New Safe Containment Project Cuts Corrosion Risk at Chernobyl

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.

U.S. House Panel Concludes State, Federal Failures behind Flint

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.

Internal Corrosion Failures: Are We Learning from the Past?

Although methods for managing internal corrosion are well established, many pipelines operators experience repeated internal corrosion incidents, suggesting opportunities likely exist for continuous improvement.

Test Protocol Evaluates Concrete Repair with Sacrificial Anodes

One of the most common drivers of concrete repairs is corrosion of the concrete’s steel reinforcement, often caused by chloride ions in the environment entering the concrete and eventually reaching the embedded steel.

Innovative Polymeric Solution for Flanged Pipework Protection

Flanged pipework can be isolated from corrosive environments by using a flexible, liquid-applied elastomeric material that can be peeled off for inspection and then resealed.

Evaluation and Repair of a Liquid Sulfur Holding Tank

This case study presents the results of evaluations and repairs made to a sulfur tank at a gas plant in central Alberta, Canada. The repairs exceeded the owner’s expectations for performance and have not required any subsequent concrete repairs of significance.

Cold-Bonding Polymeric Technique Helps Restore U.K. Trains

A U.K. group specializing in train restoration identified polymeric cold-bonding as a superior solution to welding to help fix recurring problems with metal corrosion in diesel tanks.

University Team Develops Faster Route to Corrosion Detection in Metals

Researchers at the University of Virginia are seeking to modify the traditional cyclic corrosion test chamber by adding ozone to the mix and greatly accelerating the process.

Corrosion Behavior of UNS S31083 Duplex SS in China’s Yardang Soil

Due to the high carbon dioxide (CO2) and chloride content in natural gas produced by a gas field in Western China, a high-performance duplex stainless steel was chosen for gas gathering and transmission piping in this area.

Researchers Use Underground Radar to Detect Post-Storm Infrastructure Damage

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.

UAVs Capable of Inspecting Ship Tanks for Signs of Corrosion

By using UAV technology, survey times and staging costs associated with visual condition checks of remote structural components in ship tanks can be significantly reduced.

The Science Behind It: Localized Corrosion Failure of Type 316L Stainless Steel Drain Pipeline

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.

EPA Finds Moderate or Severe Corrosion in Most Underground Diesel Tanks

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.

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.

Results Posted for NACE International’s 2016 Annual Corrosion Career Survey

Average annual salaries in 2016 are reported for corrosion professionals in the United States, Canada, United Kingdom, and Europe. A slight gain was seen for the United States and United Kingdom, while a larger increase was recorded in Canada.
