Non-Destructive Testing or Evaluation

Non-Destructive Testing or Evaluation (NDT/NDE) involves the inspection of plant equipment, machines, machine parts and components to identify surface or internal defects and determine condition and fitness for use using techniques that do not impair the items' functionality.

NDT Methods

Common methods used in NDT testing and inspection are:

  • Visual examination

  • Leak detection

  • Radiography (x-rays)

  • Ultrasonic thickness gauging

  • Magnetic particle inspection

  • Hydrostatic testing

  • Ultrasonic flaw detection and sizing

  • Hardness testing

  • Liquid penetrant

    •
