On October 1-4, 2023 OKOndt GROUP attended Railway Interchange 2023 - the largest North American railway event. This time the exhibition took place in Indianapolis, Indiana, USA (Indiana Convention Center) and brought together over 700 exhibitors and more than 8, 000 visitors who are the major influencers in the industry. Thank you to everyone who was with us at the RI 2023!

Ultrasonic calibration blocks

  • Application

V2 Calibration Block is designed for verification of the ultrasonic flaw detectors used in the course of welded joints quality control by the UT method. It is DSTU 4002-2000 (ISO 7963, В.S.2704) compliant.

V2 Calibration Block allows:

  • to calibrate the sweep of the flaw detector by the ultrasonic wave velocity for the straight beam piezoelectric transducers
  • to calibrate the sweep of the flaw detector by the ultrasonic wave velocity for the angle beam piezoelectric transducers
  • to set a conditional level of sensitivity of the UT flaw detectors with the straight and angle beam transducers
  • to determine the probe index and X-value of the angle beam transducers
  • to determine the UT wave entry angle in steel.

  • Technical data

  • velocity of the ultrasonic longitudinal waves in the Block material at a frequency of 5.0 MHz and a temperature of (20±5)ºC is (5920±30) m/s
  • velocity of the ultrasonic shear waves in the Block material at a frequency of 5.0 MHz and a temperature of (20±5)ºC is (3255±15) m/s
  • geometrical dimensions of the Block correspond to DSTU 4002-2000 (ISO 7963, B. S. 2704).
