Abstract
The interior of a tube provided for low temperature operation is shielded from the exterior through a plurality of metal ribbons helically looping around the tube in an intertwined relationship and each carrying a welded on conduit for low temperature liquid whereby one of these conduits serves as a primary or outgoing conductor, and the two others serve as return paths; suitable spacers are provided to position the system in a concentric relation; inner and outermost tubes are preferably corrugated and the immediate interior of the outermost tube is filled with superinsulation.
Claims5
A cryogenic tube system including at first corrugated tube, the interior of which is to be thermally isolated against the exterior at large;
- and
- a second, outer also corrugated tube concentrically arranged with respect to said inner tube, to establish a flexible assembly comprising:
- a plurality of metallic ribbons being of a flat cross-section and arranged helically in an intertwined relationship around said inner tube;
- a corresponding plurality of conduits for coolant affixed respectively to said ribbons, facing the outer tube and looping accordingly around said inner tube in a configuration of intertwined helices;
- and
- spacer means arranged with respect to the aforementioned assembly for supporting thereon said outer tube.
