Modeling Helps Reduce Corrosion in Refineries

Corrosion can be a significant challenge for refiners in downstream operations, and one of the key factors in causing corrosion in crude distillation unit overheads is hydrochloric acid (HCl).

Influence of Organic Chloride Concentration on Carbon Steel

The chloride concentration effect in naphtha on the corrosion behavior of carbon steel was studied by simulating conditions within naphtha hydrotreating unit equipment.

X-Ray Analysis Sheds Light on Artifacts from Henry VIII's Warship

Twenty-first century x-ray technology has allowed University of Warwick scientists to peer back through time at the production of the armor worn by the crew of Henry VIII’s favored warship, the Mary Rose.

Corrosion Impact of Offshore Platforms, Structures, and Vessels

A review was carried out on the impact of corrosion on offshore platforms, vessels, and structures in the Trinidad and Tobago Atlantic Ocean environment. This article analyzes carbon steel coupons placed at different points on steel piles.

Corrosion Behavior of a Novel Material—Open-Cell Aluminum Foam

The authors studied open-cell aluminum foams with different pore densities under marine conditions, with the objective of learning more about the corrosion behavior of these materials. The resulting deeper understanding is expected to lead to expanded utilization in advanced engineering applications.

Bend Test of Concrete Power Poles

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.

Corrosion-Induced Failure of Bridge Post-Tensioning Tendons

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 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.
