Maximizing plant performance

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.  Learn more about how a versatile CUI maintenance solution can improve productivity all year round in our latest article, by completing the form.

Intertherm 751CSA

-196°C (-321°F) to 650°C (1202°F)

Renowned 'Cold Spray Aluminium' technology with excellent CUI and thermal cyclic resistance.

  • Excellent resistance to “thermal shock”  experienced during rapid temperature cycling
  • Can be applied at 200um (8 mils) in a single coat using standard application equipment
  • Suitable for application to steel substrates operating at temperatures up to 302°F (150°C)

Interbond 2340UPC

-196°F (-321°F) to 230°C (446°F)

Reduce the risk of early failure and maximize productivity vs traditional solutions.

  • Low temperature cure down to -5°C (23°F)
  • Excellent tolerance to over-application
  • Short minimum overcoating intervals
  • Suitable for application to steel substrates operating at temperatures up to 120°C (250°F)

Intertherm 2205

Up to 230°C (446°F)

No need for shutdowns - application directly to high temperature online equipment.

  • Hot application to live equipment up to 205ºC (401ºF)
  • Excellent adhesion to steel cleaned by hand or power tool (St2/SP2 preparation)
  • Cures ready to insulate after 10 minutes (when applied at temperatures above 100°C (212°F)

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.
