How liquid coatings curb corrosion under insulation (CUI) in LNG service
High performance solutions deliver longer maintenance-free operations
The hidden dangers of corrosion under insulation (CUI) span the oil and gas industry from upstream operations to midstream infrastructure to downstream applications, including the production of liquified natural gas (LNG).
CUI is a severe form of localized corrosion that occurs when water, inorganic salts and other contaminants become trapped beneath insulation covering pipes, valves, tanks and other assets, leading to the formation of corrosion cells that are hidden from view and can spread unnoticed.
In LNG operations, cold/cryogenic temperatures can contribute to increased CUI risks. Moisture from condensation can be especially prevalent under insulation in cryogenic LNG operations due to the extreme temperature differentials with ambient air.
Newer liquid coatings offer facilities the opportunity to mitigate corrosion far longer than previous options, helping owners extend coating maintenance schedules, reduce operational costs and enhance safety.
