2016/11/8 · Ultrasonic testing (UT) is the most widespread and preferred method to determine tube thickness among other issues. Most of the known boiler tube failure mechanisms can be generally suspected, although not specifically identified, via UT. It requires minimal training and typically is fast, inexpensive, and reliable.

In order to calculate this reduction we must take into account the variances between the Tube OD, Tube Wall Thickness and Tube Sheet Hole Diameter. We must also consider the differing types of materials being used for both Tubes and Tube Sheets, however as a general rule, percentage wall reduction ranges between 4% – 10%.
