Non-intrusive, electric field based equipment offers the possibility of monitoring pipelines for internal corrosion over the lifetime at selected positions. The paper presents a method for calculating the corrosivity along the pipeline and to find optimum positions for corrosion monitoring. Examples of case studies on pipelines carrying wet and dried gas are presented.
