<p><P>PROBLEM TO BE SOLVED: To maintain the high workability of a piping arrangement and an excellent freeze prevention function of a corrugated flexible pipe and a fluid pipe by restraining the lowering of the bending performance of the corrugated flexible pipe itself even though a heater source is arranged as much as possible due to the reasonable arrangement remodeling in the corrugated flexible pipe: to make it possible to downsize in radial direction, lower the production cost and restrain also the occurrence of the collision sound effectively due to ruffling of the fluid pipe originated from the water hammer phenomenon. <P>SOLUTION: Beside a flexible synthetic resin demarcating wall part 4 for heat radiation which demarcates a passage to pass a heat generation source 3 against a passage 4 to insert the fluid pipe in a sealing condition is formed integrally along a pipe shaft center in a protruding condition to the side of pipe shaft center on the wall 1b in the pipe of the corrugated flexible synthetic resin pipe 1, the flexible support body 5 of synthetic resin which can touch with the fluid pipe 1 to be inserted into a passage S1 for the fluid pipe insertion is formed and protruded integrally on the side of a pipe shaft center to the part which is biased toward the circumference from the demarcating wall part 4 for heat radiation in a wall face 1b within the pipe. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
