In their 2024 AMPP paper, these authors proposed a technique for early-stage pitting detection through machine learning. Pitting is a localized form of corrosion that can cause cavities and structural failure in metallic materials, and it can be challenging to detect and prevent.
According to Utah State’s primary researcher involved in the study, one of the most important indicators for identifying failing pipelines is water main break rates. Pipe performance continues to be impacted by soil corrosivity, and the replacement of asbestos cement and cast-iron pipe is creating a shift in predominant pipe materials.
After finding a water leak from its holding tank, the owner/operator of a town water tower reached out to Total Access Solutions Co. (TASC) to request an inspection. One TASC got on site, investigators were able to deduce more information about the potential cause(s) of the premature failure.
This two-part article reviews the corrosion risk assessment, structural considerations, and engineering solutions for the steel-reinforced structural elements of an aging concrete building. This building had exhibited accelerated corrosion in corrosive environments.
When compared with metals, polymeric materials tend to be more resistant to chloride ions and hydrochloric acid. However, polymeric materials are generally weaker and softer; less resistant to concentrated sulfuric and oxidizing acids and solvents; and subject to temperature limitations.
Based largely on its self-healing ability under corrosion attack, scientists believe they have found an anti-corrosion polymer that “represents a promising thermoplastic alternative to the thermosetting resins commonly used for metallic corrosion protection.
In a newly released investigative report, the Transportation Safety Board of Canada says external corrosion led to a natural gas pipeline rupture near Fox Creek, Alberta, which caused an explosion and fire near a small community.
The Texas Department of Transportation issued a three-year grant to evaluate deteriorating and aging highway bridges. The approach includes non-destructive evaluation, on-site load testing, and computer simulations to help engineers determine the current bridge conditions.
In this case study, significant corrosion was observed on lines supplying air handling units and swimming pools at a Dubai hotel. According to the client, the chilled water application system was installed three years prior and initially handled by a maintenance contractor before being handed over to the asset owner.
In a recent National Construction Safety Team (NCST) Advisory Committee meeting, National Institute of Standards and Technology (NIST) investigators shared details of their investigation into the partial collapse of the Champlain Towers South building in Surfside, Florida, USA.
To protect steel surfaces from corrosive forces, researchers at Sandia National Laboratories tested several nickel and nickel-based alloy cold spray coatings to determine their ability to offer corrosion protection for 304L stainless steel in chloride-rich environments.
U.S. National Transportation Safety Board (NTSB) investigators believe a deadly natural-gas pipeline explosion in rural Arizona resulted from gaps in protective tape wrapping. This led to water leakage and corrosion and cracks along a seam weld.
Michael Beamish, vice president and general manager at DeFelsko Corp., shares feedback he’s heard from coatings inspectors about their challenges in the field. In 2023, many of these needs revolve around increasing speed and reporting efficiency.
With the Northern Hemisphere’s 2023 hurricane season in full swing and nearing its annual peak, emerging technologies and artificial intelligence are among new tools offering hope for superior pipeline protection against mighty storms.
Quantifying microorganisms associated with microbiologically influenced corrosion (MIC) can provide insight into a system’s corrosion risk, as well as the efficacy of its management programs. This article features related insight from LuminUltra, which was a winner in the 2023 Materials Performance (MP) Corrosion Innovation of the Year Awards.
