Ultrasonic Thickness Gauging (UTG) – Accurate & Reliable Non-Destructive Measurement

At InspecNDT, we provide cutting-edge Ultrasonic Thickness Gauging (UTG) solutions to help industries maintain structural integrity, prevent failures, and ensure compliance with safety standards.

  • High-Precision Measurement – Accurately determines material thickness using ultrasonic waves.
  • Non-Destructive Testing (NDT) – Preserves the integrity of components without damage.
  • Versatile Applications – Ideal for metals, plastics, composites, and coatings.

Uses

Ultrasonic Thickness Gauging is a crucial preventive maintenance tool for industries that require precise monitoring of corrosion, erosion, and material thinning. It helps detect thickness variations in pipelines, tanks, and structu components.

  • Monitors corrosion and erosion in critical infrastructure.
  • Measures material thickness without cutting or damaging components.
  • Works effectively on metals, plastics, ceramics, and composites.

Applications

UTG is widely used in industries like oil & gas, aerospace, marine, power plants, and manufacturing to detect material degradation before failure occurs.

  • Evaluates wall thickness in pipes, tanks, and pressure vessels.
  • Used in aerospace for aircraft skin and structural testing.
  • Ensures quality control in automotive and shipbuilding industries.

Limitations

Rough, dirty, or coated surfaces may require preparation

Precise probe positioning is required for accurate measurement.

Cannot detect subsurface defects, only measures thickness.

Calibration and proper probe coupling require skilled operators.

May not work effectively on extremely thick materials.

Requires a gel or liquid for effective sound wave transmission.

Contact us
1.How does Ultrasonic Thickness Gauging work?

UTG sends high-frequency sound waves into a material and measures the time it takes for the waves to reflect back, calculating the thickness.

2.What materials can be tested using UTG?

UTG is effective for metals, plastics, composites, ceramics, and coatings.

3.Can UTG detect internal defects?

No, standard UTG only measures thickness. For internal flaw detection, Phased Array Ultrasonic Testing (PAUT) or Radiographic Testing (RT) is used.

4. Does UTG require surface preparation?

Yes, coatings, rust, or rough surfaces can affect accuracy, so proper cleaning or gel application is necessary.

5.Can UTG be performed on-site?

Yes, UTG is a portable and widely used field-testing method for real-time monitoring.

6.Is Ultrasonic Thickness Gauging expensive?

No, compared to Radiographic Testing (RT), UTG is a cost-effective solution for thickness measurement.
