Solution-based Manual Ultrasonic Testing Scanners
Modular manual ultrasonic scanners provide encoded probe positioning for corrosion mapping and weld inspection across small-bore, high-temperature, flange and nozzle applications.

Product overview
This family of manual and semi-automated ultrasonic scanners positions probes for corrosion mapping and weld integrity assessment. The modular configurations support PAUT, TFM and TOFD inspection applications, with dedicated arrangements for small-bore tubing, carbon steel, non-ferrous materials, hot assets, flange faces and nozzles.
The scanners provide positional encoding as probes move over the inspection surface. Magnetic-wheel configurations travel on ferrous materials, while chain systems secure probes around ferrous and non-ferrous components. The fixed-frame XY corrosion scanner encodes both scan and index motion and supports localized immersion using the Aquablock waterbox, linear array probes with a 0L wedge, or dual linear array probes.
Application-specific mechanics address access and geometry constraints. The small-bore scanner uses adjustable links and requires 11mm radial clearance for the scanner alone, excluding transducers and wedges. The high-temperature configuration supports on-stream inspection up to 350°C (662°F), while the nozzle scanner combines probe-position and skew encoding for constrained nozzle weld access.
Typical work includes vessel and pipework corrosion surveys, fabrication and in-service weld inspection, flange face corrosion detection, and nozzle weld assessment. Entry-level configurations offer encoded PA or TOFD probe positioning on ferrous surfaces, with modular conversion to a non-ferrous chain scanner; a separate universal-clamp encoder option supports one-handed operation in restricted spaces.
Key capabilities
Application-specific modularity
Dedicated scanner configurations address corrosion mapping, welds, flange faces, nozzles and restricted-access inspections.
Low-profile small-bore scanning
Snap-together links adapt the small-bore scanner to different pipe diameters with single- or dual-probe configurations.
Encoded XY mapping
The lightweight fixed-frame corrosion scanner provides scan-axis and index-axis encoding for large-surface mapping.
Convertible weld scanning
The long-seam scanner converts between longitudinal and circumferential inspection using a pivoting frame bar.
Non-ferrous chain deployment
Quick links secure the chain scanner on ferrous and non-ferrous surfaces without magnetic attachment.
High-temperature operation
A dedicated magnetic scanner supports online weld inspection up to 350°C (662°F) with heat-resistant cable management and wheels.
Flange face coverage
Tapered-neck scanning provides 100% sealing face coverage using an adapted weld inspection scanner.
Encoded nozzle positioning
The nozzle configuration combines an encoded skew probe holder with a leadscrew positioning system and Y-axis feedback.
Modular entry-level inspection
Entry-level weld scanners include positional encoding, magnetic wheels and adjustable slip-joint probe holders.
Universal-clamp encoder option
A compact encoder scanner holds a range of probe and wedge combinations and supports one-handed operation.
