The Science Behind It: Corrosion Caused Lead-Tainted Water in Flint, Michigan

Learn more about the Flint, Michigan drinking water crisis caused by corrosion in this new quarterly special feature, The Science Behind It. Read the MP article to get the basic facts, and then explore the science behind the corrosion problem, which is presented in several related CORROSION articles.

Localized Corrosion Failure of a Hydraulic Pipeline in a Subsea Gas Well

After 10 years of normal operation, a hydraulic circulation pipeline of a subsea gas production well failed at its bend zone due to internal localized corrosion attack. This appears to be related to crevice corrosion and pitting.

Nanocoatings Deliver Performance and Operational Advancements

Carbon nanotechnology advancements and their use in a new coating address the ever-growing demand from asset owners to obtain sustaining and economically viable coating solutions.

Detecting Pipeline Stress Corrosion Cracking through Direct Assessment

External corrosion direct assessment (ECDA), a structured process intended to assess, manage, and reduce the impact of external corrosion on pipelines, was used to detect stress corrosion cracking in a buried natural gas transmission pipeline in Pakistan.

Drones Help Detect Corrosion under Insulation

To address the challenges of detecting corrosion under insulation (CUI), two companies have partnered to provide remote imaging technology with unmanned aerial vehicle (UAV) surveillance to inspect insulated piping and components.

Chemically Bonded Phosphate Ceramics Provide Corrosion Protection for Storage Tanks

A variety of industrial facilities with structures constructed of carbon steel are at risk of corrosion. An inorganic spray-on protective coating technology provides corrosion protection to metal through a chemically bonded phosphate ceramic.

Flexible Coatings Help Protect Marine Structures

Corrosion impacts all structures in a marine environment, such as offshore platforms and rigs and ocean-going vessels. One way to minimize and mitigate the effect of some types of corrosion is through the use of flexible surface coatings.

Selecting Stainless Steels for Seawater Pumps

Pumps are routinely used to handle seawater. With the increasing demands for low maintenance and reliable operation, it is important that suitable corrosion-resistant materials are selected for pumps used in seawater.

NACE Specific Technology Group Provides Railcar Industry Standards

Specific Technology Group (STG) 43, “Transportation, Land,” promotes the development of techniques to extend the life of land transportation equipment. The committee primarily focuses on writing standards and reports on industry best practices for coating application and corrosion control in and on railcars.

Chromate Primer Alternative Uses Carbon Nanotubes Modified with Corrosion Inhibitors

Scientists have developed a non-chrome primer system by incorporating carbon nanotubes (CNTs) modified with organic corrosion inhibitors into an epoxy-based resin. The goal of the coating development effort was to identify promising CNT-containing non-chrome primer formulations that perform comparably to traditional chromated ones.

Corrosion Monitoring and Inhibitors for Production Tubing in Gas Wells

In oil and gas installations, the production tubing is critical in producing fluids from the reservoir. Corrosion of production tubing not only hampers production from the well, but replacement costs are significant, requiring special work-over jobs. Monitoring production tubing to identify corrosion problems and using inhibitors to extend service life is discussed.

Wire/Strand Slippage—A Potential Failure Mode for Post-Tensioning Tendons

A forensic investigation of unbonded, post-tensioning tendons on a large structure revealed relatively advanced levels of strand corrosion within and inboard of the end anchors. Strand corrosion within anchors was so advanced that wires had disengaged from the wedges, resulting in slip, contraction, and consequent load reduction in the strand.

Correcting Concrete Corrosion

Corrosion of the reinforcing steel in concrete is a worldwide problem that causes a range of economic, aesthetic, and utilization issues. However, if corrosion effects are considered in the design phase and the right decisions are made prior to construction, buildings can be constructed to resist corrosion.

Corrosion Risks and Mitigation Strategies for Offshore Wind Turbine Foundations

An increasing number of wind turbine structures have been installed, particularly on monopile foundations. Corrosion experiences and mitigation strategies reported by the offshore wind energy industry for these foundations are discussed.

Corrosion of Copper Alloys in Consumer Electronics Environments

Results of corrosion testing on eight alloys from five copper alloy families commonly used in the consumer electronics industry are presented. Short-term exposures were conducted in simulated consumer environments such as a salted carbonated cola beverage, artificial human perspiration, and phosphate-buffered saline.
