  • conformity to quality control requirements for machined wheel centers having a flange, as per TUU 35.2-23365425-640:2009 &TU U 35.2-23365425-643:2009, with test productivity of 20 wheel centers/hour;
  • compliance with quality control requirements for machined locomotive wheels with outer diameter of the rolling circle up to 1350 mm, with test productivity of 10 - 20 wheels/hour, depending on the product size range and specific standard requirements;
  • compliance with quality control requirements for machined freight car wheels of American railways with Ø28"÷ 43" and test productivity of 20 - 25 wheels/hour;
  • test result data communication to a single server of the inspection station, followed by generation of test reports.

Wet fluorescent magnetic particle testing of railway axles

UMPKOS-38 system is designed for magnetic particle inspection of railcar wheels axles during production and after repair.

The system is able to detect both longitudinal and transverse surface flaws (‘B’ sensitivity level as per GOST 21105) in accordance with EN 13261, GOST 31334, RD 32.144-2000, by wet fluorescent magnetic particle technique, using AC combined magnetizing (circular, polar). The system provides 100% inspection of the entire axle surface, except for ends.

This stationary-type system can be either integrated into the workshop process line or operated independently as a stand-alone MT station. Magnetic fluid is made of finely-cleaned degassed water, free from mechanical impurities and fat inclusions.

Test object specifications:

Axles with the below parameters are subject to testing by the system:

  • maximum diameter – 390 mm;
  • minimum diameter of axle journal – ... mm;
  • maximum length – 2500 mm;
  • minimum length – 1500 mm;
  • temperature of test object: +3 °С to +45 °С.

SNK KP-8 automated system for integrated nondestructive testing of railcar wheelsets


  • The System is intended for detection of both surface and inside flaws in freight railcar wheelsets, as well as for measurement of flaw depth and coordinates;
  • Automated inspection is performed on the wheel sets with new machined wheels and repaired axle.


  • The System is used for automated UT, EMAT and ET of railcar wheelsets at repair plants that assemble and examine the newly formed wheelsets;
  • Inspections of the freight railcar wheelsets performed by the System are aimed at confirmatory testing or detection of the existing flaws of in-service or repair origin in the wheelset axle, wheel disk, remand flange, as well as at determining the flaw locations;
  • The System carries out ultrasonic and eddy current inspection of used wheelset components to be further examined or repaired;
  • Testing productivity is no less than ten (10) wheelsets/hour provided that they are smoothly fed to the test position.


The use of automated wheelset inspection System allows increasing the testing productivity and reliability by several times due to simultaneous operation of multiple channels. Not only detected flaws but also all process data are fully recorded by the System during inspections. This helps to avoid NDT inspector’s mistake or negligence, and enables to make a detailed analysis of test results at any time.

Uniscan Luch OS-4 system for automated ultrasonic inspection of railway axles during production


  • Main purpose of the system is to find all kinds of defects in railway axle body according to RD32.144-2000, EN 13261, М101, DSTU 31334 & BN 918275;
  • The system is able to examine machined or semi-machined axles during their production.


  • Ultrasonic testing is automatically performed from the radial surface by immersion technique;
  • Axle to be tested is fully placed into the immersion tank, where it is rotated by central clamping devices, and scanning is performed during linear motion of UT scanner along the axle;
  • The system estimates equivalent sizes and depths of the defects;
  • Axle is inspected along its entire length, except for dead zones in center and bolt holes;
  • Testing facility has its own closed-circuit system of immersion liquid intake, supply and purification.


  • Design of the system is compact and ergonomic;
  • The system can be either integrated into the production line or operated as a stand-alone inspection station;
  • Metal structure test is also provided to check the structure conformity to applicable standards;
  • High productivity of the system is due to absence of multiplexing schemes in eight scanning modules. Time required for inspection of one axle is up to 8 min.

PSh-11 ERW system for nondestructive testing of pipes


  • The system performs a comprehensive automated ultrasonic inspection of welds in longitudinally welded small-diameter pipes during their production;
  • Inner and outer longitudinal defects, as well as residual inside and outside flash are subject to detection in accordance with API Spec 5CT, GOST R 52203-2004, TU 14-3R-27-2000, TU 14-3R-28-2001, TU 14-3R-29-2002, TU 14-3R-31-2005.
