Thickness measurement of metal

Ultrasonic metal thickness measurement is used to determine the actual thickness of metal in metal structures that are not accessible or difficult to measure with a tool. In addition, this method allows you to determine the dimensions of equipment parts without dismantling them. For example, pipeline elements, shafts, studs, etc. 

How is metal thickness measurement performed? 

During the survey, measurements are taken at many points to identify possible areas of metal thinning and obtain a representative sample. One-way access to the object is enough to start the study. 

For more accurate results of the study, further processing and analysis of the information received is necessary. Directly on the spot, our specialist can only announce the approximate results of the control. 

Is it possible to carry out thickness measurement of parts of complex geometric shape? 

Yes, for such thickness measurements, special compact transducers are used, which ensure tight contact between the transducer and the test object. 

Information required for thickness measurement 

To perform ultrasonic thickness measurement of metal, the following information about the test object is required: 

1. Name of the object of control (diagram, drawing or photograph); 

2. Steel grade; 

3. Number of similar products. 

4. Number of points (measurements) – if the volume is known (laid down by the project, defined in the prescription, etc.) 

5. Presence/absence of elevation marks.
