Description
Verfahren zur Herstellung einer Rohrverbindung und zur Ausübung des Verfahrens dienende Verbindungsmuffe Rohrverbindungsmuffen aus Kunststoff sind bekannt. Diese werden speziell zur Verbindung von Rohren zur Leitung aggressiver lledien benötigt und bedingen ein kompliziertes Befestigungs-und Abdichtungsver- falren.
Die vorliegende Erfindung betrifft nun ein Verfahren zur Herstellung einer Rohrverbindung unter Verwendung einer Verbindungsmuffe aus Kunststoff, insbesondere thermoplastischem Kunststoff, wie Cellulosederivate, Polyvinylehlorid, Ultramideo, Lu- polen (eingetragene blarken), Polystyrol, Polyamide, Polyäthylene usw.
Das Verfahren besteht darin, dass die Muffe vor dem Ge brauch in ein Bad, bestehend aus einer das Aufquellen der Muffe bewirkenden Flüssigkeit gebraeht und naeh Erreiehung eines durch Aufquellen vergrösserten Innendurchmessers auf die zu verbindenden Rohrenden aufge steekt wird, auf welchen die Sehrumpfung und Erhärtung der Muffe durch Verflüchti- gung der im Bad aufgenommenen Stoffe sich vollzieht, wobei eine hermetisch dichtende Umsehliessung der Rohrenden durch die Aluffe erreieht wird.
Bei der zur Herstellung der Rohrverbin- dung dienenden Rohrmuffe ist gemäss der Erfindung der Innendurchmesser kleiner als der Aussendurchmesser der beiden miteinander zu verbindenden Rohrenden. Diese Rohrmuffe kann als gerade Muffe, Winkel- bogenmuffe, T-Stückmuffe, Reduktionsmuffe usw. ausgebildet sein.
In der Zeichnung sind beispielsweise Aus führungsformen des Erfindungsgegenstandes dargestellt, und zwar zeigt :
Fig. 1 eine Ausführung der Muffe als gerades Verbindungsstüek,
Fig. 2 eine Ausführungsform der Muffe als Winkelstüek,
Fig. 3 eine Ausführungsform der Muffe als T-Stüek und
Fig. 4 bis 6 eine Reduktionsmuffe vor dem Bad, nach dem Bad sowie in montiertem Zustande nach der Schrumpfung und Erhärtung auf den Rohrenden.
Die in den Fig. 1 bis 4 dargestellten Verbindungsmuffen sind beispielsweise aus Poly äthylen oder einem andern Kunststoff hergestellt. Sie weisen in ihrem Innendurchmes- ser gegenüber den zu verbindenden Rohrenden etwa 20 /o Untermass auf, das heisst die lichte Weite der Verbindungsmuffe muss kleiner sein, als der Aussendurchmesser der zu verbindenden Rohrenden.
Diese Kunststoffmuffen werden im Sinne des Verfahrens zur Herstellung einer Rohrverbindung vor dem Gebraueh, das heisst vor der Montage in ein Bad aus Methylenchlorid oder Azeton eingelegt, bis sie beispielsweise Un'113 ihres ursprünglichen Innendurchmes- sers durch Aufquellen grosser geworden sind.
Bei diesem Bad wird der Kunststoffmuffe während des Aufquellens der Weichmacher entzogen. Die aufgequollene Muffe wird aus dem Bad herausgenommen und kann nun leicht auf die zu verbindenden Rohrenden aufgesteekt werden. Durch Verdunsten des von der Kunststoffmuffe während des Bades auf genommenen Methylenehlorides bzw. Azetons schrumpft die Muffe, indem sie die Rohrenden mit zunehmender Spannung umschliesst, auf ihr ursprüngliches Volumen zusammen, wobei sie sieh infolge Fehlens des Weichmachers erhärtet. Durch die bei der Schrumpfung erzeugte Spannung in der Umschliessung der Rohrenden wird eine vollkommende Dichtung der Rohrverbindung sowie ein überraschend fester Halt der Rohrenden in der Muffe erzielt.
Die durch den Entzug des Weieh- machers bewirkte zusätzliehe Erhärtung trägt noch erheblich bei zur Erhaltung einer stabilen Rohrverbindung.
Je nach der Art des für die Muffe verwendeten Kunststoffes ist auch eine entspre chende, das Aufquellen der Muffe bewirkende Flüssigkeit für das Bad zu verwenden. Dabei ist der Entzug des Weichmachers von sekun- därer Bedeutung.
