| titleOfInvention | Water pipe electric protection system |
| abstract | The present invention provides an anticorrosion system that keeps anticorrosion in a pipe in a constant state over a long period of time in an inner lining pipe in which a coating is applied to the inner face of a water pipe. An external power supply device having an anode terminal, a cathode terminal, and a reference electrode terminal, water pipes 4 and 5 electrically connected to the cathode terminal and coated with an inner surface lining film in a steel pipe, an anode The electrode 6 is electrically connected to the terminal and is electrically insulated from the water pipes 4 and 5 in the direction of the axis of the pipes 4 and 5 and electrically connected to the reference electrode terminal. And a reference electrode 7 that is arranged to be electrically insulated from the pipe wall from the pipe wall of the water pipe 4 into the pipe, and detects the potential of the cathode terminal with respect to the reference electrode terminal. The direct current voltage output from the anode terminal is controlled so that the potential becomes a predetermined potential, thereby preventing the corrosion of the iron exposed portions 12 and 13 in the water pipes 4 and 5.
