Remote Imaging System to Spot Bridge Corrosion from Distance

Scientists are developing a new technology capable of detecting the level of rust on metal structures, such as bridges, from up to 100 m (328 ft) away. The project could save millions in surveying costs and remove the need for potentially dangerous inspections.

Niagara Falls Revamps Key Sewer Line with Liner Piping

What was first thought to be an infiltration problem evolved to include serious sewer structural and longevity concerns, and liner piping provided a potential solution.

Controlling Cavitation Damage in Pumps on Oil Offshore Platforms

This article explores possible remedies to cavitation, including finishing the surfaces of pump components with a hydrophobic composite coating with a smooth and glassy surface.

Leaking Seawater Tanks Repaired with New, Fast-Curing Material

When a vertical seawater tank sprang a leak at a coastal hydrocarbon storage tank farm in Italy, the tight time window for repair meant that only solutions with very short cure times were an option.

NACE Specific Technology Group Provides Railcar Industry Standards

Specific Technology Group (STG) 43, “Transportation, Land,” promotes the development of techniques to extend the life of land transportation equipment. The committee primarily focuses on writing standards and reports on industry best practices for coating application and corrosion control in and on railcars.

Selecting Stainless Steels for Seawater Pumps

Pumps are routinely used to handle seawater. With the increasing demands for low maintenance and reliable operation, it is important that suitable corrosion-resistant materials are selected for pumps used in seawater.

Key Indicators Can Reveal Signs of Concrete Parking Structure Corrosion

Experienced concrete maintenance and restoration specialists explain the unique challenges in protecting parking structures from a constant onslaught of environmental stressors and wear and tear, along with examples of successful repair techniques.

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.

Researchers Examine Corrosion of Lead Water Pipes in Aftermath of Flint

Even in the absence of funding for lead corrosion research, a team of scientists at the University of Virginia is pressing forward with a new project aimed at solving problems associated with leaching lead from water pipes.

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.

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.

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.

Scientists Add Biofilm to Protect Mortar from Moisture

Knowing that moisture can destroy mortar over time, a team of Technical University of Munich scientists developed a new process to limit water uptake by adding a biofilm while mixing the material.

Unmanned Aircraft Collect Cathodic Protection Readings on Remote Pipelines

Unmanned aerial vehicles (UAVs), are being utilized more and more in various industries to safely and efficiently inspect critical assets and infrastructure that would otherwise be difficult to access.

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.
