<P>PROBLEM TO BE SOLVED: To provide a water distribution pipe body and a scale deposition prevention method for preventing the scales from depositing on a pipe. <P>SOLUTION: The water distribution pipe body includes an outer pipe 1 and a scale deposition prevention layer 2 which is formed on the inner wall surface of the outer pipe 1. The scale deposition prevention layer 2 is a flow channel capable of expanding and contracting. The water distribution pipe body contains the flow channel 3 to be expanded and contracted by inflow and outflow of fluid in the flow channel 3. The scale deposition prevention layer 2 which contains the expandable/contractable flow channel 3 is formed on the inner wall of the pipe 1. The fluid is supplied into the flow channel 3 and/or the fluid is discharged out of the flow channel 3 to expand/contract the channel 3, thereby preventing the scales from depositing on the pipe 1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
