Abstract
Corrosion in facilities and equipment in the oil and gas industry can result to a loss of product containment and explosion, which ultimately lead to significant financial loss and environmental damage. One of the severe types of corrosion challenges that is pervasive particularly on pipeline facilities is corrosion under insulation (CUI). Most engineering materials are susceptible to most types of corrosion due to different environmental factors such as temperature, condensation, corrosive environment, flow regime and active-passive related parameters. Different types of corrosion are classified into different modes depending on these environmental factors. The purpose of insulating pipes varies on different systems to prevent heat loss or heat gain. The research shows that at least 85% of heat loss is reduced on the first inch of insulation and 95% of heat loss is reduced on several inches compared to what it would be from uninsulated surfaces. Insulation also acts as a protection to personnel, emissions reduction, condensation, freeze protection and noise reduction.
This study is primarily focused on investigating the failure analysis of corrosion under insulation (CUI) of piping components in oil and gas facilities. Based on available literature review, part of the investigation is about the material selection of different engineering materials used on piping components to at least mitigate or prevent CUI.
