A neutralizer is a substance or material used in the neutralization of acidic water. It is a common designation for alkaline materials such as calcite (calcium carbonate) or magnesia (magnesium oxide) used in the neutralization of acid waters. Neutralizers help prevent: Acidic well water from… View Full Term

Preventing Corrosion with Thermal Insulating Coatings on...
For those with no real-world experience in oil & gas refining environments or with corrosion under insulation (CUI), the white paper, “Selection of Coating Systems for CUI Service” by Christian Zupicich and Michael MeLampy,...
By: Monica Chauviere | President, Monicorr, Inc.
New insulating coatings are gaining popularity due to their ability to reduce product vapor loss and volatile organic compounds, while eliminating CUI.
Advancements in nondestructive evaluation (NDE) technologies have enabled the process industry to carry out CUI inspection without removing insulation.

In petrochemical refineries, the majority of pipeline failures are due to three corrosion mechanisms. This article discusses how to survey to determine corrosion under insulation (CUI) prone equipment and plan corrosion control inspections.
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.

It is a myth that if the right coating is put on after excellent surface prep, everything will be fine, regardless of the insulation.
There is no such thing as a perfect coating. In this article we explore a common myth of corrosion under insulation.
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.

There is no standard method to prevent corrosion under insulation (CUI), only a series of best practices, which when followed properly along with the use of appropriate materials can mitigate the risk.
