Automated Radiographic Testing (ART) Crawler
Advanced inspection tools to check for piping corrosion
Page last modified
April 11 2024
MISTRAS’ multi-view radiography crawler provides an efficient means to screen insulated piping systems for CUI. Our ART Crawler has been designed to provide unrivalled inspection efficiencies for in-plant and off-site insulated piping.
The ART Crawler utilises a low-voltage X-ray and real-time imaging to screen for CUI at four locations (top, bottom, and sides) of the pipe. The small size and low weight of the Crawler ensures deployment at height via rope access as well as tackling congested pipe racks.
Pros & Limitations
1
CUI tool utilising x-ray radiation energy and proprietary detectors to image for corrosion in real-time
1
Solution is robotically controlled and therefore provides a cost-effective method for large scale screening, upwards of a 100m of pipe per day
1
Decreased risk of radiation exposure, increasing safety measures
1
Recorded images are digitally stored, providing a long-term, easily traceable, and readily-available record of corrosion
1
Can be used to identify the presence of water saturation within the insulation material
1
Fully wireless and weatherproof
1
Three-axis robotic arm to traverse pipe supports
0
The ART Crawler is designed to provide an efficient screening tool for CUI and is not primarily designed to provide absolute measurements of remaining wall thickness
0
Designed for pipe diameters from 2 to 20” insulated
