FIELD: construction, pipeline.
SUBSTANCE: invention pertains to the field of pipelines inspection. In the pipeline inspection device containing a running head connected with external control and maintenance aids and with a source of compressed air by means of a flexible tube, running head with a towing opening for ejection of compressed gas is fixed whereon, there is a set of needles directed at the flexible tube. These needles are spread around the running head at distances defining volume, maximal value by perimeter whereof measured around the longitudinal axis of the device has a defined value somewhat lower than the diameter of the pipe or a duct under inspection.
EFFECT: use of the towing running head and possible devices and instruments for radiological and physical-chemical measurements, set centered against the pipeline under inspection.
