Abstract. Electric field induced in the Brazil–Bolivia pipeline was calculated using a distributed source line transmission (DSLT) theory during several space weather events. It was made with using geomagnetic data collected by a fluxgate magnetometer located at São José dos Campos (23.2º S; 45.9º W). The total corrosion rate was calculated with using the Gummow (2002) methodology and based in the assumption of 1-cm hole in pipeline coating. The calculations were performed for the ends of pipeline, where the largest out of phase pipe-to-soil potential (PSP) variations were obtained. The variations in PSP during the 17 March 2015 magnetic storm have led to the greatest corrosion rate of the analysed events. All the space weather events evaluated with high terminating impedance in this paper have contributed to increase the corrosion process. The applied technique can be used to evaluate the metal loss due to the high telluric activity associated with the geomagnetic storms at specific locations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
