A modular, band-mounted crawler for multi-probe PAUT and TOFD inspection.
The SERKO - Base Crawler is a motorized, band-mounted scanning platform designed for circumferential inspection of ferrous and non-ferrous pipes. Its adjustable design lets it travel around a range of pipe diameters while providing a stable, repeatable inspection path. With compatible SERKO probe holder frames, the system supports configurations of up to 10 probes for phased array (PAUT) and TOFD applications.
Features
Cable Management Conduit
A flexible conduit organizes and protects probe cables, hoses, and other service lines as the SERKO travels around the pipe. The conduit keeps lines bundled and controlled throughout the scan, helping prevent tangles and interference with scanner movement.
Couplant Distribution Manifold
Mounted directly to the probe holder frame, the irrigation manifold distributes couplant to the individual probes. Its compact layout keeps couplant lines organized and close to the inspection assembly, helping simplify hose routing around the scanner.
Quick Band Clamping
Large clamp handles make it easy to secure and release the SERKO from the pipe band for fast setup and repositioning.
Guide Band Compatibility
SERKO operates on customer-supplied pipeline guide bands, so it integrates with bands already used for mechanized welding applications. Adjustable band engagement accommodates widths from 80 to 127 mm (3.15 to 5 in.), providing flexibility across a range of existing band systems.
Wide Range of Diameters
SERKO’s adjustable crawler geometry accommodates guide bands from 10 in. OD through flat. Clearly marked diameter settings provide a convenient reference during setup, making it easy to configure the crawler for different pipe sizes.
Spring-Loaded Encoder
Maintains positive contact with the inspection surface to provide consistent feedback of scan position around the pipe.
Phased Array & TOFD Probe Holders
SERKO uses dedicated phased array and TOFD probe holders with multiple adjustment points for probe and wedge positioning. Quick-locking controls simplify setup and repositioning, while dedicated PA and TOFD configurations support multi-technique inspections.
