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.

Visual inspection examinations of surface defects include:
- Fatigue cracks
- Creep failure
- Adhesive wear
- Mechanical damage
