According to AGM, the Genable CX primer operates as a high-performance hybrid system that relies on graphene and aluminum chemistries to provide anticorrosion protection for offshore, marine, and other harsh environments.
In deep-water applications in the Gulf of Mexico, vibration-induced fatigue issues often arise due to wave-induced motion, vessel-induced motion, vortex-induced vibration, and/or flow-induced vibration.
There is growing concern that prestressing steel strands within post-tensioned tendons could experience hydrogen embrittlement. One proposed source of hydrogen is galvanic coupling that may exist between the galvanized steel duct and the steel strands.
Carbon fiber strands have a tensile strength comparable to steel, but they resist corrosion and require less maintenance over time. Longer service life is the major benefit, according to Michigan Department of Transportation officials.
Stainless steels differ in terms of corrosion resistance, and the need to determine their corrosion resistance is essential. A standard test method that is reliable, reproducible, and quick is crucial.
This article focuses on several coating failures on the external surfaces of a carbon steel cargo container. Because this container was newly constructed, a fresh painting system was applied and touched up or spot repaired in some locations.
This article presents two case studies of failed pipe fittings. A perforated tee and a pipe nipple retrieved from onshore shale production systems were analyzed to determine the mechanism(s) contributing to their corrosion and subsequent failure.
Reviewing data from case studies shows the effectiveness of duplex zinc coatings at lessening the effects of corrosion on steel used in commercial fishing boats. These mitigating effects are evident internally and externally, and above and below the waterline.
In this newly released AMPP webcast, inspection and policy experts explore the basics of the building inspection process; strategies to ensure buildings are protected; and important resources and tools. They also respond to viewer questions.
The scientists emphasize that improving the quality of concrete used in creating marine structures can be accomplished by making it less permeable and increasing the clear cover. When these steps are taken, the time to corrosion is much longer.
Officials from some states told the U.S. Government Accountability Office that they use sealant on bridge decks to prevent corrosion. However, officials from another said they do not, because they do not know how effective it is.
When designing a heat exchanger system, engineers must consider ways to control and mitigate the many different kinds of fouling. These control plans must be reviewed on a case-by-case basis for each unique environment.
Laboratory testing using biofilms can provide a reliable means to evaluate the potential for microbiologically influenced corrosion (MIC), and subsequently, to assess the effectiveness of biocides to inhibit biofilm growth and mitigate MIC during hydrotesting and wet parking.
River Scour Monitoring (RSM) systems, through the use of temperature sensing, have proven effective in detecting exposed pipe and the degree of pipeline scour. Identifying scour early on is key because once a pipeline is uncovered, it can be damaged in multiple ways. To avoid pipeline operator liability, and keep people, the environment, and related resources safe, it is important to follow applicable regulations and codes.
Led by Dr. Mehrooz Zamanzadeh, technical director and principal investigator at Matergenics, this roundtable discussion explores the need to conduct corrosion risk assessments of infrastructure after exposure to wildfires.
