Case Histories

The Future of Machine Learning on Corrosion

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.

Preventing Refinery Corrosion by Process Monitoring, Predictive Analysis

Because refinery operations are so complex, and obtaining accurate asset integrity information has proven to be a challenge, a need exists for quantifying corrosion.

Antarctica—Corrosion in a Polar Desert

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.

NACE International’s Annual Corrosion Career Survey Results for 2015

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.

Belzona Case Study on Pipeline Protection

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.

Wanted: Technical Articles for MP

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.

Failed Anchor Rods on the San Francisco-Oakland Bay Bridge: A Corrosion Discussion

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.

Cladding Protects Vessel from Sulfide Stress Cracking in Sour Service

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 Public Aquariums

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.

How to Conduct a Technical Committee Meeting

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.

Battling Corrosion in Nuclear Waste Storage Facilities

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.

Corrosion Effects on the Durability of Reinforced Concrete Structures

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.

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.

Localized Corrosion Failure of a Hydraulic Pipeline in a Subsea Gas Well

After 10 years of normal operation, a hydraulic circulation pipeline of a subsea gas production well failed at its bend zone due to internal localized corrosion attack. This appears to be related to crevice corrosion and pitting.

Chemically Bonded Phosphate Ceramics Provide Corrosion Protection for Storage Tanks

A variety of industrial facilities with structures constructed of carbon steel are at risk of corrosion. An inorganic spray-on protective coating technology provides corrosion protection to metal through a chemically bonded phosphate ceramic.
