Abstract
Official abstract text for this publication.
Provided is a thermal-insulated multi-walled pipe for superconducting power transmission that highly prevents intrusion of external heat due to radiation and has excellent thermal insulation property without using a superinsulation and can be produced easily. A thermal-insulated multi-walled pipe for superconducting power transmission comprises: a superconducting cable; and a multi-walled pipe that houses the superconducting cable, wherein the multi-walled pipe is composed of a plurality of straight pipes, and at least one of the plurality of straight pipes has, at a surface thereof, a coating layer containing a metal powder.

The invention claimed is: 1. A thermal-insulated multi-walled pipe for superconducting power transmission, comprising: a superconducting cable; and a multi-walled pipe that houses the superconducting cable, wherein the multi-walled pipe is composed of a plurality of straight pipes, at least one of the plurality of straight pipes has, at a surface thereof, a coating layer containing a metal powder, and a content of the metal powder in the coating layer is 35 mass % to 98 mass %. 2. The thermal-insulated multi-walled pipe for superconducting power transmission according to claim 1 , wherein the metal powder is made of a metal having a sacrificial corrosion protection effect. 3. The thermal-insulated multi-walled pipe for superconducting power transmission according to claim 2 , wherein a thickness of the coating layer is 10 μm or more. 4. The thermal-insulated multi-walled pipe for superconducting power transmission according to claim 3 , wherein a resin coating layer is provided at an outer surface of an outermost straight pipe of the plurality of straight pipes. 5. The thermal-insulated multi-walled pipe for superconducting power transmission according to claim 2 , wherein a resin coating layer is provided at an outer surface of an outermost straight pipe of the plurality of straight pipes. 6. The thermal-insulated multi-walled pipe for superconducting power transmission according to claim 1 , wherein a thickness of the coating layer is 10 μm or more. 7. The thermal-insulated multi-walled pipe for superconducting power transmission according to claim 6 , wherein a resin coating layer is provided at an outer surface of an outermost straight pipe of the plurality of straight pipes. 8. The thermal-insulated multi-walled pipe for superconducting power transmission according to claim 1 , wherein a resin coating layer is provided at an outer surface of an outermost straight pipe of the plurality of straight pipes. 9. The thermal-insulated multi-walled pipe for superconducting power transmission according to claim 1 , wherein a material of the straight steel pipe is one or both of carbon steel and stainless steel.
