The invention discloses a double-vacuum superconducting tube based on metal tubes. The double-vacuum superconducting tube comprises a first outer tube body, a second outer tube body, a nano metal barand sealing plugs. A superconducting chamber is arranged inside the first outer tube body. The sealing plugs are arranged at the two ends of the first outer tube body separately to make the superconducting chamber of the first outer tube body form an enclosed space. The superconducting chamber is sequentially divided into a vacuum layer and a superconducting fluid layer from top to bottom. The second outer tube body is embedded into the center of the superconducting fluid layer. A silica gel heating line is tightly wound onto the nano metal bar and penetrates through wire holes in the sealingplugs. The silica gel heating line is further connected with flexible conductors arranged outside the corresponding sealing plugs. A vacuum chamber is arranged at the center of the second outer tube body. The first outer tube body and the second outer tube body are both the metal tubes. According to the double-vacuum superconducting tube based on the metal tubes, the double-tube mode is adopted, and the second outer tube body is embedded into superconducting fluid in the first outer tube body, the temperature can be quickly transferred onto the pipe walls through the superconducting fluid andheat is transferred onto the ground; and meanwhile the metal tubes are adopted, the heat transfer speed is high, preheating time is short and thermal efficiency can reach the limit rapidly.
