Popis: The state of art in alternating current (AC)-induced corrosion in pipelines is reviewed. Growing pipeline networks and their co-location with high-voltage (HV) transmission networks have brought into focus the issue of induced AC corrosion on the pipeline networks. Induced AC corrosion may quickly and severely affect the integrity of pipeline networks, especially considering that a number of such pipelines are transporting huge quantities of hazardous fluids. Any breach in pipeline integrity due to AC corrosion may result in disastrous consequences. In the last 30 years, it has been established that the induced AC corrosion can affect the buried pipeline integrity severely. During operations, the resistive as well as inductive coupling with transmission lines pose a significant risk of pipeline corrosion. The literature is reviewed to put together various issues and factors responsible for AC-induced corrosion in pipelines. The various publications on induced AC corrosion are reviewed to identify characteristics of AC-induced corrosion and major factors that determine the severity and impact of AC-induced corrosion. The areas have been identified wherein scope exists for additional studies on AC corrosion.
