Maintenance Applications
Ultrasonic Thickness Measurement


  • Measure thickness of critical structural supports such as columns, mill rolls, derrick studs, and overhead crane wheels
  • Incoming inspection of replacement structural parts
  • Measure remaining wall thickness of piping, boilers, and tanks
  • Requires access to only one side (typically outside) of component

Recommended Gauges
Ultrasonic Flaw Detection


  • Locate and size discontinuities in structures
  • Verify integrity of welds: check for lack-of-fusion, undercuts, and cooling cracks
  • Inspect for fatigue cracking of components
  • Also addresses thickness measurement applications

Recommended Instrument
