Investigators with the U.S. Chemical Safety Board say a June 2019 explosion and fire at the Philadelphia Energy Solutions (PES) refinery in Philadelphia, Pennsylvania, USA, occurred due to a corroded pipe elbow in the refinery’s alkylation unit.
The city of Newark, New Jersey, USA, is introducing a new corrosion control treatment program and working to replace lead service lines on private property after tests have repeatedly showed elevated lead levels in drinking water.
In their final report, U.S. investigators say thermal fatigue in a heat exchanger likely caused a major hydrocarbons release in June 2016. This resulted in a series of fires and explosions at the Enterprise Products gas plant in Pascagoula, Mississippi.
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.
New Zealand’s Transport Accident Investigation Commission published its final report on a fatal accident involving the massive Emerald Princess cruise vessel, in which a nitrogen cylinder burst and fatally injured a nearby crew member.
The City of San Francisco needed to determine the condition of offshore pipelines and their support structures and whether they were fit to continue operating, needed repairs or replacements, or required coating or lining repair.
According to U.S. researchers, a localized form of nanoscale corrosion appears responsible for unpredictably decreasing the working life of steel pipes used frequently in the oil and gas industry.
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.
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.
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.
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.
A recent study from European university scientists suggests that samples of reinforced concrete need to be larger to ensure accuracy in corrosion detection.
An engineering study reports significant corrosion, due to poor coating selection and application, that led to structural damage in many locations at a major college football stadium in Florida.
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.
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.
