Since the temperature of the fluid decreases quickly when activated, the heating device is either reheated before transportation is restarted, or the heating device is constantly activated even during the unavoidable interruption, which is a problem from an energy-saving perspective.

On the other hand, the heat of the heating device 4 and/or the heat of the fluid being transported is stored in the latent heat storage material JiS. When the heating device 4 is stopped, such as when fluid transportation is interrupted, the heat stored in the heat storage material N5 is
It is discharged into the fluid through the inner tube 2 to moderate the temperature drop of the fluid.

スが少なくなる。(Effects of the Invention) The present invention has a heat insulating material layer concentrically formed on the outer circumferential side and a latent heat storage material layer on the inner circumferential side between the inner tube and the casing tube, and a Since the fluid heating device is provided close to the pipe, the heat released from the heating device and the fluid during fluid transportation is efficiently stored in the heat storage material layer, reducing heat loss in the fluid heating device.

大きい。In addition, when the heating device is stopped, the heat stored in the heat storage material layer is released back and the temperature drop of the fluid can be alleviated. Therefore, when the fluid is being transported intermittently, if the interruption is within the allowable time, the fluid can be transported without reheating. Transportation can be resumed. Therefore, by intermittently operating the heating device, it is possible to control the device economically, achieve efficient fluid transport, and have a significant energy saving effect.

に用いて有益である。Further, since heat is radiated from the heat storage material layer from the entire circumference of the inner tube, the temperature of the fluid can be efficiently maintained. Therefore, the present invention is useful for heat-retaining tubes used for heat-retaining transportation of high-viscosity fluids such as heavy oil and paraffin.
