Advances in precision, fully-digital ultrasonic wall-thickness measurement systems with cellular data back-haul enable accurate, deployable, and cost-effective corrosion monitoring systems. Comparisons are presented. This paper includes design principles of this next-generation platform, end-user input, and recent installation and operational experiences.
Comparisons with improved data accuracy of installed sensors in lieu of larger quantities of manual spot data are presented. This paper will include the design principles used in the creation of this next-generation platform, end-user input used to refine the design, and recent installation and operational experiences.
A laboratory study was performed by exposing seven candidate heat exchanger alloys to simulated 2 (sCO2) Brayton power cycles. The alloys, consisting of fineirtriaitilcly s 3te.6e%ls ,O austenitic stainless steels, and nickel-base alloys, were exposed to impure CO2 containing 2 and 5.3% H2O at a constant pressure of 200 bar.
The corrosion process of carbon steel in the presence of silica sand deposit in chloride-containing solution at 30 °C was monitored by use of electrochemical noise (EN). Results demonstrated that electrochemical noise with recurrence quantification analysis is useful for monitoring localized under deposit corrosion.
