SPECIALIZED AND CONVENTIONAL NON-DESTRUCTIVE EXAMINATION

The Complex Oil and Gas Structures require reliability in ensuring optimal use for the purpose of which they are constructed. The applicable Integrity assessment employs NDT which involves inspecting, testing or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system.

The range of services under our Integrity Assessment / Inspection includes:

Ultrasonic Testing
Visual Testing
Magnetic Particle Inspection (MPI)
Dye Penetrant Testing
Holidays Inspection & PWHT.
Conventional & Digital Radiography Testing.
Magnetic Flux Leakage (MFL)
Eddy Current Testing, etc.
Guided Wave Long Range Ultrasonic Testing (LRUT).
Phased Array Ultrasonic Time of Flight Diffraction (PAUT/ToFD)

RMS C-Scan Operation

Personnel carrying C-RMS 450 SCAN Services on SPDC pipelines

Phased Array Ultrasonic Testing (PAUT/ TOFD)

Phased array ultrasonic systems utilise multi-element probes, which are individually excited under computer control. By exciting each element in a controlled manner, a focused beam of ultrasound can be generated in seconds and controllable angles. It also focuses on depths and wider coverages from one inspection point to another. Software enables the beam to be steered.

Two and three dimensional views can be generated showing the sizes and locations of any flaws detected.

Time of Flight Diffraction (TOFD)

Time of Flight Diffraction relies on the diffraction of Ultrasonic energies from :corners” and “ends’” of internal structures ( Primary defects) in a component being tested.
