Abstract

Die Erfindung betrifft ein Koaxialrohr oder eine oder Rohr-in-Rohr-Anordnung für die getrennte Leitung mindestens zweier Medien, deren Druckniveau sich unterscheidet, wobei bei dem Koaxialrohr (7) oder der Rohr-inRohr-Anordnung die Niederdruckseite in radialer Richtung näher der Mittellängsachse als die Hochdruckseite angeordnet ist.

Figure imgaf001
The invention relates to a coaxial tube or a tube-in-tube arrangement for the separate line of at least two media whose pressure level differs, wherein the coaxial tube (7) or the tube-in-tube arrangement, the low pressure side in the radial direction closer to the central longitudinal axis as the high pressure side is arranged.
