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.
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.
Through testing and computer simulations, a research collaboration is working to show that a new welding technique could make the joint between light metal alloys more resistant to corrosion.
Research at The Ohio State University shows that the materials used by many countries to store high-level nuclear waste will likely degrade faster than expected due to the way those materials interact with each other.
In upstream industries, corrosion monitoring is an indispensable feature in corrosion management. Corrosion coupons and corrosion probes can make a valuable contribution toward the understanding and control of a corrosion problem.
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.
Even when corrosion inhibitors are injected into flowlines, oil and gas companies are still seeing an increase in corrosion-related leaks. Reasons include low fluid velocity, greater water cut, and sulfite-reducing bacteria in production streams.
A primer with ideal corrosion resistance and mechanical properties was developed by using waterborne saturated polyester, waterborne crosslinking agents, and Cr-Pb-free pigments and fillers with low-VOC content.
Researchers and technology specialists in Denmark are working to develop a self-powered corrosion sensor to install inside steel-reinforced concrete structures, such as bridges.
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.
