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.
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.
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.
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.
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.
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.
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.
With a properly implemented corrosion management program, corrosion decisions and practices can be integrated within an organizational management system for oil and gas pipelines.
A preliminary U.S. report determined that errors were made in the design of the pedestrian bridge’s main span, where two truss members were connected to the deck.
Industry engineering experts describe several cracking-related damage mechanisms and discuss control measures to mitigate corrosion and cracking in refinery units.
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.
With the winter season underway in the Northern Hemisphere, a university research team is developing a more sustainable deicing solution for road infrastructure using grape skins and other agricultural waste.
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.
The nature of duplex stainless steels (SS) makes them susceptible to failures observed in both austenitic and ferritic SS. Improper fabrication techniques lead to deleterious sigma and alpha prime phases, causing brittle failure.
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.
