Corrosion Management for Pipeline Integrity Roundtable: Part 1

With a properly implemented corrosion management program, corrosion decisions and practices can be integrated within an organizational management system for oil and gas pipelines.

Control of Environmental Degradation of Concrete Power Poles

Since significant funds are expended for replacement, an investigation was launched into the effects of mechanical activity and corrosion in the degradation of the concrete poles.

Research Team Examines Pipeline Failure Prediction Models

In a new study, researchers at Concordia University and the Hong Kong Polytechnic University examine many methodologies currently used by industry and academics to predict pipeline failure—and their limitations. The researchers cite more than 10,000 pipeline failures in the United States alone as the motivation for their research, according to U.S. Department of Transportation data.

Investigators: Corroded Pipe Led to U.S. Refinery Explosion, Fire

Investigators with the U.S. Chemical Safety Board say a June 2019 explosion and fire at the Philadelphia Energy Solutions (PES) refinery in Philadelphia, Pennsylvania, USA, occurred due to a corroded pipe elbow in the refinery’s alkylation unit.

U.S. Marine Corps Tests New Cold Spray Technology

The cold spray process bonds metal to metal in a relatively low-heat environment in order to deposit a coating onto the substrate. If the process is approved, the technology could help reduce turnaround times and decrease repair costs.

Modeling Corrosion Resistance of Reinforced Concrete Structures

The total present cost and lifecycle cost show that galvanized steel rebar provides the most cost-effective protection for reinforced bridge decks with a 100-year service life.

General Motors Boosts Corrosion Prevention at New Assembly Plant

The $1.4-billion plant expansion in Arlington, Texas, USA, includes new robotics procedures and superior coating technologies, which are designed to enhance the corrosion resistance of automobiles.

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.

IMPACT Study Breaks New Ground in Corrosion Management Research and Practice

This article provides a summary of the scope, approach, and significant findings of NACE International’s recent IMPACT study, including corrosion control strategies that could save hundreds of billions of dollars per year.

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.

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.

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.

Significance of Evaluation Methods for Surface-Applied Inhibitors

This article discusses the performance and relative importance of a recent testing program for corrosion inhibition and other performance parameters using documented test methods.

Nickel-Rich Coating for Saline-Alkali Soil Grounding

To improve the corrosion resistance of the grounding grids in saline-alkali soil, the authors fabricated a conductive and anticorrosive coating. After a series of tests, results indicated that an increase of nickel powder in the coating can lead to its electrical conductivity enhancement.
