Research on corrosion management technology of petroleum pipeline and pressure vessel

Abstract

At present, the corrosion management of the upper module pressure vessel and pressure pipeline of the fixed oil production platform and the floating production oil storage and unloading platform lacks localized corrosion rate knowledge base, corrosion mechanism knowledge base and inspection case knowledge base, resulting in low accuracy of evaluation results and the foundation of integrity management is weak. Based on this background, the paper discusses the leading causes of the corrosion process and studies and analyses the primary mechanism. Through careful consideration of pressure vessel design, material selection, manufacturing, coating and slow release and other factors, combined with different corrosion mechanisms, a comprehensive analysis of the corrosion protection of pressure vessels is carried out to find the best method of corrosion protection and corrosion control to ensure Pressure vessels operate safely and typically in petrochemical production.
