ULTRASONIC THICKNESS MEASUREMENT (UTM)

Ultrasonic thickness measurement (UTM) is commonly used and the method can be applied to a wide range of structures and components that includes ship hulls, piping, pressure vessels and structural steel. 

Detection of metal loss caused by corrosion, erosion or damage is vital to ensure the continued safety and operation of the inspected item/structure.  It can also help determine if repair work or replacement is needed or if the item/structure should be retired. Ultrasonic thickness measurement data gives customers the necessary information required to determine if the tested item has the adequate metal thickness for which it was designed.
