Ultrasonic testing is the most effective, non-destructive method of testing. It allows you to determine the thickness of almost all materials. This method is particularly useful in hard to reach applications like piping, ship bulkheads, large storage tanks, etc. UTT can penetrate up to 20″, which is deeper than other methods such as liquid penetrants. Some commonly tested materials are carbon steel, stainless steel, aluminum, and polycarbonates.
