This report refers to the activities performed in the frame of PRCI project on the refinement of the AC corrosion criteria by evaluating real-world pipeline AC corrosion cases and applying an improved AC corrosion prediction model.
The diagrams of AC corrosion likelihood assessment in the standard ISO18086:2015 was used as a starting point. Correlations between field data (especially those provided through dig reports from AC corrosion anomalies) and the simulation results for different CP polarization levels, AC induced voltage, soil conditions (texture, soil resistivity and moisture) and coating...
The diagrams of AC corrosion likelihood assessment in the standard ISO18086:2015 was used as a starting point. Correlations between field data (especially those provided through dig reports from AC corrosion anomalies) and the simulation results for different CP polarization levels, AC induced voltage, soil conditions (texture, soil resistivity and moisture) and coating defect properties (size and thickness) were investigated.
The final goal is achieving a further refinement of the proposed AC corrosion criteria in previous project (EC-6-2) based on long-term AC corrosion behavior.
