Abstract

In order to better understand the corrosion risk of single pole operation of high-voltage direct current (HVDC) grounding electrodes on pipelines, a comprehensive review of corrosion monitoring technologies for buried pipelines over recent decades was conducted in this paper; the principles of various corrosion monitoring techniques were introduced, and the application status of different corrosion monitoring technologies in the context of HVDC interference with buried pipelines was summarized; the advantages and disadvantages of four rapid corrosion measurement methods, namely the field burial method, intelligent pile monitoring method, electrochemical reduction (ER) corrosion rate probe method and laboratory simulation experiments, in evaluating the corrosion rate of buried pipelines under HVDC interference were mainly analyzed. Based on this analysis, recommendations for the application of various corrosion monitoring techniques in the field of HVDC interference with buried pipelines were proposed. Additionally, new directions in monitoring technology for corrosion rate of buried pipelines under HVDC interference were explored, providing references for relevant researchers and engineers.
