AkzoNobel's CUI & Cyclic Temperature maintenance solutions for downstream oil & gas

High Temperature Maintenance Range

Damage caused by Corrosion Under Insulation (CUI) and cyclic high temperatures is a common and ongoing threat to asset integrity in Oil & Gas facilities. That’s why our maintenance coatings are designed to provide reliable long-term resistance against these challenging conditions, as part of ongoing maintenance operations.

Achieve confidence in the safety of your asset
Reduce downtime through efficient application
Pre-empt the leading cause of asset corrosion

The high temperature maintenance range is made up of three specialist coatings designed to reduce designed to improve productivity and reduce the cost of high temperature maintenance.

Versatile CUI Maintenance?

Maintenance is an ongoing challenge all year round, and solutions need to be resilient to varying atmospheric conditions. Typically, traditional epoxy phenolic coatings for CUI service will not cure below 10ºC (50ºF) which can cause issues in the winter months, reducing productivity. Traditional epoxy phenolic coatings also show low tolerance to over-application, which is a particular challenge in maintenance as the variation of profile on pitted steel leads to areas of high DFT due to over-application. This stresses the coating and can cause cracking during high temperature service.
