Abstract
To provide, using simplified costly system, corrosion protection method and apparatus for (electrically) protecting a metal structure such as a metal roof of a building exposed to the atmosphere or a metal equipment such as a metal water service pipe from being corroded. Mounting an anode at periphery of one side of a metal equipment (or a metal structure); connecting a cathode to a main body of the metal equipment (or the metal structure) being alienated from the anode; whereby when water film is formed on the side of the metal equipment (or the metal structure), establishing a corrosive condition of the metal equipment (or the metal structure), a current is automatically flowed between the anode and the cathode to prevent corrosion of the metal equipment (or the metal structure).
