FIELD: machine building.
SUBSTANCE: device for inspection and repair of pipelines corresponding to robotised complex consists of facilities for transfer, fastening, inspection and repair of pipeline sections. Also, power of flow transfers the complex in pipeline by means of two toroid elastic elements arranged in front and back on the robotised complex downstream. The complex is equipped with an elastic branch pressure tight connected to toroid elastic elements. The device is inserted into the pipeline and is transferred in it to a place of damaged section detection. It is secured near the damaged section while the repair operations are carried on. Also, the device moves in the pipeline under effect of flow power and pressure tight isolates the area of the damaged section by spreading elastic elements of the device. These elements are located on external boundary of the damaged and repaired section. Flow is directed via a temporary pipeline formed by means of the device.
EFFECT: inspection and repair of pipelines without operation shut down.
