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.
An alternative method for directly measuring effectiveness of AC-induced corrosion control and mitigation efforts. This method takes the form of traditional coupons imbedded with ultrasound testing (UT) transducers designed to directly measure and track coupon metal loss and related corrosion-induced anomalies.
This CorrCompilation series focuses primarily on equilibrium-formed scales, where an aqueous fluid changes from an unsaturated equilibrium state to a saturated and supersaturated state and then solids may start to form. These types of fouling minerals include alkaline earth salts, silicates, alkaline salts (NaCl), sulfides, and under specific circumstances, metal sulfide salts that form through equilibrium changes. While corrosion product scales are not the subject of this book, the importance of corrosion product layers to the deposition of other scales will be described.
Since this is a CorrCompilation and more than 90 copies of NACE papers are attached, the work is published in four volumes. The editor, Wayne W. Frenier, FNACE, provides an extensive introduction to each volume, offering the reader a thorough mix of history, theory, and engineering techniques and methods for addressing scale.
Volume 1: Introduction to Equipment Subject to Inorganic Scale
Volume 2: Current Mechanisms for Understanding Inorganic Scale Formation and Deposition
Volume 3: Chemistry and Application of Scale Inhibitors
Volume 4: Alternative Methods of Scale Control
This fourth volume, "Alternative Methods of Scale Control," reviews methods for controlling inorganic scale that provide alternatives to chemical SI methods or those that may be used with SIs to enhance management for an entire connected system. The first sections (1 and 2) describe non-chemical methods such as anti-scaling surfaces and electronic methods for reducing scale deposition.
