Inspection Services NDT

Our NDT Inspectors are fully certified ASNT Level II in VT, MPI, UT, PT & RT. Our inspection procedures follow a strict standard that meet API and/or DS-1 CAT 1-5 standards. We deploy a world class technology and expertise in providing services tailored to fit the requirments of our clients in any sector of the economy.

1. Magnetic Particle Inspection

Magnetic Particle Inspection is used to detect surface breaking flaws for ferrous materials. Electromagnet or Permanent Magnets are used during this inspection technique.

2. Dye penetrant inspection

Dye Penetrant Inspection is an inspection method used to locate surface breaking defects in non-porous materials. Consideration that needs to be given in selecting the technique of this inspection includes:

  • The type of discontinuity sought;
  • The expected size of the discontinuity;
  • The surface finish on the material.
Care and consideration must also be given to the compatibility of the chemicals used for the inspection and the material being inspected so that there are no permanent degradation to the material.

3. Automatic Ultrasonic Testing

Ultrasonic Inspection technique transmits sound waves into materials and then analyses the reflection of these sound waves. This determines whether they are reflected off the back wall of the material being inspected or off flaws within the material. Using the most up to date equipment and techniques that we deploy, Ultrasonic Inspection is used to carry out thickness measurement and corrosion surveys.

4. Radiography Inspection testing

Radiographic Testing is a Non-Destructive Examination (NDE) technique that involves the use of either x-rays or gamma rays to view the internal structure of a component. It is often used to inspect machinery, such as pressure vessels and valves, to detect for flaws and also used to inspect weld repairs. Our Real-time radiography (RTR) technology is a form of digital radiography that occurs in real time by emitting radiation through an object. These rays then interact with either a special phosphor screen or flat panel detector containing micro-electronic sensors. The interaction between the panel and the radiation creates a digital image that can be viewed and analyzed in real time.

5. Electromagnetic inspection (Eddy current testing)

Eddy current inspection is one of several NDT methods that uses the principle of electromagnetism as the basis for conducting examinations. We deploy a computer-based test instruments and test coils to meet our client's needs for their services on ferrous and non-ferrous metals. Eddy currents can be used for Crack detection; Material thickness measurements; Coating thickness measurements; Conductivity measurements for:

  • Material identification;
  • Heat damage detection;
  • Case depth determination;
  • Heat treatment monitoring

6. Visual Inspection Test

Visual Testing is a Non-destructive Testing technique commonly used to inspect and examine a variety of visible flaws such as cracks, corrosion and contamination. Our remote testing techniques are used where distance, angle of view and limited lighting may impair direct visual examination or where access is limited by time or atmospheric hazards. Visual testing is inherent in most of the other test methods. Technologies we use in this type of testing include rigid or flexible boroscopes, videoscopes, push cameras, pan/tilt/zoom cameras and robotic crawlers. Our testing technique can also be used as a predictive maintenance or regularly scheduled maintenance tool to assess the health, stability and operability of fixed and portable assets.

7. Hardness test

Hardness testing makes it possible to determine material characteristics such as strenght, ductility and wear resistance. Our indenter tool makes it possible to determine the hardness by measuring the depth of penetration or by measuring the size of the impression left by the tool.
