Technology

KMD-03
KMD-03 is a sub-contact analogue of KMD-01M and is intended for diagnostics of ground pipelines, tanks and other metal structures. The operating principle of the device is based on measuring the magnetic field with fourteen linearly located magnetic field sensors. Such configuration of sensors allows to get an area picture of magnetic induction lines distribution and localize defects with high accuracy.

System KMD-03:

  1. Is completely passive - they do not emit electromagnetic or other radiation and have no effect on the object under investigation;
  2. Does not require changing the pumping mode of the product
  3. Does not require pipeline preparation for inspection.


Technology

In the course of diagnostics, the operator moves the complex vertically along the entire circumference of the pipeline, receiving a map of the magnetization of the pipe, corresponding to the capture strip of the device. At detection of areas of change of a magnetic field, the expert allocates them with a marker directly on a body of the pipeline. Further, the selected areas are carefully examined by standard methods of nondestructive testing to determine the type of defect detected and the exact wall thickness of the pipeline in this place. Based on the results of the work, a report on the technical condition of the pipeline is prepared.
