Flexible long-dimensioned flat-drained pipeline (pulp conduit) is manufactured from 150 to 1200 mm in diameter. It is characterized by a low mass (one meter of a flat-rolled slurry pipeline with a diameter of 450 mm designed for a working pressure of 0.4 mPa can weigh from 4.5 kg). Small mass and flatness of the slurry pipeline makes it possible to transport them, wound on a drum, by any means of transport, including aviation. Ploskorvorachivaemy pipeline is recommended to be used as an operational slurry line for hydroscheme on shore dumps, for construction of temporary water conduits and earth dams by means of hydromechanization, as primary depositions of cards for deposition.
