Power Generation (Nuclear & Fossil Fuel) Applications
Ultrasonic Thickness Measurement


  • Measure remaining wall thickness of corroded or eroded metal piping, valves, and storage tanks
  • Verify wall thickness prior to weld repairs
  • Measure remaining wall thickness through paint and protective coatings
  • Requires access to only one side (typically outside) of piping
  • Measures at elevated surface temperatures to 650 degrees F

Recommended Gauges
  • T-Mike E
  • T-Mike ES with high speed scanning and minimum thickness display
  • T-Mike EL with datalogger for permanent documentation of thickness readings
  • T-Scope III (measure through coatings)
Ultrasonic Flaw Detection


  • Locate internal defects such as laps, porosity, and forging defects in piping, valves, and storage tanks
  • Verify integrity of welds: check for lack-of-fusion, undercuts, and cooling cracks
  • Locate and size discontinuities in structural components
  • Also addresses thickness measurement applications

Recommended Instrument

Ultrasonic Bolt Stress Measurement


  • Verify tension on installed manway studs in nuclear reactors
  • Confirm uniform loading of gasketed flange bolts
