University researchers issued findings on policy problems that led to the Flint water crisis and recommended legal changes to mitigate future concerns, including better communication on issues such as corrosion controls.
A recent study from European university scientists suggests that samples of reinforced concrete need to be larger to ensure accuracy in corrosion detection.
Industry panelists share their predictions on where the corrosion industry is going in the next 25 years and beyond by predicting the corrosion control developments of the future. For Part 2 of this series, the featured panelist is Fred Goodwin, head of BASF Construction Chemicals Global Corrosion Competency Center.
The polymer, which might someday be used as construction or repair material or for protective coatings, continuously converts the greenhouse gas into a carbon-based material that reinforces itself, according to the researchers. This “self-healing material,” designed to mimic the absorption properties of green plants, has potential applications in a variety of construction and protective coatings projects.
The Air Force Research Laboratory says it is developing a new environmental sensing platform and testing chamber apparatus to enable superior management of aircraft corrosion. Researchers are currently testing both devices, which they believe could help preemptively predict corrosive environmental conditions before they can cause damage to military assets.
In the latest round of testing, investigators found that two tanks at the decommissioned Hanford nuclear production complex in Washington had spots showing significant thinning in a ring around the shell’s wall.
Underdeposit corrosion (UDC), a general term that refers to localized corrosion that develops beneath or around deposits on a metal surface, is a phenomenon that leads to pipeline failures and is one of the most damaging forms of corrosion for oil and gas pipelines. It can occur in subsea water injection pipelines, well-fluid pipelines, and large-diameter transmission lines.
A new study from the Global Brake Safety Council suggests the use of substandard materials and processes in automobile brake pads could be leading to accelerated failure modes. The council was formed in 2014 to advocate and raise awareness for high standards in brake safety while ensuring responsible manufacturing in the automotive industry.
A new study suggests that a better protective oxide scale can be achieved in high-temperature Al alloys by controlling the size distribution of reactive element particles. These types of alloys are prevalent in many industrial sectors and applications.
Corrugated iron has been and continues to be an invaluable building material that deserves to be taken seriously. It shows that steel can be simply and cheaply formed to a useful shape, protected from corrosion by a range of coatings, and made accessible to citizens in all corners of the globe.
The hydrophobic WR-Tech additive leads to stone wool, mandrel-wound pipe sections with significantly less water absorption relative to industry standards; faster drying rates; and durability over a wide range of potential CUI temperatures.
An investigative report into the 2015 blowout of a natural gas well near Los Angeles, California, USA, cited corroded pipe casings, safety failures by a utility, and inadequate regulations as incident causes.
As steam is produced in a boiler, the impurities left in the feedwater concentrate and precipitate out of the solution and onto the internal surfaces of the boiler, causing fouling. This reduces both the water flow and the heat transfer, decreasing the efficiency and power of the boiler. Such fouling can accelerate corrosion of the boiler, decreasing its life.
Researchers with the Minnesota Department of Transportation and the University of Minnesota have successfully tested a new, cost-effective method for repairing damaged bridge girders that they believe can restore them to their original shear strength or even make them stronger.
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.
