Water-Based Corrosion Inhibitors for Reinforcing Bars

Open circuit potential, electrochemical polarization, salt spray testing, and immersion testing in sodium chloride solution were employed to evaluate the anticorrosive ability of the water-based conversion film.

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.

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.

Corrosion Management and Cost Optimization

A better appreciation of the various components of typical corrosion costs in the oil and gas industry could further facilitate their optimization.

Study: North American Waterways Becoming Saltier, More Alkaline

University researchers find significant increases in both salinization and alkalinization of U.S. streams and rivers, which can influence the water's corrosivity.

A Multifunctional Additive for Controlling Inorganic Foulants in Industrial Water Systems

This article presents performance data on polyamino polyether methylene phosphonic acid (PAPEMP) on various mineral scales commonly encountered in boiler, cooling, desalination, geothermal, gas, and oil systems.

Internal Stress Corrosion Cracking of Shale Gas Flowlines

A reaction between high-pH monoethanolamine and carbon dioxide formed a carbonate/bicarbonate solution that led to intergranular stress corrosion cracking.

Corrosion Prevention Using Real-Time Data in Oil Fields

In corrosion monitoring of oil and gas fields, there are many techniques that can provide data. Modern high-resolution corrosion monitors, including electrical resistance probes, are available. These instruments can be installed in key locations and connected to a control room computer.

Linking Microbiologically Influenced Corrosion to Microbiological Activity Using Molecular Microbiological Methods

While there are solutions to mitigate microbiologically influenced corrosion, a big challenge is to make the connection between corrosion damage and the activity of microorganisms.

Corrosion Issues of Carbon Capture, Utilization, and Storage

When steels corrode under a high-pressure, high-temperature multiphase environment containing supercritical carbon dioxide, various gas impurities, salts, crude oil, and solid particles merit further investigation.

The Science Behind It: A ‘Cultural’ Change in Detecting Microbiological Activity

Molecular microbiological methods (MMM) are becoming more commonly used as an alternative for culture-based methods for estimating bacterial numbers in oilfield systems.

Preventing Internal Corrosion in Oil and Gas Field Pipelines

Preventing the internal corrosion of crude oil, natural gas, and water injection pipelines involves numerous steps, which operators should follow to ensure the integrity of oil and gas field pipelines that are essential for uninterrupted production.

Vapor Corrosion Inhibitors for Tank Bottom Corrosion Control

A study was recently conducted to determine the viability of vapor corrosion inhibitor (VCI) technology in mitigating corrosion. Overall, VCIs were found to be effective in mitigating corrosion when recommended dosages are used, and they could also be used in combination with impressed current CP systems.

New Steel Pickling Process Applied Without Nitric Acid

The usual challenge for stainless steel pickling involves removing all scale, iron contamination, and welding oxides to achieve a fully passivated surface with an even, clean, and aesthetic finish. In this case, a new nitric-acid-free process was installed at a large beer barrel plant in Spain.
