Dimensioning and inspection solutions for optimal pipe welding results


Tri Tool’s Laser Dimensioning System (LDS) was designed to measure open-ended pipes using laser sensors as the measuring device.

The laser sensors measure displacement (position) against a target (surface of the pipe) without requiring contact with the surface.

The digital laser sensor array is mounted on a rotating platform and is firmly secured to the ID of the pipe using self-centering support legs. An algorithm corrects for any installation misalignment. The rotating platform is driven by a precision motor capable of accurately moving the laser sensors to predetermined positions along the circumference of the pipe.

The laser sensors measure distances in relation to the pipe surface and convert those measurements into information such as ID, OD, and wall thickness. The system software then records the data in familiar and easy to use Excel and PDF reports that can be exported for further analysis.
