A new underground radar technology system developed at Louisiana Tech University is helping a local city spot damage to infrastructure that had gone undetected since Hurricane Katrina.
Learn more about corrosion of stainless steel (SS) in this new Materials Performance quarterly special feature, “The Science Behind It.” Read the MP article about the root cause of a Type 316L SS closed drain line failure, then explore the science behind the corrosion problem, which is presented in several related CORROSION articles listed at the end of the article.
In a new report on corrosion inside underground storage tanks storing diesel fuel, the U.S. Environmental Protection Agency found moderate or severe corrosion could affect metal components inside both steel and fiberglass tank systems.
A new U.S. Geological Survey assessment of more than 20,000 wells nationwide showed that untreated groundwater in 25 states and the District of Columbia was classified as potentially corrosive, thus creating a high risk for lead leaching in homes.
New x-ray diffraction technologies are enabling corrosion analysis to be carried out much more quickly and thoroughly by using a portable unit in the field.
The new containment structure, moved into position in November 2016, includes a ventilation system that developers say will help ensure there is no need to replace the coating used to control corrosion.
Reinforced concrete samples with an organic corrosion-inhibiting admixture were exposed in a road salt environment in the Swiss Alps and periodically inspected over 18 years using a number of test methods.
The U.S. congressional committee investigating the water crisis in Flint, Michigan issued final letters citing failures at all levels of government, including problems at both the Michigan Department of Environmental Quality and the U.S. Environmental Protection Agency.
Led by university researchers, the findings of this new study support the understanding that lead leached into the pipes system in Flint, Michigan, because the water wasn’t treated to prevent corrosion.
Researchers with the Southwest Research Institute conducted experiments to evaluate the presence of microbiologically influenced corrosion under high and low relative humidity conditions when storing spent nuclear fuel in dry storage systems.
Divers conducting inspections of the Mickler-O’Connell Bridge detected heavy corrosion of the steel H-piles. Researchers suspect microbiologically influenced corrosion caused localized degradation.
Independent investigators found extensive corrosion on the well casing that broke open at Southern California Gas Co.'s Aliso Canyon gas storage facility in October 2015. In the aftermath, engineering consultancy Blade Energy Partners was granted authority by the California Public Utilities Commission (CPUC) to conduct a root cause analysis of the metallurgical and fractographic aspects of the gas leak.
A recent study from European university scientists suggests that samples of reinforced concrete need to be larger to ensure accuracy in corrosion detection.
Funded by the European Commission, this new project involves the design of a portable, three-dimensional ultrasonic scanner for the nondestructive testing and evaluation of concrete in bridges and other building structures.
The researchers conclude that the novel phosphonate chemistry is useful in ultrahigh geothermal applications. Its high tolerance to calcium, biodegradability, thermal stability, and good performance against calcium carbonate scaling prove valuable in many environments.
