An Introduction to the Root Causes of CUI with Monica Chauviere


Misconceptions abound regarding corrosion under insulation (CUI). From imperfect coatings and wet insulation dynamics, to design flaws that trap water, the proper...

All About Pitting Corrosion


Pitting corrosion, although relatively small in size, can result in catastrophic failures in a variety of structures. Its unpredictability and difficult detection make...

Understanding a New Trend: In Situ Cleaning and Coating


Every corrosion, abrasion, or erosion issue can present its own unique set of problems and associated solutions, each bearing its own merit. This is where in situ...

Corrosion Resistant Composite and Cured-in-Place Pipe


Corrosion happens in water, waste and industrial usage lines. Using a corrosion resistant cured-in-place pipe (CIPP) liner to repair the damage allows workers to repair...

4 Types of Tests that Measure the Strength of a Coating


Testing the mechanical properties (e.g., adhesive strength) of a coating is one of the best ways to ensure that the coating in question can handle the environmental and...

Concrete Flooring Moisture Issues


Addressing concrete floor moisture begins with proper design, curing and surface preparation. Testing for moisture content and identifying its source are very important...

Decommissioning Your Cathodic Protection Well


Decommissioning a deep anode well or ground bed simply by removing the surface hardware and walking away is often no longer acceptable. Learn the proper steps to take in...

Understanding Corrosion in Pumps and How to Deal With It


Even after taking all the precautionary measures, certain unexpected pump failures can still occur. Research studies say that corrosion is one of the main causes; but...

Blast Pressure: How to Get It Right


Finding the optimum blast pressure is a balancing act that entails taking into consideration the requirements of the job and the capabilities of the compressor, the...

Cathodic Protection of Earthed Tank Farms


Here we talk about the different cathodic protection system arrangements that are used for corrosion control of earthed tank farms, some of the problems that arise, and...

The Crystalline Structure of Metals


Materials are made up of a wide variety of atomic structures. However, metals in particular almost always have their atoms organized in a crystalline structure –...

Review of Solvent-Free Epoxy Protection for Secondary Containment Concrete


Liquid hazardous materials must be stored in such a way that if a spill or leak occurs, the material stays contained and does not contaminate the surrounding environment...

Cold Corrosion and a Systematic Approach to Preventing It


Systematic preventive maintenance and monitoring procedures can alleviate equipment damages due to cold corrosion in IC engines as well as boiler plants. Find out more...

Expanded Perlite Insulation: Why Hydrophobicity is Only Part of the Solution to Prevent CUI


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

Will using wet abrasive blasting instead of dry eliminate dust?


Firstly, before we answer this question it is important to clear up a common misconception. There is no such thing as a 100% dustless surface preparation method. (For...

What do I need to consider when it comes to applying high solids coatings?


High solids coatings can offer numerous advantages when compared to solvent-based coatings. Some of these advantages include better durability, faster drying times and...

How can you avoid flash rust during wet blasting?


Flash rust is defined as the corrosion that occurs on the surface of a metal shortly after any wet method of surface preparation. This type of rusting typically occurs...

How can I determine what blast pressure is best for my application?


The blast pressure directly determines the velocity of the blast media through the blasting nozzle, and therefore the impact force on the substrate.While there are a...

What is a plural component protective coating and what is it used for?


Plural component protective coatings, as the name suggests, are coatings that are made up of separate elements that are combined prior to application. High solid...
