Description
Ultrasonic Wall Thickness Gauges
Ultrasonic Wall Thickness Gauges (ultrasonic thickness gauges, ultrasonic thickness testers, ultrasonic thickness meters, UT gauges, etc.) measure the wall thickness of materials such as steel, plastic, and more using ultrasonic technology. Ultrasonic Thickness Gauges are ideal for measuring the effects of corrosion or erosion on tanks, pipes, or any structure where access is limited to one side. Multiple echo Thru-Paint models (UTG M) measure the metal thickness of a painted structure without having to remove the coating.
What is Ultrasonic Thickness Measurement?
Ultrasonic thickness measurement techniques are used to measure a wide range of substrates and applications for loss of material thickness due to corrosion or erosion. Ultrasonic Thickness Gauges are designed for measuring the thickness of metallic (cast iron, steel, and aluminum) and non-metallic (ceramics, plastics, and glass) substrates and any other ultrasonic wave-conductor provided it has relatively parallel top and bottom surfaces.
An ultrasonic thickness gauge facilitates rapid inspection of the thickness of large metallic structures at small measurement intervals, providing a high-detail thickness map of a scanned surface. When access is only available from one side of the substrate, ultrasonic wall thickness measurement is the most efficient way to monitor the effects of erosion or corrosion and is instrumental to both quality assurance and quality control.

Principles of Operation of Ultrasonic Wall Thickness Gauges
Why Measure Wall Thickness with Ultrasonic Thickness Gauges?
Erosion
Erosion is the process by which a protective coating or substrate is worn away by friction resulting from repetitive mechanical interaction. Typical causes of erosion include cavitation, impingement by liquid or solid particles, and relative motion against contacting solid surfaces or fluids.
Corrosion
Corrosion is the process by which a substrate and its properties are damaged or worn away by a chemical action or change. In metals, deterioration attributed to corrosion is most often caused by an oxidation process.
Erosion and Corrosion Testing
Using non-destructive inspection methods minimize safety concerns, ensure code compliance, and reduce the frequency of major repairs (and subsequently costs). As an example, marine applications have a significant risk of catastrophic substrate failure due to undetected substrate corrosion or erosion. However, costs associated with corrosion or erosion damage can be more subtle. Consider the case of a propeller blade that has experienced wear or damage. A likely impact is a decrease in the efficiency of the propeller, translating directly to a decrease in horsepower and an increase in turbulence (vibration). This results in a decrease in maximum speed and an increase in fuel consumption. Furthermore, cavitation caused by the damaged propeller creates a surrounding environment that is even more damaging to the propeller itself.
