Ultrasonic Testing is a type of Non-Destructive Testing (NDT) that uses high-frequency sound waves to inspect materials for internal defects, measure thickness, and evaluate structural integrity without damaging the object. It’s widely used in oil & gas, petrochemical, industrial, manufacturing, infrastructure, and construction sectors. Typical applications include:
- Detecting internal flaws such as cracks, voids, and inclusions.
- Thickness measurements on pipes, vessels, and structural components.
- Weld inspection and corrosion scanning in pressure equipment and pipelines.
- Advanced UT methods include Phased Array (PAUT) and Time of Flight Diffraction (ToFD) for higher resolution and sizing capability.
Ultrasonic Testing helps ensure safety, compliance with industry standards (e.g., API, ASME), and operational reliability without interrupting service.
