Thickness Measurement (UTM)：
a. Purpose: Detecting the corrosion or erosion and thinning of piping, tube, equipment, and hull shell.
b. Principle:
c. Application:
1) Measuring the corrosion, erosion and fretting in piping and vessel.
2). Measuring the corrosion in hull shell.
3). Detecting the deterioration of boiler tubes and reactors.
4.) Measure the thickness of oxide/scale build-up on the inside of boiler tubes and helps predict tube life.
Boiler Tube Sound Attenuation Testing：
a. Purpose: Applying UT attenuation measurement is to understand creep and grain coarseness on the material deterioration of tube and equipment in-service。
b. Application:
Boiler tubes, reactors and other materials deteriorate testing.