Bei der Ausführungsform nach Fig. 1 handelt es sieh um eine gerade Verbindungsmuffe 1 von üblieher Form, in deren Hohlraum in der Mitte ein ringförmiger Rohranschlag 2 aus Metall, Kork oder Kunststoff vorgesehen ist. Der Rohranschlag kann auch aus gleichem Material wie die Muffe und aus einem Stüek mit derselben bestehen, wie dies bei der win kelförmigen Rohrmuffe in Fig. 2, bei der T-formigen Rohrmuffe in Fig. 3 sowie auch bei der Reduktionsmuffe in Fig. 4 bis 6 der Fall ist. Die Rohre 3 stossen satt an den Rohranschlag 2 an.
Bei der Reduktionsmuffe gemäss den Fig. 4 bis 6 ist in Fig. 5 die Muffe in aufgequollenem Zustande unmittelbar naeh dem Bade veranschaulicht.

Process for producing a pipe connection and connecting sleeve used for carrying out the method Pipe connecting sleeves made of plastic are known. These are specifically required for connecting pipes for conducting aggressive oil and require a complicated fastening and sealing procedure.
The present invention relates to a method for producing a pipe connection using a connecting sleeve made of plastic, in particular thermoplastic material, such as cellulose derivatives, polyvinyl chloride, ultramideo, lupoles (registered blarks), polystyrene, polyamides, polyethylene, etc.
The method consists in that the socket is brewed in a bath consisting of a liquid that causes the socket to swell before use and, after an internal diameter enlarged by swelling, is attached to the pipe ends to be connected, on which the swelling and hardening of the Sleeve takes place through the evaporation of the substances absorbed in the bath, whereby a hermetically sealed enclosure of the pipe ends is achieved by the aluminum sleeve.
In the case of the pipe socket used to produce the pipe connection, according to the invention, the inside diameter is smaller than the outside diameter of the two pipe ends to be connected to one another. This pipe socket can be designed as a straight socket, elbow socket, T-piece socket, reduction socket, etc.
In the drawing, for example, embodiments of the subject matter of the invention are shown, namely:
Fig. 1 shows an embodiment of the sleeve as a straight connecting piece,
Fig. 2 shows an embodiment of the sleeve as an angle piece,
Fig. 3 shows an embodiment of the sleeve as a T-piece and
4 to 6 show a reduction sleeve before the bath, after the bath and in the assembled state after the shrinkage and hardening on the pipe ends.
The connecting sleeves shown in Figs. 1 to 4 are made for example of poly ethylene or another plastic. In terms of their inner diameter, they are about 20% undersize compared to the pipe ends to be connected, that is to say the inside diameter of the connecting sleeve must be smaller than the outer diameter of the pipe ends to be connected.
In the sense of the process for producing a pipe connection, these plastic sleeves are placed in a bath of methylene chloride or acetone before use, that is to say before assembly, until, for example, their original internal diameter has increased due to swelling.
In this bath, the plasticizer is removed from the plastic sleeve while it swells. The swollen sleeve is taken out of the bath and can now be easily attached to the pipe ends to be connected. The evaporation of the methylene chloride or acetone absorbed by the plastic socket during the bath causes the socket to shrink to its original volume by enclosing the pipe ends with increasing tension, whereby it hardens due to the lack of the plasticizer. As a result of the tension generated in the enclosure of the pipe ends during the shrinkage, a complete seal of the pipe connection and a surprisingly firm hold of the pipe ends in the socket is achieved.
The additional hardening caused by the withdrawal of the softener still contributes significantly to maintaining a stable pipe connection.
Depending on the type of plastic used for the sleeve, a corresponding, the swelling of the sleeve causing liquid to be used for the bath. The removal of the plasticizer is of secondary importance.
The embodiment according to FIG. 1 is a straight connecting sleeve 1 of usual shape, in the cavity of which an annular pipe stop 2 made of metal, cork or plastic is provided in the middle. The pipe stop can also be made of the same material as the sleeve and of one piece with the same, as in the case of the angled pipe socket in Fig. 2, the T-shaped pipe socket in Fig. 3 and also the reduction socket in Fig. 4 to 6 is the case. The tubes 3 abut the tube stop 2 snugly.
In the case of the reduction sleeve according to FIGS. 4 to 6, FIG. 5 shows the sleeve in the swollen state immediately after the bath.
