Petrobras Transporte S.A. – Transpetro Solution for the Minimization of External Corrosion of Thermal Insulated Pipelines for Underground Heated Oil Transportation in Brazil
Abstract:Underground heated oil transportation within the processes of Petrobras/Transpetro is a critical issue because of the need to maintain the temperature of the oil in the pipeline network from the point of origin to destination with as little heat loss as possible. Insulated pipelines using polyurethane rigid foams as insulation have been used for many years for this transportation process. However, instrumentation inspections have shown a severe external corrosion process in some insulated pipelines after a num… Show more
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.
