ABSTRACT:
A system for preventing corrosion of a metallic surface in an environment in which a corrosive condensate with a pH of less than about 3 tends to form on the surface exposed to the environment. The system includes an absorbent lining formed from a concrete material that has a chemical resistance to a low pH and that increases the pH of the environment at the underlying metallic surface. The system further includes a counterelectrode and an electrochemical potential control means connected in electrical circuit with the metallic surface. An electrical potential is maintained upon the metallic surface sufficient to effect cathodic protection.
