The Arrow-6M is a high-capacity self-propelled X-ray crawler engineered for internal radiographic inspection of large-diameter pipelines critical to oil and gas transportation infrastructure. It carries the X-ray generator through expansive pipe interiors, positioning the radiation source with precision at each circumferential weld for superior image quality and full volumetric coverage. The advanced magnetic positioning system delivers exceptional stopping accuracy even over extended travel distances, ensuring efficient and reliable inspection of every weld joint along the pipeline route.
Purpose-built for large-bore transmission pipelines, subsea tie-ins, and major cross-country pipeline projects, the Arrow-6M offers the mechanical strength and operational endurance required for the most demanding field environments. It is a preferred solution for national oil companies and EPC contractors executing strategic pipeline infrastructure programs throughout the Middle East, including projects in Saudi Arabia, the UAE, Qatar, Kuwait, and Oman.

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.
