... temperature and the presence or absence of insulation at the intended installation location. Consequently, it is essential to apply a coating system that offers reliable corrosion protection performance under various situation, including high temperatures, low temperatures, atmospheric exposure environments...

... ABSTRACT Corrosion under insulation (CUI) happens due to moisture egress and thermal cycling. Chemical inhibitors can be a relatively low-cost method to mitigate CUI. Inhibitors for CUI that are stable at temperatures below 175°C exist. However, many pipes have thermal cycling at temperatures...
