Corrosion Under Insulation (CUI) is a significant concern in the oil and gas industry. This paper presents several case studies of CUI, including instances of External Chloride Stress Corrosion Cracking (ECSCC). In our facilities, applying insulation material sprayed with a specific corrosion inhibitor to the internal surface is considered a temporary solution for equipment where CUI is a concern due to damaged coatings. In our previous study, this non-combustible corrosion inhibitor containing phosphate and nitrite showed effective corrosion inhibition in carbon steel even when rusted. However, we considered that an Active Path Corrosion can be occurred under loaded stress portions. To replicate chloride-concentrated environments under insulation, a 70-day immersion test was conducted using U-bend type test specimens of carbon steel in a NaCl solution with the inhibitor. The tested specimens with the inhibitor maintained a metallic appearance without stress corrosion cracking. However, crevice corrosion was observed. These results suggest that the corrosion inhibitor may have limited effectiveness in chloride-concentrated environments. We concluded that it is beneficial to perform cleaning before applying the insulation with corrosion inhibitor and to implement other permanent measures before chloride concentration significantly increases.

Several components in geothermal power plants need to be protected from the environment due to the corrosive nature of geothermal fluids used to generate the energy. Depending on the fluid properties for any location, the type of protection varies. In geothermal power plants, wear, erosion, corrosion, and scaling are all known problems1. These issues can lead to a variety of outcomes, ranging from decreased plant efficiency to upstream component failure. Failure of a component is thus a significant challenge in the geothermal industry, where materials need to operate in high temperature and high pressure environments. A major cost factor is also linked to the drilling of geothermal wells, where cost rises due to increased depth/distance of drilling, increased trip times, higher high temperature and high-pressure conditions which can lead to increased wear and corrosion of the materials. To address the issue, coatings can be considered to be a potential solution to extend the service life of downhole equipment.
