As described above, according to the embodiment of the present invention, since the heat insulating material 2 and the heat insulating pipe 3 having the heat insulating coating layer 31 formed on the outer circumferential surface are installed around the main pipe 1 through which the object is transported, it is related to the external temperature change. The temperature of the object to be transferred can be kept constant at all times, and through this, deformation of the object can be prevented.

In addition, a heat insulating part 4 is disposed around the main pipe 1 and a working fluid 4A having a set temperature flows. 5) and the heating unit 6 are disposed, so that the heat insulating property of the pipe can be maximized.

In addition, since the heat insulating unit 4, the cooling unit 5, and the heating unit 6 are formed in individually controllable modules, the insulation efficiency can be selectively adjusted according to the external temperature or object.
