Abstract

PURPOSE: To prevent the crevice corrosion of heating pipe in contact with static water by feeding into the pipe a sacrifice anode metal powder and a salt solution thereof, during when the heat exchanger is off operation, and conducting electrolysis so as to form an electrode position layer of the metal on the inside surface of the pipe.
