Summary: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.
