Electrode potential for any given electrode is the voltage or potential difference of a cell assembled from a standard hydrogen electrode and the given electrode with the potential that is being defined. It is the resultant potential difference between a point on the electrode surface and the point… View Full Term

Advancements in nondestructive evaluation (NDE) technologies have enabled the process industry to carry out CUI inspection without removing insulation.
By: Arun K. Soman, ME | Deputy Manager Inspection Advisory, Bharat Petroleum Corporation Ltd
Corrosion Under Insulation (CUI) is the root cause of many of the global petrochemical industry’s most serious problems including forced shutdowns, lost production, early repair and replacement, as well as safety and...

Misconceptions abound regarding corrosion under insulation (CUI). From imperfect coatings and wet insulation dynamics, to design flaws that trap water, the proper management of CUI requires a clear understanding of common thermal and mechanical issues.
By: Monica Chauviere | President, Monicorr, Inc.
With CUI, it's best to think about long-term solutions and minimizing future failures. This takes an effort at all phases of the life cycle, but it starts in the engineering phase.

This article, brought to you by David Shong and Jack Bittner, highlights the limitations of a hydrophobic-only approach to prevent corrosion under insulation.

They say that April showers bring May flowers, but this is not the case in the Seattle area where I live. April showers bring May, June and July showers, and occasional sun breaks three days in August. However, my role in...
It is a myth that if the right coating is put on after excellent surface prep, everything will be fine, regardless of the insulation.
If the jacketing on the insulation is not damaged and nasty-looking for hundreds of feet of piping there is not likely CUI on the steel. Wrong!
There is no such thing as a perfect coating. In this article we explore a common myth of corrosion under insulation.
Corrosion under insulation (CUI) causes many safety hazards in industrial facilities, many of which are prevented by using Mascoat's insulating coatings.In our last Quarterly Newsletter, we described multiple safety hazards...

By: Will Conner
To implement an effective strategy to prevent CUI, engineers, specifiers and facility operators need to consider the elements of an entire insulation system, from the material (rigid and non-rigid), to the jacketing, to the system specifications.
