Isoliertes Rohr mit SchraubverbindungInsulated pipe with screw connection

BeschreibungDescription

Die Erfindung betrifft ein isoliertes Doppelmantelrohr mit Schraubverbindung wie es insbesondere im Bergbau Untertage zum Transport von gekühlten und/ oder erwärmten Medien verwendet wird.The invention relates to an insulated double-walled pipe with a screw connection as is used in particular in underground mining for the transport of cooled and/or heated media.

Derzeit werden isolierte Rohre als Doppelmantel-Flanschenrohre mit PUR-Hartschaumisolierung eingesetzt.Currently, insulated pipes are used as double-walled flange pipes with PUR rigid foam insulation.

Bei den bekannten Ausführungen ist das Mantelrohr an beiden Rohrenden konisch eingezogen um an die dem Innenrohr entsprechenden genormten Baumaße von Bund und Flansch anzuschließen.In the known designs, the jacket pipe is tapered at both pipe ends in order to connect to the standardized dimensions of the collar and flange corresponding to the inner pipe.

Der Isolierraum ist wasserdicht verschweißt dadurch daß das Innenrohr über Vorschweißbördelringe mit den Druckringen verschweißt ist und diesemit dem Mantelrohr.Die beiden lose hinter den Druckringen liegenden Flansche werden miteinander verschraubt.The insulation chamber is welded watertight by welding the inner pipe to the pressure rings using pre-welded flange rings and then to the jacket pipe. The two flanges lying loosely behind the pressure rings are screwed together.

Die Erfindung hat sich die Aufgabe gestellt, ein isoliertes Rohr mit einer schnell lösbaren Verbindung zu schaffen, das bessere Isoliereigenschaften aufweist als die bekannten Ausführungen von Doppelmantel-Flanschenrohren.The invention has the object of creating an insulated pipe with a quick-release connection that has better insulating properties than the known designs of double-walled flange pipes.

Erfindungsgemäß wird dies dadurch gelöst,daß durch Verachrauben der lose hinter den Druckringen liegenden Schraubmuffe und Schraubring, die Vorschweißbördelringe gegen die Gujnmi-Fiachdichtung gepresst werden.According to the invention, this is solved by screwing the screw sleeve and screw ring loosely behind the pressure rings together, pressing the weld-on flange rings against the Gujnmi flat seal.

Schraubmuffe und Schraubring sind mit Montagehilfen-Nocken oder Bohrungen-versehen.The screw sleeve and screw ring are provided with cams or holes to aid assembly.

Das Mantelrohr ist über uie gesamte Baulänge zylindrisch ausgeführt.Durch die, bis zum Rohrende konstante Isolierdicke und die, im Vergleich zur Flanschverbindung kleine Masse der Schraubverbindung hat das System bessere Isoliereigenschaften als die bekannten Ausführungen mit Flanschverbindung.The jacket pipe is cylindrical over its entire length. Due to the constant insulation thickness up to the end of the pipe and the small mass of the screw connection compared to the flange connection, the system has better insulation properties than the known versions with flange connections.
