Ultrasonic Thickness Measurement

In the field of industrial Ultrasonic Testing, Ultrasonic Thickness Measurement (UTM) is frequently used to characterize material thickness, integrity, or other physical properties by means of high frequency sound waves. It is widely used for product testing and quality control of steel structures and components.

The Ultrasonic Thickness Measurement used the basic principles of ultrasound as they apply to thickness testing of materials and components. It concentrates on the compressional wave mode (sometimes referred to as longitudinal or “straight beam”) and provides a straight forward way to apply this technique for precise thickness measurements. There are several transducers used and their advantages are presented and demonstrated including straight beam, delay line, and dual element (“pitch-catch”). Variables such as surface conditions, coatings, configuration, couplant and material grain structure are all addressed, and a wide range of applications are included.

NUSATEK is capable of measuring the remaining wall thickness of metal pipes, tanks, structural parts, and pressure vessels that are subject to internal corrosion and erosion that cannot be seen from the outside. Detection of metal loss caused by corrosion, erosion or damage is vital to ensure the continued safety and operation of the inspected structures.

NUSATEK has numerous years of experience in performing Ultrasonic Thickness Measurement and serve almost all engineering industries, such as oil and gas industry, as well as the petrochemical, power generation, and structural contractors sectors. Our fast and reliable services have become well known throughout the sectors.

The advantages offered by Ultrasonic Thickness Measurement are:

  • fast, reliable, and versatile,
  • Probe requires access to only one side of the test piece.
  • Portable equipment allows for on-site inspection and results are instant
  • Can be easily deployed, does not require laboratory conditions
  • No cutting or sectioning required
