Ultrasonic Testing (UT)

Ultrasonic Testing (UT) is one of the most widely used non-destructive testing methods in the industry. QMS Asset Integrity provides NATA-accredited ultrasonic testing services serving the oil and gas, marine, mining, defence, and manufacturing sectors across Australia.

Our qualified technicians use precision A-scan equipment to evaluate material thickness, detect sub-surface flaws, and map corrosion profiles on a wide range of metallic assets - from pipeline systems and pressure vessels to structural steel and marine components.

Whether you need routine in-service thickness surveys, pre-commissioning inspections, or shutdown support, our UT capabilities deliver the accurate, repeatable data your asset integrity programme demands.

Conventional UT uses a piezoelectric transducer that generates high-frequency sound waves (typically 1–10 MHz) into the test material. The sound travels through the component and reflects off the back wall or any internal discontinuity. An A-scan display on the instrument visualises these reflections, allowing the technician to determine wall thickness or characterise flaws.

At QMS we deploy contact and immersion coupling techniques, selecting probe frequency and angle to match the material, geometry, and inspection objective. All measurements are referenced to calibration blocks traceable to national standards.
