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.
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.
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.
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.
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).
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.
Denver Water is receiving $76 million in funding from the U.S. Bipartisan Infrastructure Law to accelerate its lead-service line replacement plan, which was recently approved and found to be effective by the Environmental Protection Agency.
Based on empirical and theoretical research validated by field data, Minnesota Department of Transportation (MnDOT) researchers developed a guidance tool to predict rebar reinforcement section loss. This should help MnDOT manage its bridge inventory and inform bridge maintenance and replacement decisions.
The U.S. Chemical Safety and Hazard Investigation Board released its findings regarding a massive fire and explosions at the Philadelphia Energy Solutions refinery in 2019. The incident occurred when a corroded pipe elbow ruptured, releasing process fluid into the hydrofluoric acid alkylation unit.
Knowing the corrosion severity of a particular environment is important when designing and maintaining infrastructure—and even more so in coastal environments. Certain factors can cause corrosion rates to vary significantly. This study aims to provide answers.
Hydraulic, electrical, and structural components of vehicles can be vulnerable to corrosion damage caused by deicers. To that end, a Scandinavian study found that cars driven on salt-free roads were 50% less vulnerable to cosmetic corrosion than cars exposed to road salt.
The Office of Rail and Road, the economic and safety regulator of Britain’s railway, made a series of recommendations based on a review of how the rail industry responded to a range of potential safety issues, including cracking.
Winning innovations must show potential for a positive impact in corrosion control. Innovations can be related to coatings and linings, materials, design, equipment, testing, monitoring, modeling/risk assessment, cathodic protection, chemical treatment, or beyond.
The Pennsylvania Department of Transportation released an inspection report completed on the Fern Hollow Bridge four months before its collapse, which appeared to show major structural decay. Despite findings from the fall 2021 inspection, no immediate repairs were ordered.
According to a study from the U.S. Government Accountability Office, a more robust oversight process is needed to ensure the integrity of approximately 8,600 miles of active offshore oil and gas pipelines in the Gulf of Mexico. New proposed rules are expected by late 2022.
