| Abstract | ||
| Cathodic protection technologies proved for more than a century until now their effectiveness in protecting metal objects containing fluids and buried in an electrolytic medium against the electrochemical corrosion process. This work aims to design and evaluate performance of an impressed current cathodic protection system. The system consists of a DC power source, and a group of electrodes (anodes), the resulting electrical circuit balances the natural potential that exists between the surrounding medium and the protected structure metal. This work presents a direct method to design a cathodic protection system for the cooling water pipeline for AL-Quds gas power station. Pipeline specification, type of coating and the soil which it buried within along its route were considered in the calculations of the desired protection current plus the standard allowances to ensure the proper performance of the cathodic protection system for at least twenty years. Measurement results proved the effectiveness of the cathodic protection system to keep the used pipeline negative potential within the international applicable standards. | ||
