description | Buried pipelines for gas and oil are protected by an insulation coating and a Cathodic Protection (CP). However, neighbouring high voltage HV power lines induce an alternating current AC which causes corrosion damages on metallic structures, even in CP conditions, this phenomenon is known as the AC corrosion. In our study, we conducted a substantial theoretical research in this field to explain the basic electrical and electrochemical mechanisms of corrosion by AC. Afterwards; we performed numerical simulation studies of the electrochemical reactions involved in the corrosion, such as the anodic and cathodic processes, i.e., the iron oxidation and reduction of both oxygen and hydrogen. We also simulated the CP, AC corrosion, and deformation of the steel pipeline sample. Finally, in order to remedy this problem, we developed a monitoring and correction program for optimising the AC corrosion. In this article, we presented the study of the chemical behaviour of iron, oxygen and hydrogen. Moreover, we applied the rectification program, which did never exist in previous studies. |
