External Corrosion Sparked Canadian Gas Pipeline Rupture, Fire

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.

Texas Awards Grant to Evaluate Aging Highway Bridges

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.

Never Again: Dealing With the CUI Phenomenon

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.

NIST Updates Investigation of Champlain Towers Collapse

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.

Can Cold Spray Coatings Protect Steel from Corrosive Chlorides?

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.

How Stress Corrosion Cracking Led to Arizona Pipeline Blast

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.

Interview: How Coatings Inspection Needs Are Evolving

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.

Advances in Protecting Pipelines from Hurricane Damage

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.

Using Advanced Microbial Monitoring to Quantify Corrosion Risks

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.

Novel Evaluation of a Marine Coating Failure

There are many methods to evaluate the corrosion of substrates and breakdown of protective coatings that are subject to wet-dry cycling in natural and accelerated environments. This article explores ways to predict failures without having to artificially harshen those conditions.

Piping Failure: Petroleum Refinery Fire Water Line

In this case study, a piping failure during fire water service operation was investigated using metallographic techniques. According to the author, the use of metallurgical investigations during inspection programs for petroleum and petrochemical plants can help to discover the root causes of corrosion.

University Researchers to Combat Corrosion with Microorganisms

A team of researchers from Texas A&M University, Tufts University, and the University of Oklahoma is working collaboratively on a project focused on combating microbiologically induced corrosion, and especially corrosion affecting U.S. Air Force fuel tanks.

How to Investigate Premature Coating Failures When They Occur

While time and money are always lost when faced with a premature coatings or linings failure, the biggest loss is often that of reputation. Mike O’Brien of MARK 10 Research Group, Inc., made that clear during an AMPP 2023 forum presentation.

Concrete Treatment Stops Microbially-Induced Corrosion in Wastewater

The Penetron Group has developed an antimicrobial concrete admixture to provide permanent protection for the lift station’s wet well structures from microbially-induced corrosion (MIC).

U.S. Navy Patents Fiberoptic System to Detect Corrosion

The U.S. Naval Surface Warfare Center patented its process for applying a “smart” fiberoptic system between a metal surface and its protective coating, which they believe can detect the beginnings of corrosion at the microscopic level.
