FIELD: mechanical engineering.
SUBSTANCE: device comprises chambers with sleeves ends of which are unbent and fixed on the perimetre of the pipeline. Cavities formed by the unbent sites of the sleeves are connected with fluid agent supply systems. The drums are mounted out of a longitudinal axis of the pipeline. One end of the sleeve is fixed on the perimetre of the pipeline, while the second end of the sleeve is connected through hoisting slings with a flexible coupler an end of which is connected with a traction organ. The device is supplied with a pipe stopper represented in the form of a torus mounted on the pipe connected to a hollow cylinder. The device may comprise an additional chamber with a sleeve an end of which is fixed on the perimetre of the pipeline, while the second end of the sleeve is connected through hoisting slings with a flexible coupler connected to the traction body.
EFFECT: extended range of the instruments.
