Visual Inspection (VT) relies upon the detection of surface imperfections using the eye or remotely using borescopes or videoscopes. Normally applied without the use of any additional equipment, VT can be improved by using aids such as a magnifying glass and white light to improve its effectiveness and scope.

Visual inspection can be used for internal and external surface inspection of a variety of equipment types, including 

  • Piping
  • Storage Tanks
  • Boilers
  • Vessels
  • Welds

It is also one of the most reliable techniques. A well-trained inspector can detect most signs of damage.

We provide the following services with this method:

Structural Steel Inspection.

Welding Inspection.

In-Service Inspection.


Remote Visual Inspection (Borescope):

In additional to traditional visual testing, SGEIPL offers borescope and remote video testing services, which are video tools that can be used to visually inspect asset interiors and those in hard-to-access locations.

Industrial videoscopes are commonly used for visual inspection of inner areas of various infrastructure equipment as well as industrial products.

Heat Exchanger inner wall flaws are visually inspected through a videoscope, it is possible to assess significance of the damage more precisely. As such, combination use of NDT equipment and industrial videoscopes enables more reliable inspections.

RVI can be used to examine equipment as diverse as boilers, steam and gas turbines, generators, heat exchanger and condensers, tanks and vessel, rotating equipment, welds, and piping systems for flaws and corrosion. Used with extraction tools, RVI also has applications in foreign object search and retrieval.
