Because the process of corrosion is highly time-dependent, the integration of monitoring technology in existing systems can also provide early warning of costly corrosion damage and provide information on locations where damage is occurring, or possibly could occur.
Solvent-borne acrylic coatings made the first significant entry into the protective coatings market as color and gloss retentive topcoats for epoxy intermediate coats. The newer waterborne acrylics represent the forefront of this technology.
Corrosion engineers are familiar with the galvanic series, which lists noble and active metals, and with galvanic corrosion. This article looks at corrosion damage to aluminum caused by direct metal-to-metal contact with copper and by contact with copper-containing solutions.
Microbiologically influenced corrosion (MIC) is a major integrity threat for water treatment systems as well as other utility water systems. This article explores the shortcomings of erroneous chemical treatments and their main root cause(s).
With the Northern Hemisphere’s 2023 hurricane season in full swing and nearing its annual peak, emerging technologies and artificial intelligence are among new tools offering hope for superior pipeline protection against mighty storms.
Bob Chalker, CEO of AMPP and formerly NACE International, explains his decision to retire in July 2023 and outlines what the transition process will look like for the association over the coming months and years.
Brad Wilder, bridge painting division manager at Intech Contracting, LLC, shares perspective on his extensive time with the company and the role of associations like AMPP in helping enable that success.
With the increasing amount of high-voltage power line corridors, pipeline crossings, and transit systems, interference threats on pipeline assets are more common. This results in a higher risk of accelerated corrosion with poor notification to the pipeline operator.
In this newly released AMPP webcast, inspection and policy experts explore the basics of the building inspection process; strategies to ensure buildings are protected; and important resources and tools. They also respond to viewer questions.
Laboratory testing using biofilms can provide a reliable means to evaluate the potential for microbiologically influenced corrosion (MIC), and subsequently, to assess the effectiveness of biocides to inhibit biofilm growth and mitigate MIC during hydrotesting and wet parking.
Kamal Taher, director of global operations at AMPP, explains what the combination of NACE International and SSPC: The Society for Protective Coatings means for industry programs such as contractor accreditation.
Any mechanical disturbance of the protective film can stimulate attack of the underlying metals until either the protective film is re-established, or the metal has been corroded away. Erosion-corrosion is encountered most frequently in pumps, valves, centrifuges, elbows, impellers, inlet ends of heat exchanger tubes, agitated tanks, and so forth.
Merging concepts like designing for purpose, maintaining with integrity, and decommissioning with a second life in mind are ideas that, if used in conjunction with adequate management tools, can help industries pursue the path of applying an effective corrosion management system.
As published in the January 2021 issue of Materials Performance (MP), this article explores the required elements for stress corrosion cracking to occur. Typically, these involve a susceptible alloy, the proper chemical environment, and an enduring tensile stress.
Having launched on January 6, 2021, the new organization, Association for Materials Protection and Performance (AMPP), represents a combination of NACE International and SSPC: The Society for Protective Coatings.
