Ultrasonic thickness measurement (UTM) is a non-destructive testing method used to inspect the metal thickness of ship hulls, piping, and structural steel.
Thickness measuring is an essential part of steel hull inspections to monitor corrosion, erosion and damage. 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, decks, or any other metal parts.
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
Dye Penetrant Inspection (DPI) is widely used to detect hull surface and welding lines breaking flaws.
This non-destructive testing technique, also known as liquid penetrant inspection (LPI), is a cost-effective method used to locate surface-breaking flaws such as cracks, porosity, laps, seams, and other surface discontinuities. Dye penetrant inspection can be applied to both ferrous and non-ferrous materials and all non-porous materials (metals, or aluminum).
The method is also useful for testing on-site as it is portable, and when applying certain techniques such as visible color contrast there is no need for additional resources such as electricity or water. This makes it highly convenient for inspecting surface discontinuities
In addition to the hull thickness measurement, we have the expertise to identify and spot the rusted and corroded areas and the reason for corrosion providing the ideal solution for the rust of corrosion found.
