| Abstract: |
| This work presents a study on the use of cathodic protection as a measure against corrosion in pipelines. The cathodic protection, compliant with the API 5L standard, is implemented here by applying an impressed current, while carefully considering several essential variables, such as soil characteristics, the type and color of the pipeline material, as well as the placement and size of the anode. Therefore, it is crucial to optimize the location and values of anodic overflows or ground resistances to ensure a uniform distribution of potential across the entire structure. In this method, impressed current protection uses an auxiliary anode and an external direct current source to induce a current through the electrolyte and the pipeline, thus countering the resistance of the steel. This approach is advantageous as it allows for the adjustment of electrical characteristics, particularly current levels, to meet specific needs. The factors essential to the effectiveness of cathodic protection systems, which optimize the distribution of protection potential across the structure, largely depend on the precise management of ground resistances during anodic discharge, particularly the attenuation coefficient (α). These factors were studied, and the results obtained were presented and discussed based on their influence. |
