U.S. Study Finds Millions at Risk of High Lead from Corrosive Water

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.

High Pressure Key to More Advanced Metal Alloys

A new study suggests that high pressure could be the key to developing advanced metal mixtures that are lighter, stronger, and more resistant to heat and corrosion than conventional alloys.

Detecting Corrosive Sulfides Challenges U.S. Shale Operators

Many modern tests focused on the detection of sulfate-reducing bacteria as corrosive agents in metal oil and gas pipelines could be missing a separate bacterial family also responsible for corrosion.

Degradation of a Thrust Bearing in a Lift Pump on an Electromotor Offshore Platform

This article discusses the causes of bearing failure, its avoidance, and a repair method for damaged thrust bearings.

Fluoride Corrosivity on Mild Steel in Cooling Systems

Empirical data were used to construct statistically sound models pertinent to fluoride-containing brackish water, and the models were verified against field corrosion coupon data.
