An investigation and testing on a fractured premium joint tubing string in a high-pressure, high-temperature well determined the failures were caused by stress corrosion cracking.
U.S. and U.K. researchers are working together on the development of real-time sensing systems to alert maintenance engineers of cracks in transportation infrastructure.
Underdeposit corrosion (UDC), a general term that refers to localized corrosion that develops beneath or around deposits on a metal surface, is a phenomenon that leads to pipeline failures and is one of the most damaging forms of corrosion for oil and gas pipelines. It can occur in subsea water injection pipelines, well-fluid pipelines, and large-diameter transmission lines.
Using nanobiotechnology and a process known as solid-state fermentation, university researchers are making concrete that regenerates to repair cracks as they develop.
A new study from the Global Brake Safety Council suggests the use of substandard materials and processes in automobile brake pads could be leading to accelerated failure modes. The council was formed in 2014 to advocate and raise awareness for high standards in brake safety while ensuring responsible manufacturing in the automotive industry.
Case studies were recently conducted to test the ability of a robotic system to potentially perform corrosion under insulation (CUI) inspections in oil, gas, and petrochemical environments.
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.
Although corrosion is a common problem coal in mines, as are material failures, there has been limited documentation of these issues in the literature or at conferences.
Funded by the European Commission, this new project involves the design of a portable, three-dimensional ultrasonic scanner for the nondestructive testing and evaluation of concrete in bridges and other building structures.
Highlights of the study include data on pipe material break rates; the analysis of age and corrosion in failure modes; observations on pressure, delivery demands, and the effects of soil corrosivity; and new metrics for pipe replacement rates.
The design of the modular corrosion test rack by University of Alaska Anchorage researchers allows it to be adjusted to three different exposure angles. This rack helps isolate corrosion-inducing variables in cold climates and their primary effects on corrosion.
During its first 34 years in service, Canada’s Arvida Aluminum Bridge sustained some corrosion damage that required work. After a further ~30 years in service, the bridge was inspected to determine the effectiveness and longevity of that repair work. This article describes the corrosion damage, the repair work, and the current condition of the bridge.
Utilizing the energy potential in high-power geothermal wells can be expanded with materials that withstand the extreme environmental conditions.
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.
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.
