Ultrasonic Testing (UT)
MME Group delivers independent inspection, material testing and corrosion prevention through in-house experts.
What is Ultrasonic Testing?
Insight into material integrity without causing damage
Ultrasonic Testing (UT) is a volumetric Non-Destructive Testing method used to detect internal flaws, discontinuities and wall thickness variations without damaging the material. Using high-frequency sound waves, our inspectors provide accurate information about the condition of critical assets, helping improve safety, support compliance and prevent unexpected failures.
Benefits
- Detection of internal defects without material damage
- Accurate wall thickness measurements for integrity assessments
- Improved asset reliability through informed maintenance decisions

Performance overview
Strengths and limitations of ultrasonic testing
Strenghts
- High penetrating power
- High sensitivity
- Usually only one surface needs to be accessible
- Insight in size, orientation, shape and nature of defects
- Non-hazardous to operations or nearby personnel
- Portable equipment
- Can be used in automated setup
- Immediate test results
Limitations
- Surface must be accessible to transmit ultrasound
- Usually a couplant (gel or oil) is needed to enable interference-free transfer of the ultrasound
- Objects that have a rough surface or are very small, thin or not homogenous are difficult to inspect
- Cast iron and other coarse grained materials are difficult to inspect due to low sound transmission and high signal noise
- Linear flaws oriented parallel to the direction of the sound beam may go undetected
- Reference standards are required for equipment calibration and for the characterization of flaws
