Our NDT Services

Comprehensive conventional non-destructive testing methods tailored to your industry requirements

Welder performing ultrasonic testing on pipeline weld

Ultrasonic Testing (UT)

Conventional ultrasonic testing using high-frequency sound waves to detect internal flaws, measure wall thickness, and evaluate weld integrity in pipelines, pressure vessels, and structural components.

  • Weld inspection & flaw detection
  • Wall thickness measurement
  • Lamination detection
  • Corrosion mapping
Oil refinery facility for radiographic testing

Radiographic Testing (RT)

Conventional radiographic testing using X-ray and gamma ray sources to produce images of internal structures, revealing defects such as porosity, slag, and incomplete fusion in welds.
