Wall Thickness Measurement
The use of ultrasonic testing to measure the remaining wall thickness in vessels, piping, and other components to detect corrosion or erosion. Regular thickness measurements track the rate of wall loss and determine when components must be retired from service. Comparison of actual thickness to minimum required thickness (based on design and corrosion allowance) determines fitness for continued operation. Ultrasonic thickness measurement is fast, non-destructive, and cost-effective.
