Abstract

PURPOSE:To keep change of temperature of fluid in a pipe small or keep temperature of fluid constant by covering a heat storage layer in which plastic resin is impregnated by latent heat storage member to liquid transportation pipe by extrusion and covering. CONSTITUTION:A heat storage layer 2 is mounted on the outer periphery of a pipe, and the pipe is constituted by mounting a protective coated layer 3 on the outer layer of the pipe 1 which protects the heat storage layer 2 from mechanical external force. The heat storage layer 2 is formed by winding latent heat storage member as tape, or by impregnating latent heat storage member in plastic resin such as polyethylene and extruding and covering it, or by putting latent heat storage member in a hollow glass capsule or plastic capsule, blending this capsule with plastic material and extruding and covering it. Consequently, it is possible to keep temperature of liquid constant and make change of temperature of liquid at outlet extremely small, even if temperature of liquid which flows in changes.
