Corrosion Under Insulation (CUI) is one of the most critical issues facing the oil, gas, and petrochemical industries, costing the global economy an estimated $1 trillion annually. 40-60% of pipe maintenance costs result from CUI. Properties like the cell structure, water absorption, and soluble chloride levels of the insulation material directly impact the corrosion risk. Therefore, selecting appropriate insulation systems and meticulous engineering practices, considering not only the material but also water ingress scenarios, is vital for effectively managing CUI and extending equipment lifespan.
