Corrosion Basics

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.

Corrosion Basics: Stress Corrosion Cracking

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.

Association for Materials Protection and Performance (AMPP) Is Formed

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.

Some Aspects of Steam Condensate Corrosion

Diligent boiler feedwater treatment, involving mechanical deaeration and chemical treatment, is the primary defense against steam condensate corrosion. This article reviews further methods, including equipment design, materials selection, venting, reducing air ingress, and selecting steam traps.

Corrosion Impact of Offshore Platforms, Structures, and Vessels

A review was carried out on the impact of corrosion on offshore platforms, vessels, and structures in the Trinidad and Tobago Atlantic Ocean environment. This article analyzes carbon steel coupons placed at different points on steel piles.

Bend Test of Concrete Power Poles

Concrete beams should be resistant against the influence of corrosive agents, environmental degradation, and mechanical forces. In this article, the effect of two different concrete mixing designs is investigated against the pole’s bend strength behavior.

Corrosion-Induced Failure of Bridge Post-Tensioning Tendons

This article presents an overview of corrosion-related issues that have been disclosed on post-tensioned bridges in both the United States and Europe.

Corrosion Management and Risk-Based Inspection

Risk-based inspections are believed to be one of the most efficient types of inspections, based on numerous evaluations of site visits and of asset integrity audits.

Corrosion Basics: ICCP for Atmospherically Exposed Reinforced Concrete Structures

Impressed current anodes for atmospherically exposed steel in concrete are very different from anodes for underground and underwater applications.

Corrosion Basics: Open Recirculated Cooling Water Systems

There are certain fundamental considerations that should be understood in relation to open recirculated systems.
