Companies of "OKO Association" group carry out ndt equipment supplies to more than 30 countries


We produce various NDT equipment - from handheld flaw detectorsto complicated automated inspection systems, and together with our test equipment distributors make available all of them to customers in other countries.

The equipment design involves the latest state-of-the-art methods and techniques of nondestructive testing, including ultrasound, phased array, time-of-flight diffraction (ToFD), electromagnetic acoustic (EMA), eddy current, eddy current array, as well as a wide range of industrial scanners of both conventional and custom-specific types. Depending on the application, we select a suitable technique or several NDT techniques which would effectively solve the specified task.

Our flaw detectors are successfully used in the following industrial sectors:

  • railway,
  • power & aerospace,
  • petrochemical & metallurgy,
  • machine building & manufacturing.

The equipment produced by "OKO Association" corporation helps to improve the quality of finish products of our customers, and enhance the safety of their facilities’ infrastructure.



Ndt ultrasonic inspection techniques allow to obtain information about the defects located at a considerable depth in various materials, products and weld joints. As compared to other non-destructive testing methods, ultrasonic flaw detection is featured by significant advantages: high sensitivity to the most hazardous defectslike cracks or incomplete penetration; high productivity; possibility tosupervise the testing directly from operator’s workplacewith no process interruption; low operational costs.Ultrasonic examination is basically applied in a wide range of industries: power, heavy machinery, railway, ship building, chemical sector. Hundreds of thousand metersof steel structure welds, tens of thousands ofpipe joints, boiler units, rail weld joints, as well as the quality of pressurized tank parts, forgings, tubes, rolled plates and otherproductsare annually inspected by means ofultrasonic ndt techniques.

Electromagnetic acoustic (EMA) technique is a combined method of non-destructive testing which is based on three effects of the interaction between magnetic field and test object: magnetostrictive, magnetic and electrodynamic effects. The electrodynamic effect is caused by inducing eddy currents in a conductive material that interact with constant magnetic field, which, in its turn, initiates the material crystal lattice vibrations (whereas elastic acoustic oscillations occur due to mechanical stresses).EMA transducers are capable of generating horizontally & vertically polarized, longitudinal, shear, Lamb and Rayleigh waves. Horizontally polarized shear waves have minimum attenuation, diffraction and metal structure refraction coefficients. EMA technique allows for non-contact ultrasonic examination of material integrity at high temperatures.
