Abstract: To provide a thermal insulation piping with no radially projecting part from a periphery thereof, so as to facilitate insertion of the thermal insulation piping into a pipeline or equivalent. In a thermal insulation tube 10 having a vacuum layer between an inner tube 11 and an outer tube 12, an evacuation port 30 for vacuum evacuation is oriented parallel with a longitudinal direction of the thermal insulation piping at an end of the thermal insulation tube 10. This construction can produce the thermal insulation tube 10 with no radially projecting part from a periphery thereof, thus providing improved workability when the thermal insulation piping is contained in the pipeline or equivalent. Further, a flexible pipe(s) 40 is/are preferably connected to the evacuation port(s) 30. This can allow increased positional tolerances in the connection of the evacuation port(s) to a vacuum evacuation device.

Abstract: A baking method for heating an object (an inner pipe, an outer pipe) having a vacuum layer formed therein to remove gas molecules occluded in the object, wherein the object itself is made to be a heat production element for heating. By making the baking object a heat production element, the object can be heated directly and the heating can be energy-efficient. Moreover, additional heating means such as a heater or gas is unnecessary, which enables simplification of a configuration of a baking device. Therefore, a baking method is obtained which enables energy-efficient heating and, in particular, uniform heating of a long or large object.

Abstract: A superconducting cable is manufactured by providing spacers 12 in a plurality of cores 2 at the time of stranding of the cores 2, and removing the spacers 12 before the stranded cores 2 are housed in a thermally insulated pipe and housing the cores into the thermally insulated pipe while the strands are held in a slacked state. By means of temporal interposition of the spacers, there is easily manufactured three cores having sufficient slack to manage thermal contraction which occurs when the cores are cooled in the thermally insulated pipe.
