Abstract
A cathodically protected storage structure, such as a liquid manure storage tank. The structure comprises a generally cylindrical shell formed of steel plate sections which is mounted on a support or foundation. The steel plate sections are coated with a corrosion resistant material, such as glass, and are bolted together at their overlapping joints. A group of anodes, formed of a metal electropositive to steel, are mounted within the structure, and electrical leads, which are connected to the anodes, pass through bolt holes in the wall of the structure and are connected on the outside of the structure to the metal plate sections. As the anodes are electropositive with respect to the steel plate sections, the anodes will corrode preferentially to thereby protect the steel against corrosion.
