Materials Selection & Design

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.

Strategic Planning at NACE International: Seventh in a Series

The plan for success has three elements: key strategic initiatives, implementation plans, and review and reload sessions. In this month’s post, we introduce all three steps in the plan for success process.

Radiation Backscatter-Based Nondestructive Technology Detects Corrosion under Insulation on Offshore Oil and Gas Platforms

One of the most common forms of corrosion found in the offshore oil and gas industry is corrosion under insulation (CUI). Many components on offshore platforms, such as piping systems, pressure vessels, tanks, and other equipment, are insulated for personnel protection and/or to keep fluids at appropriate temperatures for process efficiency. When insulated equipment is exposed to the harsh offshore marine environment (salt spray and mist), the ingress of chloride-laden moisture into the insulating material renders the underlying metal substrate vulnerable to accelerated localized corrosion, which often goes undetected.

Pipeline Corrosion Issues Related to Carbon Capture, Transportation, and Storage

For the foreseeable future, fossil fuels will continue to be the dominant source of the world’s primary energy production. There has been growing concern that the use of these carbon-based fuels produces greenhouse gases, principally carbon dioxide (CO2), which adversely affect the global climate and environment. One way to mitigate the problem is to use carbon capture, transportation, and storage (CCTS) techniques and systems.

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.

Wineries: Equipment, Materials, and Corrosion

Although wine production is one of the oldest industries established by humankind, the modern wine industry utilizes special equipment, mostly made from austenitic stainless steel, to avoid corrosion, scale formation, and the appearance of contaminants. Additional engineering materials used are fiber-reinforced plastics, glass for bottles, and wood for tonels and casks.

Discussion on Distribution Policy for NACE/ISO Standards

For many years, NACE International has worked with the American National Standards Institute (ANSI), the U.S. member of the International Organization for Standardization (ISO), to adopt ISO standards. Recently, NACE received notice that ISO no longer allows free distribution of nationally adopted ISO standards and members must be charged for nationally adopted ISO standards. Commentaries from several members are presented.

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.

Corrosion Inspection by 3D Non-Contact Profilometry

Corrosion can either take place locally to form a pit or crack, or it can extend uniformly across a wide surface. Proper surface analysis of the corroded sample is vital for evaluating corrosion characteristics and mechanisms, so the best materials, protective coatings, and corrosion-control measures can be selected.

Proper Coating Adhesion for Water and Wastewater Environments

Proper Coating Adhesion Is Essential for Long-Term Performance in Water and Wastewater Environments. Corrosion is a highly probable occurrence in water/wastewater facilities that can cause expensive repercussions and downtime. High levels of exposure to corrosive elements such as water, salt, acid, and chlorine are common, and there is a risk of irreparable damage to electrical equipment from corrosion. Therefore, electrical systems must be designed with the proper protection.
