Visual Survey

NDT Global Services offer visual survey and inspection, applications include primary processing inspection and secondary finishing process inspection.

Visual inspection can be used for internal and external surface inspection of a variety of equipment types, including pipelines, storage tanks, pressure vessels, and other equipment. Advantages of visual inspection are that it is a cost effective form of inspection due to the reduced equipment needed, and it can be used as a pre-inspection method to determine which areas require further NDT inspection.

NDT Global Services also have trained API 570 visual inspectors, capable of maintaining the mechanical integrity of piping systems.

Visual inspection examinations of surface defects include:

  • Fatigue cracks
  • Creep failure
  • Corrosion
  • Erosion
  • Abrasion
  • Adhesive wear
  • Mechanical damage
  • Wear and tear
  • Distortion
  • Poor workmanship
