Laser Based Online Monitoring of Eccentricity and Wall Thickness of Seamless Tube

M. Klein, T. Bodenhamer, E. Raita, A. Kamshilin

Monitoring the wall thickness during the manufacture of seamless steel tubes and cast-iron pipe is critical in meeting specifications and minimizing scrap. Laser based ultrasonic inspection system based on laser ultrasonic receiver by Lasson Technologies Inc., USA, and represented in Scandinavia, Russia, and CIS by Optoinspection Ltd, Finland, demonstrates the ability to perform measurements at high forming temperatures (up to 1,200 degrees C) and at high speeds (up to 5 meters per second). It allows control of critical parameters during the production process, thereby providing much more immediate and effective feedback to the machine operator.
