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.

Flexible cryogenic conduit

The corrugation is removed from an end portion of a helically corrugated tube, and an internally threaded sleeve is threaded onto the tube. The sleeve has an unthreaded extension which is being drawn by a suitable tool to engage the smooth wall portion of the tube and is subsequently welded thereto.
