Types Of Pressure Vessel Inspection

Careful visual examination is the most important and the most universally accepted method of inspection. However, this does require entry to the vessel, which itself presents risks to inspection personnel, and also requires a period out-of-service which impacts productivity. By using advanced NDT methods the requirement for internal visual examination can be reduced, or potentially removed. These NDT methods include:

  • Corrosion Mapping
  • Ultrasonic thickness measurement and flaw detection
  • MFL Screening
  • Magnetic-particle examination for cracks and other elongated discontinuities
