Corrosion Detection and Protection Strategy for a Seawater Cooling Tower in a Thermal Power Plant

Visual inspection, thickness and adhesion testing of concrete protective coating as well as concrete reinforcement corrosion potential and concrete resistivity tests were used to inspect and analyze the corrosion condition of a seawater cooling tower in a thermal power plant. The results showed that the corrosion situation of the seawater cooling tower in different heights had obvious differences. The corrosion reasons in different areas were analyzed, the law of seawater cooling tower corrosion was summed up, and the corrosion level was scaled according to relevant standards. A seawater cooling tower corrosion control strategy was put forward, which can reduce the long-term costs of power plant cooling tower corrosion control.
