IQI provides Ultrasonic TOFD to inspect welds of process vessel and piping. TOFD is reliable and fast advanced. In a TOFD system, a pair of probes sit on opposite sides of a weld. One of the probes emits ultrasonic pulse that is picked by the probe on the other side.
In undamaged pipe, the signals picked up by the receiver probe are from two waves, one that travels along the surface and the other that reflects off the far wall. When a crack Is present, there is a diffraction of the ultrasonic wave from the tip(s) of the crack. Using the measured time of flight of the pulse,the depth of a crack tip can be calculated automatically by simple trigonometry. This method is even more reliable than Radiographic testing of a weld.
The automated corrosion mapping.Automated Corrosion mapping utilizes one or more ultrasonic straight beam probes using dual X & Y axis scanner over a pipe or pressure vessel to map the thickness. These measurements are converted into colour coded images with digital wall thickness profile.
C scan can also be utilized to detect HIC, SWC, corrosion, pitting, blisters etc. Currently we have the capability to scan high temperature corrosion mapping up to 400 degree Celsius.

Electro magnetic Acoustic Transducer (EMAT) is a transducer for non-contact sound generation and reception using electro magnetic mechanisms. EMAT method does not require contact or couplant, because the sound is directly generated with in the material adjacent to the transducer.
Due to this couplant free feature, EMAT is particularly useful for automated inspection and hot, cold, clean, or dry environments. EMAT is an ideal transducer to generate Shear Horizontal (SH) bulk wave mode, Surface Wave, Lamb Waves and all sorts of other guided-wave modes in metallic and/or ferromagnetic materials. As an emerging (UT) technique, EMAT can be used for thickness measurement, flaw detection and material property characterization. After decades of research and development, EMAT has found its applications in many industries such as primary metal manufacturing and processing, automotive, railroad, pipeline, boilers.

ET is working on the principle of induced current called Eddy Current. When a current carrying coil brought into a specimen, Indicators reveal discontinuities that alter the patch of the induced currents.
IQI Provides Remote field Eddy current testing unlike the impedance plane analysis form of common eddy current testing (ET). The remote field eddy current (RFET) technique is a through transmission effect that reduces problems such as lift-off normally associated with ET. In the inspection of steam generator (SG) tubes, the real issues to detect the minute cracks growing up from the outside. However, using Edit is considered infeasible to accurately find them from the inside because of the limitations of penetration of eddy currents. This describes a finite element approach to the solution of time harmonic electromagnetic fields for the RFET technique based on a magnetic vector potential and an electric scalar potential. A comparison is made of experimental and finite element predictions of electromagnetic phenomena under the inspection of non-magnetic tubes. For the cracks outside demanding high sensitive and precise measurements in the SG tube inspection, numerical results are given for parameters to design a RFET probe.

In-service inspections are more formally controlled by statutory requirements than other types of inspections. The ‘duty of care’ requirements are placed on plant owners, operators, and inspectors. All equipment should pass safety and compliance standards, regulations, and guidelines. Mechanical equipment can break down at any time when it is in service, which can lead to delays in production, increasing costs and liability. To prevent these situations from occurring, it is important to schedule inspections regularly.
This will ensure the equipment has been installed, operated, and maintained properly under the watch of a qualified inspector.
