An Environmentally Friendly Polyester Coil Coating Primer

A primer with ideal corrosion resistance and mechanical properties was developed by using waterborne saturated polyester, waterborne crosslinking agents, and Cr-Pb-free pigments and fillers with low-VOC content.

New Self-Powered Sensor Could Monitor Concrete Corrosion

Researchers and technology specialists in Denmark are working to develop a self-powered corrosion sensor to install inside steel-reinforced concrete structures, such as bridges.

General Motors Boosts Corrosion Prevention at New Assembly Plant

The $1.4-billion plant expansion in Arlington, Texas, USA, includes new robotics procedures and superior coating technologies, which are designed to enhance the corrosion resistance of automobiles.

Researchers Propose Less Corrosive Alternative to Road Salt

With the winter season underway in the Northern Hemisphere, a university research team is developing a more sustainable deicing solution for road infrastructure using grape skins and other agricultural waste.

Stress Cracking of Duplex Stainless Steel in Refining

The nature of duplex stainless steels (SS) makes them susceptible to failures observed in both austenitic and ferritic SS. Improper fabrication techniques lead to deleterious sigma and alpha prime phases, causing brittle failure.

Investigators: Corroded Pipe Led to U.S. Refinery Explosion, Fire

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.

Research Team Examines Pipeline Failure Prediction Models

In a new study, researchers at Concordia University and the Hong Kong Polytechnic University examine many methodologies currently used by industry and academics to predict pipeline failure—and their limitations. The researchers cite more than 10,000 pipeline failures in the United States alone as the motivation for their research, according to U.S. Department of Transportation data.

Pitting Test in Ammonia Flue Gas Desulfurization Slurry

Ammonia flue gas desulfurization (AFGD) has many advantages, but often it cannot work to its full capacity due to corrosion. In this study, seven widely used metal materials were placed in a custom-made device containing AFGD slurry to test for pitting corrosion.

New Metal Corrosion Sensor Designed for Printed Circuit Boards

Mitsubishi Electric has developed what it believes to be the world’s first compact metal corrosion sensor small enough to be mounted on printed circuit boards. The new sensor utilizes corrosion monitoring technology to detect the degree of corrosion of metal components caused by corrosive gases in the atmosphere.

Chemical Safety Board: Thermal Fatigue Led to Gas Plant Blast

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.

Novel Phosphonate Proves Useful in Geothermal Environments

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.

Robotics System Plugs Decommissioned Pipelines with Rigid Urethane Foam

A robotic spray-applied system utilizing rigid urethane foam could become an efficient solution to fill decommissioned energy pipelines, which would otherwise require cathodic protection (CP) or the application of a more burdensome filler, such as grout, to prevent soil corrosion.

U.S. Navy Develops ‘Topside Drone’ System for Vessel Inspections

The U.S. Navy has developed a new corrosion/anomaly detection sensor payload and processing scheme, outfitted to a commercial unmanned aerial vehicle, to help inspect for material defects, corrosion, warping, and more.

Internal Corrosion Protection Strategies for Aboveground Storage Tanks

In a CORROSION 2019 conference paper, the authors analyzed two case studies of corrosion-prone tanks using dissimilar metals and the challenges that arose in providing them with adequate cathodic protection (CP).

U.S. Navy Adopts Composite-Patch Repair Method for Aluminum

Engineers at the U.S. Naval Surface Warfare Center are now utilizing a new composite-patch repair method for incidents involving stress corrosion cracking on aluminum substrates.
