Visual Examination (VT)

VAIC uses the Visual inspection which is the first and most common inspection technique used in the oil and gas industry. Corrosion, cracks, leaks, and defects can all be identified by close visual inspection. Visual inspections are relatively fast and inexpensive compared to other NDT methods as well. However, there’s a limit to what the eye can see, even with a borescope. Other NDT methods are needed to identify internal flaws before they reach the surface.
