Concrete beams should be resistant against the influence of corrosive agents, environmental degradation, and mechanical forces. In this article, the effect of two different concrete mixing designs is investigated against the pole’s bend strength behavior.
This article presents an overview of corrosion-related issues that have been disclosed on post-tensioned bridges in both the United States and Europe.
The team utilized corrosion growth rate estimates collected from a dataset of operations from a North American pipeline operator’s integrity database, and developed machine learning algorithms to estimate risk.
Because refinery operations are so complex, and obtaining accurate asset integrity information has proven to be a challenge, a need exists for quantifying corrosion.
From a brief visit, it appears that along the Antarctic Peninsula, the low temperature and dryness retard corrosion in the face of corrosion-aggravating marine conditions.
Corrosion professionals in North America and Europe have experienced another year of continued growth in career opportunities and salary levels, according to the 2015 Corrosion Career Survey conducted by Materials Performance magazine.
An international oil and gas exploration and production company was looking to enhance oil recovery techniques in Oman. Internal coating of the pipelines provided corrosion protection, reduced friction, and improved flow efficiency when conveying corrosive water slurry, and offered adequate corrosion protection during subsequent transportation of recovered crude oil.
To successfully communicate the wide variety of corrosion-related issues affecting corrosion professionals today, MP is actively encouraging corrosion control professionals worldwide to submit technical articles to share their corrosion-related experiences with over 36,000 NACE International members around the globe.
Recent Materials Performance (MP) articles described the corrosion-related events associated with the new East Span of California’s San Francisco-Oakland Bay Bridge, which included a discussion on the shear key anchor rods that failed after tensioning, as well as the failure of a high-strength, galvanized tower anchor rod. To expand on these articles, MP asked roundtable panelists to comment on HE and its effect on the bridge’s high-strength steel rods, as well as other corrosion issues that could affect the bridge.
Cracks inside a de-ethanizer column were discovered during shut down.A high-velocity arc spray (HVAS) thermal spray method and high-performance alloy were evaluated for repairs. The extent of the column’s failure, the root cause of the cracking, mitigation steps, and longer term remedial actions are discussed.
Corrosion in reinforced concrete structures, such as bridges, piers, and parking garages, often occurs due to exposure to high-chloride environments.One type of structure that is often overlooked is the manmade aquarium.
Participating in technical standards development at NACE involves attending meetings...a lot of meetings. Well-run meetings are a great tool for exchanging information, working together, and developing consensus to make decisions or create documents. Here are some suggestions on how to conduct a technical committee meeting.
In Italy, where domestic nuclear power production has been halted, the need is ongoing to safely store low-level radioactive waste produced as a byproduct. The goal is to meet Italian and international requirements for temporary storage of low-level radioactive waste. The waste is stored in steel drums encased in concrete for radiological reasons. Relative humidity of 65% or lower must be maintained to prevent corrosion.
Several myths concerning the cause of reinforced concrete deterioration prevailed in the mid-20th century, but steel corrosion is by far the biggest durability issue for reinforced concrete structures.
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.
