The repair was designed with a prediction of 100 years of service life extension. This was achieved with a steel coating and a concrete coating (barrier effect) that produced a similar or better protective effect than recorded during the evaluation.
In this case study, investigators found that a buried log or root had likely affected the exterior coating on a ductile iron waste pipe. None of the inspections prior to the rupture, which spilled nearly 15 million gallons of untreated sewage, had caught the damage.
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).
The chloride concentration effect in naphtha on the corrosion behavior of carbon steel was studied by simulating conditions within naphtha hydrotreating unit equipment.
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.
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.
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.
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.
