The ScanmapVS system utilises the proven reliability of the Scorpion wall crawler with an added transverse scanner fitted to the front end. The transverse scanner covers a 130 mm wide strip at a speed of 700 mm per second and with a forward crawler speed of 900mm per minute.

Using a single 10mm diameter short pulse 5MHz transducer mounted in a water column the ScanmapVS is effectively a remote access immersion system. Sampling every 6mm in the direction of travel the ScanmapVS provides rapid inspection whilst achieving complete UT coverage.

The ScanmapVS

By combining an existing high speed ultrasonic pulser/receiver card and ultrasonic imaging software with the Scorpion scanner, Silverwing’s latest product, the ScanmapVS benefits from proven technology at the outset. Stored data can be viewed as either A-scan, B-scan or C-scan images.

The adjustable scanning head allows inspection of small vessels and pipes with a minimum diameter of 1m. The ScanmapVS now makes it possible to ultrasonically scan a 130mm wide strip vertically up tank walls and columns or circumferentially around vessels and pipework covering approximately 7 square meters per hour. Meet or even exceed the requirements of the relevant inspection standards without the need for costly rope access or scaffolding.
