Inuktun’s newly released MaggUT™ has plenty of potential for several applications, but tank inspections will likely become this little guy’s forte.
Introduced in July 2015, MaggUT™ is a magnetic crawler with UT scanning capability based on Inuktun’s proven Versatrax 100 MicroMag™ platform. The new system is specifically designed to incorporate industry standard ultrasonic probes and flaw detectors from Olympus.
To test its chops, Inuktun staff teamed up with inspection staff from a local pulp and paper mill in Nanaimo, British Columbia. The mill’s tanks contain chemicals and acids that are used in the pulp making process, and a leak would pose an environmental risk as well as risk to human life. It is important to note that because of the mill’s strict inspection standards, there has never been a leak at the site since it was built in the 1950s.
However, aging infrastructure requires more vigilant inspection.
For tanks and pressure vessels, it is critical to obtain accurate thickness readings to ensure integrity of the structure. This includes welds, plates, flanges, and other components where corrosion and physical flaws may deteriorate integrity.
API 653 tank inspection standards define the requirements for inspecting in-service tanks, including minimum thickness for tank floors and walls and visual verification of services.
Weighing less than 15 pounds and available with up to 100 feet of control, coax and couplant hose cables, the MaggUT™ is easily deployed, eliminating the need to build expensive scaffolding. The vehicle can be used to perform A and B scans on a variety of flat and curved surfaces, and intuitive computerized controls allow for precise maneuvering and positioning of the crawler.
The trial concluded successfully, opening up a new storage tank inspection option for industries where flaw detection, increased visual inspection, and thickness scans are top priority.
