Ultrasonic thickness testing
Remaining-wall measurements for piping, vessels, tanks, structural members, and marine assets.
Conventional ultrasonic inspection
Ultrasonic Testing Services
Ultrasonic testing uses high-frequency sound to measure remaining wall thickness and evaluate internal conditions without damaging the asset.
Inspection done right
Reliable results for critical assets
NVI performs conventional ultrasonic thickness measurements and pulse-echo flaw detection for maintenance, fabrication, corrosion monitoring, and condition assessment programs.
Inspection points, calibration, surface conditions, material, and acceptance criteria are addressed in the procedure and field plan. Results can be integrated into mechanical integrity databases and repeat inspection programs for trending.
