Overview

Product overview

This scanner family combines battery-powered motion control with ultrasonic inspection equipment for remote corrosion mapping, single-line surveys and weld examination. Magnetic crawlers serve ferrous assets, including inverted surfaces, while chain-driven configurations support ferrous and non-ferrous pipes. Interchangeable attachments allow the systems to be configured for different inspection tasks.

For phased array corrosion mapping, the Aqualock waterbox couples a 7.5MHz 64-element probe through a controlled water column rather than a wedge. Its bubble-removal flow design and foam seal liner support consistent coupling on challenging surfaces. The page specifies 1mm (0.04in) mapping resolution and recordable, auditable data sets. Conventional UT configurations instead use a focused single-crystal probe with local immersion coupling in a gimbaled holder, with twin-crystal options also available.

Weld inspection configurations deploy PAUT and TOFD probes, with integrated instrument capabilities supporting simultaneous TFM, PAUT and TOFD acquisition. Ferrous crawlers accommodate up to six PAUT or TOFD probes, while the non-ferrous chain-link system carries up to four. Applications include circumferential, longitudinal and spiral welds on pipes, vessels, tanks and other structures.

The scanners integrate with Gekko, Mantis and TOPAZ instruments for acquisition, analysis and reporting. Typical work includes corrosion and erosion assessment, hydrogen-related damage detection and inspection of steel, composite and plastic assets. Conventional ultrasonic corrosion mapping can operate at surface temperatures up to 150°C / 302°F; the ferrous crawler requires its medium-temperature add-on kit between 50°C (122°F) and 150°C (302°F).

Key Features

Key capabilities

Remote battery operation

Portable, battery-operated systems provide fully automated, remotely controlled scanning.

Magnetic and chain-driven configurations

Magnetic crawlers support ferrous surfaces, while chain-driven configurations work on ferrous and non-ferrous pipes.

Aqualock coupling

Water-column coupling, bubble-removal flow and a foam seal liner support phased array mapping on challenging surfaces.

Conventional UT mapping

A focused single-crystal probe in a gimbaled holder supports local immersion mapping without requiring phased array-qualified personnel.

Multi-technique weld acquisition

Simultaneous TFM, PAUT and TOFD multi-probe, multigroup configurations collect weld data in a single file.

Corrosion analysis tools

Floating and tracking gates, assisted analysis, wall-loss statistics and report-building tools support corrosion assessment.

Adaptable scanning attachments

Interchangeable bridges, raster arms and probe holders adapt the system to different access and coverage requirements.

Single-line scanning

Probe holders can mount directly to the crawler body for one-axis UT or PAUT corrosion surveys.

Remote inspection accessories

Optical guides, HD cameras and actuated tool posts support alignment, navigation and probe transport.

Operating conditions & limits

Both crawler configurations have an operating environment of -20°C (-4°F) to 50°C (122°F) and are not submersible.
Ferrous crawler performance varies with surface type; heavy payloads may require reduced speeds.
The ferrous crawler requires the medium temperature add-on kit when the inspection surface is between 50°C (122°F) and 150°C (302°F).
Non-ferrous crawler performance varies with surface condition; umbilical and attachments count toward its 9kg (20lb) payload.
The non-ferrous solution specifies a maximum umbilical length of 30m (98.4ft), separately from the general mapping options of up to 60m.
Standard weld tool post arms accept wedge widths from 17.1mm (0.7in) to 57.6mm (2.3in).
Ferrous solution circumferential pipe range is 7cm (2.75in) OD to flat; longitudinal pipe range is 30.5cm (12in) OD to flat.
Non-ferrous solution circumferential pipe range is 15.2cm (6in) to 106.7cm (42in) with the standard overtop link, or 20.3cm (8in) to 106.7cm (42in) with the large overtop link.
