Researchers Suggest New Method to Create Corrosion-Resistant Alloys

A new study suggests that a better protective oxide scale can be achieved in high-temperature Al alloys by controlling the size distribution of reactive element particles. These types of alloys are prevalent in many industrial sectors and applications.

The Humble Building Material that Shelters Millions Across the Globe

Corrugated iron has been and continues to be an invaluable building material that deserves to be taken seriously. It shows that steel can be simply and cheaply formed to a useful shape, protected from corrosion by a range of coatings, and made accessible to citizens in all corners of the globe.

Water Repellency Technology Mitigates Corrosion Under Insulation Risk

The hydrophobic WR-Tech additive leads to stone wool, mandrel-wound pipe sections with significantly less water absorption relative to industry standards; faster drying rates; and durability over a wide range of potential CUI temperatures.

Study: Microbial Corrosion Led to California Gas Leak

An investigative report into the 2015 blowout of a natural gas well near Los Angeles, California, USA, cited corroded pipe casings, safety failures by a utility, and inadequate regulations as incident causes.

Chemistry to Tame the Power of Steam

As steam is produced in a boiler, the impurities left in the feedwater concentrate and precipitate out of the solution and onto the internal surfaces of the boiler, causing fouling. This reduces both the water flow and the heat transfer, decreasing the efficiency and power of the boiler. Such fouling can accelerate corrosion of the boiler, decreasing its life.

New Method for Repairing Damaged Concrete Bridge Girders

Researchers with the Minnesota Department of Transportation and the University of Minnesota have successfully tested a new, cost-effective method for repairing damaged bridge girders that they believe can restore them to their original shear strength or even make them stronger.

Novel Phosphonate Proves Useful in Geothermal Environments

The researchers conclude that the novel phosphonate chemistry is useful in ultrahigh geothermal applications. Its high tolerance to calcium, biodegradability, thermal stability, and good performance against calcium carbonate scaling prove valuable in many environments.

Chemical Safety Board: Thermal Fatigue Led to Gas Plant Blast

In their final report, U.S. investigators say thermal fatigue in a heat exchanger likely caused a major hydrocarbons release in June 2016. This resulted in a series of fires and explosions at the Enterprise Products gas plant in Pascagoula, Mississippi.

Internal Corrosion Protection Strategies for Aboveground Storage Tanks

In a CORROSION 2019 conference paper, the authors analyzed two case studies of corrosion-prone tanks using dissimilar metals and the challenges that arose in providing them with adequate cathodic protection (CP).

New Metal Alloy Materials Slow Corrosion in Process Vessels

In this case study at a U.S. oil and gas facility, a new high-velocity thermal spray cladding solution helped stop corrosion where an older nickel-copper thermal spray coating and organic patch repairs had worn away.

New Accident-Tolerant Fuel Cladding for Nuclear Environments

A multi-year research project involving Oak Ridge National Laboratory has led to the production of an accident-tolerant fuel cladding utilizing iron-chromium-aluminum alloys.Since the disaster at Japan’s Fukushima Daiichi Nuclear Power Plant in March 2011, scientists and engineers have searched for solutions to help prevent future accidents of that magnitude.

Corrosion Management for Pipeline Integrity: Part 2

In the final part of this series, three experts in oil and gas pipeline corrosion management explain the value of corrosion management systems, how they work, and what programs and platforms are available to help organizations improve their performance.

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.
