DX Initiatives Phased Array UT Inspection System for Tube to Tubesheet Weld Joints:
kantanPAUT®
Phased array UT has been applied to inspect tube to tubesheet weld joints in heat exchangers used in plants. In order to determine the presence or absence of defects in large numbers of welds, inspectors have had to check more than one million scanned images.
Hitz has developed a system that uses deep learning-based technology to detect abnormalities in images, and automatically determine if there are any defects. This system has substantially reduced the time taken to determine defects and decreased the inspection costs, as well as lessening the work burden of inspectors; it has become a practical way to inspect all of the tube to tubesheet weld joints. We have also created new services, such as in the inspection of competitors’ products and in the field of plant maintenance.
Using PaaS and other cloud services, Hitz will continue to enhance even further the value of our products and services.
