Corrosion Basics

Remedial Measures for Reinforced Concrete Structures

A number of fundamental measures can be taken to address the problem of reinforcing steel corrosion. However, an important distinction has to be made in the applicability of remedial measures to new versus existing structures.

Corrosion Basics: Polymeric Materials

When compared with metals, polymeric materials tend to be more resistant to chloride ions and hydrochloric acid. However, polymeric materials are generally weaker and softer; less resistant to concentrated sulfuric and oxidizing acids and solvents; and subject to temperature limitations.

Corrosion Basics: Testing and Monitoring in Manufacturing Plants

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.

Corrosion Basics: Acrylic Coatings

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.

Examining Galvanic and Deposition Corrosion

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.

Chemical Treatment Shortcomings Related to MIC Control

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).

Advances in Protecting Pipelines from Hurricane Damage

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.

Interview: Bob Chalker on His Retirement and AMPP’s Future

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.

Bridging Gaps: Intech’s Brad Wilder Shares Keys To Success

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.

Mechanistic Modeling for Integrated External Corrosion Management

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.

Why Corrosion Inspections Are Important to Community Safety

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.

Managing MIC During Hydrotesting and Wet Parking

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.

How the Launch of AMPP Affects Global Operations

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.

Failure Analysis and Design Considerations: Fluid Velocity Effects

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.

A Circular Economy Approach from a Corrosion Engineer

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.
