DEVICE FOR CLEANING OF THE INTERNAL CAVITIES OF THE PIPELINE Russian patent published in 2007 - IPC B08B9/53 

FIELD: oil-producing industry; gas-production industry; device for cleaning of the internal cavities of the pipelines.

SUBSTANCE: the invention is pertaining to the device for cleaning of the internal cavities of the hollow items, for example, the pipelines from inside by means of the moving tools and removal of the sediments from the cavity of the pipelines and ensures the increase of the productivity due to the increase of the increase of the number of the rounds per a minute of the arbor without increase of the working agent consumption, and also ensures simplification of the design, the increased service life, repairability and the expansion of the technological functions. The system consists of: the nose-piece with the cutting edges, mounted on the arbor, which has the blades; and also the body; the reactive, turbine and pressure chambers; the fitting pipe for feeding the working agent. The turbine chamber is made in the form of the hollow cylinder mounted inside the pressure chamber and has holes on the lateral wall for the guided feeding of the working agent onto the blades and rotating of the arbor. At that the blades are arranged along the axis of the arbor at the angle of α to the imaginary plane, in which the arbor axis lies - within the limits from 0° up to 90°.

EFFECT: the invention ensures cleaning and removal of the sediments from the internal cavities of the pipelines, reduction of the working agent consumption, simplification of the design, the increased service life and improved repairability, the expansion of the technological functions, the increased productivity.
