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

TYPICAL APPLICATIONS

Typical Applications of UT

Ultrasonic Testing is commonly applied to inspect critical components and structures across a wide range of industries.

  • Welded joints
  • Storage tanks
  • Pressure vessels
  • Piping systems
  • Steel structures
  • Offshore structures
  • Forgings and castings
  • Marine assets
  • Heavy lifting equipment
  • Process equipment

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

  1. Surface must be accessible to transmit ultrasound
  2. Usually a couplant (gel or oil) is needed to enable interference-free transfer of the ultrasound
  3. Objects that have a rough surface or are very small, thin or not homogenous are difficult to inspect
  4. Cast iron and other coarse grained materials are difficult to inspect due to low sound transmission and high signal noise
  5. Linear flaws oriented parallel to the direction of the sound beam may go undetected
  6. Reference standards are required for equipment calibration and for the characterization of flaws
