Available to rent/hire from Ashtead Technology, the Silverwing Scorpion Ultrasonic Crawler.
The Scorpion is a rugged remote access ultrasonic (UT) crawler designed for effective ultrasonic inspection on ferro-magnetic structures such as storage tanks, vessels and offshore installations without the need for costly scaffolding or rope access associated with UT thickness gauging.
When combined with the UT Lite the Scorpion continuously records thickness measurements as it moves over the inspection surface. The recorded thickness information is presented in the software as an A-scan trace, a digital thickness measurement and a B-scan profile.
The Scorpion DCP/A remote access crawlers use a unique “Dry Coupled” ultrasonic wheel probe eliminating the need for traditional couplant. This allows the crawler to travel vertically, horizontally or even inverted whilst still fully functional, and removes the need for constant water supply.
The wheel probe performs like a standard twin ultrasonic transducer, and can measure thickness from 2.5 mm to over 100 mm, including through paint. In front of the wheel probe is a neodymium magnet which maintains constant probe pressure whilst travelling on the inspection surface.
