An extension approach to estimate soil corrosivity for buried pipelines

Context-Based and Image-Based Subsea Pipeline Degradation Monitoring

“…The physical features of soil significantly contribute to the corrosion propagation of buried metals, which is particularly apparent in pipelines. Wang et al [1] perfromed the soil corrosivity tests that most commonly analyze oxidation potential, pH factor, water content, and salt saturation. According to the National Association of Corrosion Engineers and the American Society for Testing and Materials, the degradation process of pipeline materials is considerably determined by soil resistivity and corrosivity [1].…”

According to the National Association of Corrosion Engineers and the American Society for Testing and Materials, the degradation process of pipeline materials is considerably determined by soil resistivity and corrosivity [1]. Additionally, the authors [1] examined data mining, artificial intelligence, and machine learning approaches to analyze large amounts of sensor-collected soil data and determine soil composition and corrosivity.…”

“…Material degradation of a pipeline can result in structural failures that endanger marine life, create environmental hazards, and cause significant financial losses. Understanding the factors contributing to corrosion is essential for understanding the development of corrosion in materials, building anti-corrosion structures, and making risk assessments during monitoring and inspection operations [1]. Several factors contribute to the deterioration of pipeline surface material, and there are multiple factors to consider when identifying the most effective ways to predict deterioration and ultimately prevent substantial damage.…”

Corrosion behavior and mechanism of X80 steel in silty soil under the combined effect of salt and temperature

“…The failure that occurs during the service life of pipelines can be broadly divided into the following three categories: excavation damage, material defects, and corrosion effects. 9–12 Inhomogeneous and porous soil cause relatively complex corrosion of buried pipeline steel, based on the interaction of multiple simultaneous reactions. As a result, the direct contact between the steel surface and the erosive soil environment is regarded as a significant cause of its corrosion failure.…”

“…As a result, the direct contact between the steel surface and the erosive soil environment is regarded as a significant cause of its corrosion failure. 9,13 Previously, extensive research efforts have been devoted to the study on the electrochemical corrosion reaction at the soil–steel interface, 14–17 and a more mature theory has been established. Most of the reactions correspond to oxygen-depolarized corrosion.…”
