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

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
