Visual inspection and routine maintenance are the keys to ensuring the longevity and safe operation of steel vacuum tanks. When the thickness of a steel tank is in doubt, ultrasonic testing can provide a definitive measurement of the remaining steel, at a given point, or across a broader spectrum of locations.An electronic ultrasonic thickness gauge can test the wall thickness of materials including steel and plastic, and determine the effects of corrosion or erosion on any tank structure where access is limited to the outside.The technology works by sending a pulse of high-frequency soundwaves into a solid material to analyze
