Ultrasonics: Leak Detection

About

Ultrasonic testing is a reliable form of predictive maintenance and quality control which will help technicians detect leaks, worn bearings and other problems before they cause equipment failure or damage. This is one course in a three-part series, where your workers will learn how ultrasound is used in diagnostics and analysis, and will gain an understanding of the components of a typical ultrasound detector.

System leaks affect productivity, product quality and may even cause expensive environmental damage. Ultrasonic technology can detect potential leaking problems before they become costly. This course teaches how to use ultrasonics to detect leaks in pressurized systems, steam traps and valves. Topics include:

-Ultrasonic detector components
-Hand-held unit
-Meter
-Sensitivity and frequency adjustment
-Interchangeable test modules
-Contact and scanning modes
-Heterodyning
-Finding leaks - How leaks happen
-Pressure, vacuum, low pressure and gas leaks
-Effect of turbulence
-Testing procedures
-Threshold and turbulence
-Liquid leak amplifier (LLA)
-Testing procedures
-Steam traps
-Continuous steam traps
-Intermittent drain steam traps
-Testing procedures
-Valves
-White noise vs. hissing sound
-Testing procedures
