X-ray pipeline crawler is a device for omnidirectional X-ray
filming of pipeline butt welds in pipeline laying engineering. Use
a traction trolley to bring the circumferential X-ray flaw detector
into the pipeline. In non-destructive tests for long-distance
pipelines, traditional pipeline crawlers use radioactive isotopes
as the instruction resources which emit gamma rays harming human
and environment to a certain extent.
To solve this problem, a new kind of operational control system
with magnetic positioning sensors was developed. The new crawler
possesses a strong anti-interference ability, practicability,
stability, safety and environmental protection.
