Claims

[Claims for Utility Model Registration] 1. A high-temperature, high-pressure piping that guides high-temperature, high-pressure fluid, including a thick-walled outer tube that supports the pressure of the high-temperature, high-pressure fluid, and a thin-walled outer tube that shields the heat of the high-temperature, high-pressure fluid. A fin is attached to the inner circumferential surface of the outer tube, and a fin capable of contacting the outer circumferential surface of the inner tube is attached to the inner circumferential surface of the outer tube. High-temperature/high-pressure piping characterized by forming a cooling fluid passage that guides cooling fluid of the same type as the high-pressure fluid, which has approximately the same pressure and is lower in temperature. 2. It has a connecting inner pipe interposed in the connecting part of the inner pipe,
2. The high-temperature/high-pressure piping according to claim 1, wherein a flange having a cooling fluid passage is provided on the outer peripheral surface of the inner pipe for connection, and the outer peripheral portion of the flange is interposed in the connecting portion of the outer pipe.
