Flanschverbindung für Hochdruck-Doppelmantelrohre

摘要

The invention relates to a flange connection for double-jacket high-pressure pipes for use in the range of from 300 to 10000 bar, wherein in at least one of the two flange connections on the high-pressure pipe end the jacket pipe end is configured as a joint flange (22). Said joint flange is fixed on the periphery of the high-pressure pipe (11, 12) by means of a joint connection (18) which is adapted to assume any longitudinal forces acting in the axial direction of the high-pressure pipe. The joint flange is further provided with the required bores (16) for the studs (17).
