The ROVs measure metal thickness, paint thickness, and cathodic protection (CP) voltage—a corrosion prevention technique the Navy uses that charges the hull at a certain voltage to slow down corrosion.
Because refinery operations are so complex, and obtaining accurate asset integrity information has proven to be a challenge, a need exists for quantifying corrosion.
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.
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.
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.
In a new report on corrosion inside underground storage tanks storing diesel fuel, the U.S. Environmental Protection Agency found moderate or severe corrosion could affect metal components inside both steel and fiberglass tank systems.
Water utility officials in Arlington, Texas, are working with University of Texas at Arlington researchers to inspect concrete manhole shafts and sewer pipes for corrosion, cracks, and other internal defects.
Airmen with the 19th Maintenance Squadron at the Little Rock Air Force Base in Arkansas are using nondestructive inspections to identify potential cracks in a variety of aircraft parts.
A collaborative project funded partly by the U.K. government is looking to develop cost-effective sensors capable of measuring the corrosion rates of metals used in water-based heating and cooling units.
In a CORROSION 2017 paper, authors discussed two water wall tubes in a multistage flash distillation plant’s operating boiler that experienced failure after 14 years of service.
Russian scientists recently used a thermal imaging technique to study the corrosion of steel reinforcement within 14 reinforced concrete pillars.
A recent study from European university scientists suggests that samples of reinforced concrete need to be larger to ensure accuracy in corrosion detection.
According to U.S. researchers, a localized form of nanoscale corrosion appears responsible for unpredictably decreasing the working life of steel pipes used frequently in the oil and gas industry.
Average annual salaries in 2016 are reported for corrosion professionals in the United States, Canada, United Kingdom, and Europe. A slight gain was seen for the United States and United Kingdom, while a larger increase was recorded in Canada.
Industrial and research partners are collaborating to investigate alternative inspection methods on wind turbines through the use of acoustic emissions monitoring systems and offshore drones equipped with thermal imaging cameras.
