Ultrasonic Thickness Measurement

Ultrasonic Testing (UT) is commonly used for flaw detection in materials. Ultrasound uses the transmission of high-frequency sound waves in a material to detect a discontinuity or to locate changes in material properties.

Ultrasonic Thickness Measurements– is a nondestructive testing (NDT) for hull structures.
It is performed to ensure that global & local vessel strength is retained. Check internal condition and remaining thickness of a vessel. Ascertain all possible areas of concern in terms of thickness measurement and close up requirements for all types of vessels.
AlfaTest’s specialists have extensive experience and qualifications in this area of ​​work.
Principle of Ultrasonic Inspection:
•Ultrasonic waves are introduced into a material where they travel in a straight line and at a constant speed until they encounter a surface.
• At surface interfaces some of the wave energy is reflected and some is transmitted.
• The amount of reflected or transmitted energy can be detected and provides information about the size of the reflector.
• The travel time of the sound can be measured and this provides information on the distance that the sound has traveled.
AlfaTest uses its extensive experience and state-of-the-art UT measuring instruments to solve the most difficult test situations in a reliable and cost-effective manner.
