The Great Lakes Water Authority announced that it is currently increasing dosage of the anticorrosion additive orthophosphate, which it feeds into the water produced by its five water treatment plants in southeast Michigan.
In this “Never Again” article, Jon Cavallo explores whether the role of solvents and/or thinners is simply to control viscosity. As part of this review, an investigation of observed bridge coating failures near Panama City, Florida, USA, was conducted on several fronts.
Performance of a painting system depends heavily on surface preparation. The surface must be clean and free of any contamination, such as oil and grease, dust, moisture, or soluble salts, and a surface profile should provide sufficient conditions for adhesion. Such is the case with water ballast tanks, as it is not easy to inspect the area. Moreover, maintenance costs are high.
Maintaining exterior paint in industrial environments requires a strategic approach ranging from product selection to application. By using these tips and professional expertise, companies can offer solutions featuring exterior paints and coatings that last longer and look better.
An underground oil pipeline at a Spanish refinery was suffering from severe corrosion, and it would have incurred severe metal loss if left unchecked. Instead, a composite wrap solution allowed the customer to avoid a complete replacement.
Although the corrosion rate of bare steel tends to decrease with time in most cases, the difference in the corrosivity of different atmospheres for a particular alloy can be tremendous.
A research team from the University of Alberta has discovered what they believe is a groundbreaking material for high-temperature coatings. According to the researchers, it shows strong potential for applications such as hydrogen combustion engines.
Alternatives to nickel-based alloys can help the United States meet its clean energy goals, and scientists at the Argonne National Laboratory believe they are on a fast track to further discovery—including one new coating material with enhanced corrosion resistance.
Jeff Jirak, managing director of AkzoNobel’s global powder coatings business, shares details of the manufacturer’s development partnership with coatingAI. The program aims to assist contractors and installers with application processes while reducing their carbon footprint.
Many pipeline companies ignore the occurrence of external corrosion when cathodic protection (CP) is considered adequate. In these situations, understanding the failure mode of the coating and why CP cannot adequately protect the pipe under certain disbonded coating types is critical.
Paints and coatings manufacturer Sherwin-Williams recently announced top honors in its annual Impact Award program. This year, first place was awarded to a landmark infrastructure upgrade in Fargo, North Dakota, USA, which aims to boost wastewater treatment capacity.
The interiors of large pipelines carrying corrosive liquids may be lined with a suitable coating and protected with a strip-type galvanic anode material. If the pipe interior is bare, relatively large amounts of current may be needed.
AMPP’s SC 08—Metallic Material Selection and Testing, SC 05—Surface Preparation, and SC 26—Carbon Capture, Alternative Fuels, and Energy Storage are among the Standard Committee (SC) groups that have begun new projects in recent months.
After undergoing rigorous testing to ensure suitability for dry food contact, a breakthrough was achieved with the successful application of Belzona’s 5811 immersion-grade epoxy coating. This cutting-edge tank lining was recently installed at a flour mill in Belgium.
The most common alloys used for exposure at high temperatures are the iron/nickel/chromium alloys, often referred to as stainless steels (SS). The materials used may be cast or wrought.
