Corrosion Management and Associated Implementation Issues

Any corrosion management implementation process should comprise three phases: pre-implementation, implementation, and post-implementation. Any shortcomings will adversely affect the outcome, effectiveness, and quality of the process. This article discusses corrosion management implementation issues and shortcomings that were observed during various campaigns or audits from around the world.

Lasers Could Replace Sanding, Blasting for U.S. Air Force

U.S. Airmen with the 60th Maintenance Squadron (MXS) at Travis Air Force Base in California, USA are one of two bases currently testing a pair of lasers as a new method of removing paint and corrosion on aerospace ground equipment. They say their traditional method involves the use of an orbital sander or blasting machine.

Corrosion Basics—Why Metals Corrode

Corrosion failures are often subtle and a result of invisible localized effects in the form of pits, intergranular corrosion, or attack within crevices.

The Humble Building Material that Shelters Millions Across the Globe

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.

Exploring Differences in Epoxy and Polyurethane Floor Coatings

Experts with a coatings specialist company explain the differences between floor coating systems based on polyurethanes and epoxies, and why the selection often depends on jobsite location. With each system offering differing properties suited to specialized uses, choosing the wrong solution can lead to costly repairs or even complete floor failure down the line.

Corrosion Basics—Safe Application of Protective Coatings

In every industrial environment, the safety factor is an important consideration. In some environments, including the application of protective coatings, it is of overriding importance. This article explores many of the safety factors that need to be considered.

Control of Environmental Degradation of Concrete Power Poles

Since significant funds are expended for replacement, an investigation was launched into the effects of mechanical activity and corrosion in the degradation of the concrete poles.

U.S. Scientists Develop New Oil-Resistant Filter Technology

Researchers at the U.S. Department of Energy’s Argonne National Laboratory are working on the development of a new oil-resistant filter technology to prolong the life of equipment in industries such as oil and gas. The new invention consists of a type of coating that produces thin films of oil-repelling molecules on the surface of filter membranes. According to the researchers, the metal oxide molecules grab onto any loose water atoms while resisting oil.

Corrosion Basics—Open Recirculated Cooling Water Systems

There are certain fundamental considerations that should be understood in relation to open recirculated systems, starting with the concept of cycles of concentration. If three cups of boiling water in a tea kettle were allowed to boil away to one cup, the residual cup would contain a three-fold concentration of soluble water salts, assuming that only steam was driven off.

Hot, Hot, Hot: Insulating the Inside of a Digester Complex

With the construction of a new digester complex for a Williston, North Dakota, USA wastewater treatment plant, it was imperative that the walls and pipes be properly insulated. Unfortunately, the insulation and pipe wrapping line item was accidentally missed on the bid.

Self-Healing Material Builds Itself from Carbon Exposure

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.

Roundtable on the Future of Corrosion Control: Part 2

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.

Tank Integrity Studied at Radioactive U.S. Waste Storage Site

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.

New Sensing, Simulation Tools Predict Military Aircraft Corrosion

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.

Cruise Ship Tests Surface Prep Kit to Boost Maintenance Efficiency

A novel corrosion control prevention kit utilizing shrouded surface preparation tools and demonstration videos is designed to improve the efficiency of in-house maintenance crews for maritime assets. Chris Patenaude, director of maritime and industrial sales at the company and also a NACE International-certified Coating Inspector Program (CIP) Level 3 Inspector, witnessed many common pitfalls firsthand in his prior role as global fleet superintendent for coatings and linings at cruise line operator Royal Caribbean International (Miami, Florida, USA).
