Companies of "OKO Association" group supply NDT equipment to more than 40 countries

We produce various NDT instruments – from handheld flaw detectors to complex automated inspection systems, which are available worldwide through our network of distributors. Besides the sales, we provide post-sale and warranty services for all our products.

Our equipment utilises a variety of state-of-the-art methods and techniques for non-destructive 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 other conventional and custom approaches. We are focused on identifying the appropriate technique or combination of techniques to meet your specific needs.

Our flaw detectors are commonly used in the following industries:

  • railway,
  • energy & aerospace,
  • petrochemical & metallurgy,
  • machinery

The equipment produced by "OKO Association" improves the quality of our customers’ finished products and enhances the safety of their infrastructure.

NDT ultrasonic inspection techniques allow to detect the defects located at a considerable depth in various materials, products, and weld joints. Compared to other non-destructive testing methods, ultrasonic flaw detection has significant advantages: a high sensitivity to the most hazardous defects like cracks or incomplete penetration; high capacity; and the ability to supervise the testing directly from an operator’s workplace with no process interruption – all at low operational cost. Ultrasonic examination is applied in a wide range of industries: energy, heavy machinery, railway, ship building, and the chemical sector. Hundreds of thousands of meters of structural welds, tens of thousands of pipe joints, boiler units, rail weld joints, as well as the quality of pressurised tank parts, forgings, tubes, rolled plates and other products are annually inspected by means of ultrasonic NDT techniques.

The electromagnetic acoustic (EMA) technique is a combined method of non-destructive testing based on three effects of interaction between magnetic fields and the 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 crystal-lattice vibrations (whereas elastic acoustic oscillations occur due to mechanical stresses). EMA transducers are capable of generating horizontally & vertically polarised, longitudinal, shear, Lamb, and Rayleigh waves. Horizontally polarised shear waves have minimum attenuation, diffraction, and metal structure refraction coefficients. The EMA technique allows for non-contact ultrasonic examination of material homogeneity at high temperatures.
