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).

Underdeposit Corrosion in a Subsea Water Injection Pipeline

Underdeposit corrosion (UDC), a general term that refers to localized corrosion that develops beneath or around deposits on a metal surface, is a phenomenon that leads to pipeline failures and is one of the most damaging forms of corrosion for oil and gas pipelines. It can occur in subsea water injection pipelines, well-fluid pipelines, and large-diameter transmission lines.

Novel Design, Coatings System Resists Weathering at Tropical Complex

The combination of a unique architectural design finished with fluoropolymer coil coatings is geared to provide seacoast corrosion protection for upscale condominiums in Florida. The unique climate concerns to the region prompted an innovative concept from globally renowned architecture company Bjarke Ingels Group (Brooklyn, New York, USA).

Corrosion Basics—Corrosion Damage in Reinforced Concrete

The main causes of corrosion of steel in concrete are chloride attack and carbonation. These two mechanisms are unusual in that they do not attack the integrity of the concrete. Instead, aggressive chemical species pass through the pores in the concrete and attack the steel. This is unlike normal deterioration processes resulting from chemical attack on concrete.

Iridium—The Ultimate in Corrosion Resistance

Iridium is a hard, brittle member of the so-called platinum group of metals in the periodic table. As an alloying element, it increases the corrosion resistance of titanium and palladium. We know that corrosion is a reaction between a material and its environment, so why not have a look at the most corrosion resistant metal in the periodic table.

Advanced Corrosion, Rust Drive Brake Pad Failures

A new study from the Global Brake Safety Council suggests the use of substandard materials and processes in automobile brake pads could be leading to accelerated failure modes. The council was formed in 2014 to advocate and raise awareness for high standards in brake safety while ensuring responsible manufacturing in the automotive industry.

Corrosion Basics—Types of Corrosive Atmospheres

Although atmospheres can be classified into four basic types, most of them are mixed and present no clear lines of demarcation. Furthermore, the type of atmosphere may vary with the wind pattern, particularly where corrosive pollutants are concerned.

Corrosion Basics—Corrosion Surveys

Two of the most fundamental and informative field measurements are soil resistivity surveys and pipe-to-soil potential surveys.

Field Joint Coatings

Engineering and selecting the most adequate and appropriate pipeline coating depends on a multitude of factors. Careful analysis of several critical factors must be considered, such as the pipe diameter, the service pressures or operating temperatures of the transport materials, the soil conditions if installing a landline, construction techniques for installation, cathodic protection (CP), and whether impressed current CP or sacrificial CP will be used.

Researchers Suggest New Method to Create Corrosion-Resistant Alloys

A new study suggests that a better protective oxide scale can be achieved in high-temperature Al alloys by controlling the size distribution of reactive element particles. These types of alloys are prevalent in many industrial sectors and applications.

2018 Deadline Nears for New U.S. Underground Storage Tank Rules

The third and final deadline for underground storage tank owners and operators to meet new federal requirements from the U.S. Environmental Protection Agency for spill, overfill, and corrosion protection is October 13, 2018.

Corrosion-Inhibiting Primer Helps Restore Historic Croatian Monument

A surface-applied corrosion inhibitor, designed to migrate through dense concrete structures and seek out the steel reinforcement bars in concrete, helped stop further corrosion on this iconic Croatian structure.

Corrosion Basics—Water Constituents

In water, the concentrations of various substances in dissolved, colloidal, or suspended form are typically low, but may vary considerably depending on the components and usage. For example, hardness values of up to 400 parts per million of calcium carbonate is sometimes tolerated in public supplies of potable water, whereas 1 ppm of dissolved iron would be unacceptable.
