Description

DEUTSCHESGERMAN

Die Erfindung bezieht sich auf eine Rohrverbindung für Rohre mit Kunststoffauskleidung, bei der die Rohrenden mit kegeligen Außengewinden in entsprechend hohlkegelige Innengewinde einer Muffe eingreifen und die Muffe zwischen den Gewindeabschnitten eine in die Muffenwand eingelassene Kunststoffhülse enthält. Sie bezweckt Verbesserungen, wodurch verhindert wird, daß im Bereich der Verbindung das durch die Rohre fortzuleitende Medium mit metallischen Flächen, insbesondere mit den Gewindeflächen, in Berührung kommt, um auf diese Weise insbesondere die Gewindefläche gegen Korrosion zu schützen. Diese Aufgabe tritt z. B. bei ölfeldrohren auf.The invention relates to a pipe connection for pipes with plastic lining, in which the Pipe ends with tapered external threads engage in correspondingly hollow-tapered internal threads of a socket and the sleeve contains a plastic sleeve embedded in the sleeve wall between the threaded sections. It aims to improve, thereby preventing that in the area of the connection the medium to be conveyed away from the pipes comes into contact with metallic surfaces, in particular with the threaded surfaces comes to protect in particular the thread surface against corrosion in this way. These Task occurs z. B. on oil well pipes.

Erfindungsgemäß ist die Kunststoffhülse mit Muttergewinde versehen, mit dem zwei die Stirnflächen der Rohrenden abstützende Schraubringe aus Kunststoff zusammenwirken. Die Schraubringe werden in der Kunststoffhülse so eingestellt, daß ein fester Sitz der Stirnflächen der Rohre gegen diese Ringe nach dem Anziehen der Rohrverbindung gewährleistet ist. Dadurch wird ein dichter Abschluß der metallischen Gewindeflächen der Rohrenden und der Muffe gegenüber dem Rohrinnern erzielt. Zweckmäßig ist jedes Rohrende mit einer den Übergang zwischen dem kegeligen Außengewinde und der Stirnfläche bildenden Kegelfläche versehen, deren Kegelwinkel größer ist als der Kegelwinkel des Gewindeteiles. According to the invention, the plastic sleeve is provided with a nut thread with which the two end faces the pipe ends supporting screw rings made of plastic cooperate. The screw rings are set in the plastic sleeve so that a tight fit of the end faces of the tubes against them Rings after tightening the pipe connection is guaranteed. This creates a tight seal achieved the metallic thread surfaces of the pipe ends and the socket opposite the inside of the pipe. Appropriate each pipe end has a transition between the tapered external thread and the face forming conical surface, the cone angle is greater than the cone angle of the threaded part.

Ein Ausführungsbeispiel ist in der Zeichnung im axialen Schnitt dargestellt.An embodiment is shown in the drawing in axial section.

Die zu verbindenden Rohre 1 und 1', welche mit einer Kunststoffauskleidung 2 bzw. 2' versehen sind, besitzen an den Enden kegelige Außengewinde, auf welche die Muffe 3 mit entsprechend hohlkegeligen Innengewinden aufgeschraubt ist. In die Muffenwand ist zwischen den hohlkegeligen Gewinden eine mit Muttergewinde versehene Kunststoffhülse 4 eingelassen. In diese Kunststoffhülse 4 sind zwei Schraubringe 5 und 5' eingeschraubt, gegen die sich die Stirnflächen der Rohrenden nach dem Anziehen der Rohrverbindung fest abstützen. Jedes Rohrende ist mit einer den Übergang zwischen dem Gewinde und Rohrverbindung für Rohre
mit KunststoffauskleidungThe pipes 1 and 1 'to be connected, which are provided with a plastic lining 2 or 2', have conical external threads at the ends, onto which the sleeve 3 is screwed with correspondingly hollow-conical internal threads. A plastic sleeve 4 provided with a female thread is let into the socket wall between the hollow-conical threads. Two screw rings 5 and 5 'are screwed into this plastic sleeve 4, against which the end faces of the pipe ends are firmly supported after the pipe connection has been tightened. Each pipe end has a transition between the thread and pipe connection for pipes
with plastic lining
