The Research and Manufacturing company "Mashproject" sent the VID-345 Flaw Detector and 281M Crack Depth Meter to PAO "Gazprom" company to test them and receive data for its research work.

The VID-345 flaw detector was used to check the pipeline section with no preliminary surface treatment. As a result, the NDT inspectors noted the following advantages of the device:

  1. The case with the sewn-in magnets and a cuff for attaching the equipment to the arm kept both inspectors' hands free, which allowed them to place the device vertically to the side surface of the pipe.
  2. Magnetic anomalies have a small effect on VID-345 performance. The defect depth was measured with high reliability.
  3. The device can operate in low-temperature environments. One single battery load was enough for full shift time (8 hours) with the display turned on. The temperature was around -20 °C...-25 °C (4 - 13 degrees below Fahrenheit).

According to the experts that used the detector, there is a potential in what has to do with monitoring the change in the air gap (thickness of the coating) during insulation reapplication process.

As to the 281M crack depth meter, further research is required, since the flaws found at the facilities under monitoring were little this time.
