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.

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.

Investigators: Design Issues Behind Florida Bridge Collapse

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.

Fabrication Practices to Mitigate Risks of Refinery Corrosion Cracking

Industry engineering experts describe several cracking-related damage mechanisms and discuss control measures to mitigate corrosion and cracking in refinery units.

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.

Researchers Propose Less Corrosive Alternative to Road Salt

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.

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.

Stress Cracking of Duplex Stainless Steel in Refining

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: 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.

New Welding Technique Could Reduce Corrosion of Automotive Parts

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.

Researchers Concerned by Current Models for Nuclear Waste Storage

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.

Access-Fitting Position in Corrosion Management Programs

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.

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.
