Ultrasonic Thickness Gauges: Benefits of Sonic Readings

As we’ve discussed in previous articles, Ultrasonic technology is a reliable method of inspection with a wide variety of applications. In addition to being used for flaw detection, ultrasonic technology can also be used to determine the thickness of metallic pipes, storage tanks, boilers, and vessels (to name a few applications). Learn more about the benefits of this process below.

How it works

Just like ultrasonic flaw detection, thickness gauges use ultrasonic sound waves to get an accurate read of the remaining wall thickness or components that are subject to corrosion or erosion. Thickness is determined by sending out pulses and measuring the time it takes for the sound to travel from the transducer, through to the far side of the component, and back to the transducer. Signal travel times are converted to remaining wall thickness by the instrument and displayed in Imperial or Metric units.

Reasons for Use

Getting an accurate reading of the thickness of your pipes, boilers, or vessels helps ensure their safety and fitness for service. Over time, corrosion and erosion can degrade the component, leading to safety hazards (leaks or breaks), or the need for replacement. Regular inspection will keep you on top of repairs, reducing overall cost and extending the longevity of your plant pressure components.

Diverse Applications

UItrasonic Thickness Gauges are frequently used to monitor the thickness of steel components used in off-shore construction, pipelines, and more. It can be used to monitor corrosion through wall thickness measurements, and can also test ductile iron and/or plastic pipes. Testing is quick, does not require access to both sides of the sample, can test through coatings and linings, and provides extremely accurate readings (usually to within +/- .002)
