The Arrow-5M is a versatile self-propelled X-ray crawler designed for internal radiographic inspection of medium-diameter pipelines widely used in the oil and gas industry. The unit transports the X-ray generator inside the pipeline to deliver panoramic or directional exposures directly at each weld joint, eliminating the need for external source placement. Its magnetic positioning system guarantees accurate and repeatable stopping at designated weld locations, reducing setup time and ensuring consistent inspection quality across long pipeline sections.
Engineered to handle the most common pipeline diameters encountered in trunk lines, transmission networks, and processing plant interconnections, the Arrow-5M is a workhorse solution for high-volume weld inspection campaigns. The crawler is built to withstand the rigorous operational demands of large-scale pipeline construction projects across Saudi Arabia, the UAE, Oman, and the broader Middle East region.

The working structure is divided into three lightweight units (crawler, battery, generator), making assembly convenient for two people.
The model range (Arrow 3M–7M) allows working with pipelines from 219 to 1420 mm.
Forced air flow to the generator while driving reduces downtime between exposures.
The remote magnetic positioning system ensures stopping accuracy with an error of up to 0.5 mm with a wall thickness of up to 35 mm.
Mitsubishi Electric controllers guarantee stable operation and trouble-free automation.
