  • the vapor-compression process consists in the latest evolution of the distillation method, wherein vaporization takes place at relatively low temperatures, since the process occurs under partial vacuum conditions. These processes depend upon a high energy consumption, high production cost, low productivity of drinkable water, and the equipment is expensive.
  • the option for transporting water through land and/or air water-mains is limited to short distances due to geographic conditions, and the unfavorable conditions often render the construction impossible.
  • the large land water-mains have the following drawbacks: (i) the penstocks of the water-mains that have large diameters require a great structural effort to resist the deformation caused by the action of the gravity force on the internal water mass of the pipes and on the structure of the pipes; (ii) large free conduits such as channels have topographic limitation, high material and construction costs and take time to carry out.
  • the invention has the objective of providing a flexible duct having large diameter and thin wall, capable of transporting a large volume of fluids to long distances and with a low loss of charge, without a deformation occurring in the diameter of the duct, with a low manufacture and installation costs and that requires a low consumption of energy for pumping the water to be conveyed.
  • An objective of the invention is to provide a flexible duct for transporting fluids, comprising a main flexible pipe, at least one fixing and anchoring pipe associated externally and parallel to the main pipe and at least one ballast associated to at least one fixing and anchoring pipe, the main pipe having the capability of being used submerged in an aqueous medium, so as to comprise a relative pressure between the pressure inside the main pipe and a substantially null external pressure from the aqueous medium, and further the capability of being subjected to a compensation of loss of charge.

  • the tension that breaks the vinylic fabric that forms the flexible duct 40 is achieved in function of the internal pressure of the main pipe 1 and also of the diameter of this pipe 1. So, the larger the pipe the greater the tension, since the latter is also related to the perimeter of the pipe 1.
  • the maximum or upper-limit height of positioning the flexible pipe 40 with respect to the lower-limit level one should consider that, with every 37 m of depth which one rises with the flexible pipe 40, the internal pressure in the main pipe 1 with respect to the external pressure increases by 1 mca. If the flexible duct is positioned above the maximum limit, it will break. In this way, the larger the diameter of the main pipe 1 , the narrower the operation range.
  • the flexible pipe 40 object of the present invention is positioned exactly in the depth that compensates the internal pressure, that is to say, in the depth that corresponds to the compensation of the piezometric line, along the main pipe 1 , there will be no increase in the internal pressure of the pipe 1 and the latter will not collapse.
