Alumina-Forming Austenitic Alloys Resist High-Temperature Corrosion

A new class of high-temperature alumina-forming austenitic stainless steel alloys deliver both superior corrosion and creep resistance for many industrial environments.

IMPACT Breaks New Ground in the Study of Corrosion Management

NACE International has embarked on a new study, IMPACT, that not only addresses the economic effects of corrosion, but focuses on public safety, environmental concerns, management, and planning on a global basis.

Sensors Can Predict Corrosive Conditions in Military Aircraft

For the DoD’s fleet of aircraft, environmental exposure can cause corrosion damage that leads to degradation of the airframe structure, electrical wiring and interconnection system, and avionics. While nondestructive evaluation (NDE) techniques such as ultrasonic testing have been developed for aircraft inspection, the primary means used by military maintainers to assess an aircraft for corrosion is generally a schedule-based inspection of the airframe Many times corrosion damage can go undetected and untreated in locations that are difficult to access, which can intensify structural damage and cause safety issues. To address this, a self-contained multi-modal corrosion sensor system has been developed to measure, record, and analyze environmental and corrosivity parameters that affect corrosion susceptibility and corrosion rate of a material.

Wire/Strand Slippage—A Potential Failure Mode for Post-Tensioning Tendons

A forensic investigation of unbonded, post-tensioning tendons on a large structure revealed relatively advanced levels of strand corrosion within and inboard of the end anchors. Strand corrosion within anchors was so advanced that wires had disengaged from the wedges, resulting in slip, contraction, and consequent load reduction in the strand.

Correcting Concrete Corrosion

Corrosion of the reinforcing steel in concrete is a worldwide problem that causes a range of economic, aesthetic, and utilization issues. However, if corrosion effects are considered in the design phase and the right decisions are made prior to construction, buildings can be constructed to resist corrosion.

Evaluating Sensors to Monitor Steel Corrosion in Concrete Structures

Corrosion costs have compelled the Florida Department of Transportation (FDOT) Corrosion Research Laboratory (Gainesville, Florida) to investigate new technologies and methods that can assess concrete bridge structures for corrosion

Corrosion of Copper Alloys in Consumer Electronics Environments

Results of corrosion testing on eight alloys from five copper alloy families commonly used in the consumer electronics industry are presented. Short-term exposures were conducted in simulated consumer environments such as a salted carbonated cola beverage, artificial human perspiration, and phosphate-buffered saline.

Corrosion Risks and Mitigation Strategies for Offshore Wind Turbine Foundations

An increasing number of wind turbine structures have been installed, particularly on monopile foundations. Corrosion experiences and mitigation strategies reported by the offshore wind energy industry for these foundations are discussed.

NACE Technical Committees—Volunteering Has Its Rewards

Want to know how you can become more active in NACE? There are many opportunities for NACE members to volunteer, and the technical committees offer many benefits such as having an impact on industry standards, developing a network of peers, and enhancing your career.

IMPACT Study Benchmarks Corrosion Management Practices Across Industries

NACE International has embarked on a study—IMPACT—that goes beyond the economic effects of corrosion; it emphasizes how to integrate corrosion technology with organizational management systems to optimize corrosion decisions with respect to both cost savings and concern for safety and the environment.

Novel Technique Studies Water Pipe Corrosion Caused By Microbes

With adaptation, the authors say this system could be used to accurately replicate corrosion in soil with the introduction of nutrients to match the soil environment in question and cultured biofilms found along buried pipelines.

Gas Plant Uses Carbon Fiber-Reinforced Polymer Wrap to Strengthen Concrete Columns

Pipe wrapping turned out to be a simple and low-cost method for strengthening concrete columns during the construction of a new natural gas plant in Colorado.

Essential Elements of a Successful Corrosion Management Program

A materials specialist at Bechtel explains why maintaining an effective corrosion management program is essential for achieving high reliability at any oil and gas production or refining facility.

Preventing Releases in Underground Storage Tanks

Underground storage tank (UST) owners and operators must follow correct filling practices and protect their USTs from spills, overfills, and corrosion. Additionally, owners and operators must report the existence of new UST systems, suspected releases, UST system closures, and keep records of operation and maintenance.

Robotic Crawlers Inspect Unpiggable Pipelines

Advanced robotic inline inspection (ILI) crawlers have now been successfully used to inspect two previously unaccessible North American pipelines on the Trans-Alaska Pipeline System (TAPS) and the Transco Pipeline.
