How to Handle Corrosion on a Cold Box

Cold Boxes are essential to the air separation process. 

That is why you want to make sure that you are evaluating the corrosion on your cold box before issues arise. In this video, Brio Services’s own Danny and James sit down to discuss what sort of treatment needs to be done on a highly corroded cold box. They discuss scope of work for the painting contractor, essential tools & coating materials, and best approaches for this project. 

Here are the hightlights: 

  • The first objective of anyone who is looking at re-coating a cold box is to inventory the severity of the corrosion:
    • Identify the following: 
      • Flaking paint areas
      • Visible rust areas
      • Cold spots
    • Other items to consider:
      • The area around the cold box
        • Is the environment around the coldbox conducive to corrosion build-up (i.e. near seawater, other manufacturing facilities, etc.) ? 
  • After all the corrosion areas are identified, a plan of action must be created. 
    • Cold spots
      • Work needs to be performed when the cold box is shut-down so that the area under the ice can be coated properly.
    • Flaking paint
      • Clear flaking paint from the area before application of the new coating. Flaking paint can be removed through the washing process or sanded off. 
    • Visible rust
      • Treat rust with a prime layer of specific industrial coatings so that the corrosion is encapsulated. 
  • Give feedback to your painting contractors & ask questions
    • At Brio Services, our goal is not only to corrosion control your equipment but also to improve the aesthetics. We want to make sure that whoever we work with is happy and satisfied with project completion.
