NDT INSPECTION

KIT- SIS Division has a pool of fully certified inspectors qualified to handle the NDT inspections. They are all trained and certified ASNT NDT Level II or Level III, and conduct the inspections as per the official international standards.

Non-destructive testing are techniques that can be used in inspecting materials and equipment without damage to them. It is implemented at the fabrication, construction, assembly and maintenance stage of the life of the products. Its objective is to verify the quality of the tools´ materials and enable products control, contributing to guarantee the quality, reduce the costs and increase the inspection reliability. It is widely used in the following industries:

  • Petroleum
  • Petrochemical
  • Chemical
  • Aeronautical
  • Aerospace
  • Steel
  • Shipbuilding
  • Electromechanical
  • Pulp and paper Etc

NDT contribute to the quality of goods and services, reduction of costs, life and environment preservation as well as being a competitive differentiator for companies that use it.

Magnetic particular examination (MPE), Dye penetrant test, radiography, ultrasonic test. Several types of NDT exist. The most common ones are gathered here below:

  • Visual Inspection (VI)
  • Dye Penetrant Inspection (DPI)
  • Electro-Magnetic Testing:
  • Eddy Current Testing (ECT)
  • Magnetic Flux Leakage (MFL)
  • Electro-Magnetic Induction Inspection (EMI)
  • Magnetic Particles Inspection (MPI)
  • Ultrasonic Testing (UT):
  • Internal Rotating Inspection System (IRIS)
  • Time of Flight Diffraction (TOFD)
  • Phased Array Ultrasonic Testing (PAUT)

Depending on the parameters (shape, material, use, location, etc.) of the item to be inspected, you may want to check more or less deeply the existence of potential defects. The size of the “maximum allowed” defect will also lead you towards one method or another.

Some tests require a very careful handling, especially the radiographic testing with a radioactive source. Many parameters have to be taken into consideration for complex cases, but usually, the choice of the NDT method is straight forward. If needed, it can be discussed together with KIT- SIS Division inspectors.

NDT is most commonly used for all kind of forged, welded or “stressed” items. It can either be simple plate (gusset, pad-eye), or a piece itself (shackle, hook), or an equipment welded on a deck or somewhere else (winch, davit).

The NDT target is to confirm the integrity of the concerned equipment without touching it directly. This also means without causing any damage; it will remain identical to its pre-inspection status.
