Oil/Petrochemical Applications
Ultrasonic Thickness Measurement

Application(s)

  • 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

Application(s)

  • 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

Application(s)

  • Verify tension on installed bolts and fasteners used to brace the legs of offshore oil platforms
  • Confirm uniform loading of gasketed flange bolts in pipelines
  • Verify the tension of pressure vessel, reactor and heat exchanger bolts
