July 9 – Should You Worry about CUI on the Coke Drum Structure?


Evan Hyde Facilitator: Evan Hyde – REFCOMM®


Corrosion under insulation (CUI) is one of the best known and researched corrosion mechanisms in process industries. CUI is not often discussed in the context of the delayed coker specifically or especially around the drum structure equipment itself. The webinar will take the opportunity to explore how insulation on the inlet, outlet, and drum itself should be considered from a cyclic standpoint and not just from the design temperatures alone. The problems related to outside diameter corrosion can sneak up and bite you in a big way if you are not properly inspecting for it over the long term.
