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.

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.

Dynamic Pulsed Eddy Current Inline Inspection Technology Assesses Unpiggable Pipelines

To assess internal and external corrosion in piping configurations that are unpiggable or difficult to assess, a novel dynamic pulsed eddy current technology integrated with a robotic inline inspection tool was developed that is capable of internally inspecting metallic pipes.

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 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.

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.

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.

Cathodic Protection for Water Mains in a High-Consequence Transit Corridor

To protect pipelines in a transit corridor where they crossed underneath the light-rail tracks, construction of the line included retrofitting the pipelines with a precast concrete box culvert casing and installing an impressed current cathodic protection (ICCP) system.

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.

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 Task Group Report Focuses on Sustainability of Wastewater Systems

An increasing number of water and wastewater systems, structures, and components in the United States are being affected by corrosion and deterioration, which can shorten the life span of the system and increase costs for the consumer. To increase awareness of the corrosion problems encountered by municipal wastewater systems, members of NACE Task Group (TG) 466 recently published a report, “Corrosion Problems and Renewal Technologies in Wastewater Systems.”
