Description

fö Isoliertes Kaltwasserrohr mit Bunden und losen Flanschenfö Insulated cold water pipe with collars and loose flanges

Beschreibungdescription

Die Erfindung betrifft ein isoliertes Doppelmantel-Flanschenrohr wie es im Steinkohlenbergbau zum Transport von Kühlwasser verwendet wird.The invention relates to an insulated double-jacket flanged pipe as it is used in coal mining for the transport of cooling water is used.

Die bekannten Ausführungen hauen den Nachteil, daß Konstrukticnsbedingt der Bund an einem Rohrende nur einseitig von innen mit üem Druckrohr verschweißt werder kann.The known designs have the disadvantage that they are due to the construction the collar at one end of the pipe only on one side from the inside with uem Pressure pipe can be welded.

Das doppelseitige Verschweißen des Druckrohrs mit den Bunden an beiden Rohrenden ist jedoch aus sicherheitstechnischen Gründen erforderlich.The double-sided welding of the pressure pipe with the collars at both pipe ends is, however, for safety reasons necessary.

Um diesen Mangel zu beseitigen wird das Mantelrohr an einem Rohrende mittelbar über ein Schieberohr mit dem Bund verbunden. Der Bund des anderen Rohrendes wird direkt mit dem Mantelrohr verschweißt. Dadurch ist es mögiici., nach dem Verschweißen des Bundes mit dem Druckrohr an einem Rohrende, das Schieberohr über, oder unter das Mantelrohr zu schieben und die äußere zweite Schweißnaht zwischen Bund und Druckrohr am anderen Rohrende zu ziehen. Darnach wird das Schieberohr einerseits mit dem Bund, andererseits mit dem Mantelrohr verschweißt.To eliminate this deficiency, the jacket pipe is attached to a The pipe end is indirectly connected to the collar via a sliding pipe. The collar of the other end of the pipe is connected directly to the jacket pipe welded. This makes it possible, after welding the collar to the pressure pipe at one end of the pipe, the sliding pipe over, or to push under the jacket pipe and close the outer second weld seam between the collar and pressure pipe at the other end of the pipe draw. The sliding tube is then welded to the collar on the one hand and to the jacket pipe on the other.
