ends is particularly suitable for inserting pipe sections into existing pipe systems. The part of the pipe system to be replaced is cut out and replaced with a new pipe section, which is inserted according to the welding process described.
