Chimney Ultrasonic thickness Gauging Inservice Inspection by Trinity NDTians
Chimney Ultrasonic thickness Gauing Inservice Inspection by Trinity NDT ians Ultrasonic thickness gauging(UTG) is one of the most reliable method of finding the wall thickness measurement of chimneys in process plants. Usually chimney walls are subjected to severe corrosion due to the passage of exhaust gases and other environmental factors. Presently there are large number of portable Ultrasonic thickness gauging equipment are available to a diversity of thickness gauging applications . Normally for this type of application accuracy of around + or - 0.1mm is practically advisable. As the surfaces of the Chimneys are usually will be having thick scaling and unevenness, it may not be suitable to carryout direct Ultrasonic thickness gauging and may require to be grinded /polished with emery for better even surface to get consistent and reliable thickness measurement results before thickness measurement.Calibrated Ultrasonic thickness gauging shall be u...
