In-Service Flange Inspection

The STIX – Flange Scanner is used for a variety of flange coupling inspection applications such as flange face corrosion. Carry one or two phased array probes straight around the flange with the included guiding system while outputting encoded positional feedback to any UT instrument. Magnetic wheels adhere to ferrous surfaces and the articulating frame design allows placement on diameters as small as 7.6 cm (3 in).


Component Identification

Position the dovetail handles along the frame bar for optimal control.

The spring-loaded encoder is fully compatible with all standard instruments.

The magnetic wheels are coated with urethane to reduce the effects of foreign debris obstructing the scanner motion. Two sets of 4 magnetic wheels are included with the system to provide optimal magnetic attraction during scanning operations.

Simplified probe holder carries probe/wedges with ease.

The design of the frame allows scanning flanges as small as 7.6 cm (3 in).

The guides ensure the scanner travels straight around the flange.
