Non Destructive Testing

Non-Destructive Testing is the branch of engineering concerned with all methods of detecting and evaluating flaws in materials. Flaws can affect the serviceability of the material or structure, so NDT is important in guaranteeing safe operation as well as quality control and assessing plant life. The flaws may be cracks or inclusions in welds and castings, or variations in structural properties that can lead to loss of strength or failure in service. The essential feature of NDT is that the test process itself produces no deleterious effects on the material or structure under test. IEQS provide highly skilled, experienced and motivated personnel qualified and certified in accordance with international certification schemes (e.g. PCN (EN 473/ IS0 9712), ANSI CP-189 and SNT-TC 1A) in the conventional techniques that have underpinned the NDT industry from its earliest days.

NDT applications play a role in nearly every stage of the production or life cycle of a component:

  • Equipment integrity analysis
  • Corrosion monitoring of structures and equipment
  • Corrosion damage evaluation
  • Fatigue and creep damage prediction
  • Fitness for service evaluation
  • Product development
  • Screen or sort of incoming materials
  • Monitor, improve or control manufacturing processes
  • Verify proper processing
  • Verify proper assembly
  • Inspect for in-service damage
  • Flaw detection and evaluation
  • Leak detection
  • Location determination
  • Dimensional measurements
  • Structure and microstructure characterization
  • Estimation of physical and mechanical properties
