U.S. Navy Adopts Composite-Patch Repair Method for Aluminum

Engineers at the U.S. Naval Surface Warfare Center are now utilizing a new composite-patch repair method for incidents involving stress corrosion cracking on aluminum substrates.

Corrosion-Resistant Alloys in Downhole Applications

The authors discuss different material selection procedures, case histories of corrosion, and cracking of corrosion-resistant alloys (CRAs) and specific selection criteria of CRAs for application in downhole conditions.

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.

Testing, Inspection, and Rehabilitation of Offshore Cast Iron Pipes

The City of San Francisco needed to determine the condition of offshore pipelines and their support structures and whether they were fit to continue operating, needed repairs or replacements, or required coating or lining repair.

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.

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.

U.S. Researchers Probe Localized Corrosion on Steel Pipes

According to U.S. researchers, a localized form of nanoscale corrosion appears responsible for unpredictably decreasing the working life of steel pipes used frequently in the oil and gas industry.

Self-Healing Polymer Cement Offers Concrete Alternative

Researchers at the U.S. Pacific Northwest National Laboratory say their new self-healing cement technology could eliminate the need to remove, repair, and replace cracked cement wells.

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.

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.

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.

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.

Neighborhood—An Influential Factor for Material Damages

This article highlights the impact of routine surrounding conditions as well as unusual neighborhood events on the integrity of process equipment and piping.

Equipment, Materials, and Corrosion in the Biodiesel Industry

The biodiesel industry requires utilizing corrosion- and degradation-resistant materials due to characteristics related to the chemical reagents and catalysts used in the production process and to those of the fuel itself.

Diagnostic Study of 10-inch Duplex Stainless Steel Flowline Weld Failure

This article discusses the failure investigation performed for a major operator in the Middle East on duplex stainless steel (DSS) flowline welds. The subject flowline was used intermittently since 1984 in an extreme sour service chloride-containing corrosive environment.
