Corrosion Under Insulation (CUI) Treatment

BIEWU International offers specialized Corrosion Under Insulation (CUI) treatment and prevention solutions utilizing Cortec VpCI® (Vapor Phase Corrosion Inhibitor) technology. These systems are engineered to protect insulated piping, vessels, and process equipment from corrosion damage, extending service life and reducing maintenance costs. CUI is among the most persistent challenges in the oil, gas, and process industries, often developing unnoticed beneath insulation due to trapped moisture, temperature variations, and environmental exposure. BIEWU’s advanced VpCI® solutions deliver both active and vapor-phase corrosion protection, reaching concealed areas beneath insulation where conventional coatings cannot — ensuring comprehensive and long-lasting defense for critical assets.
