Flexible Pipe for Transporting Fresh Water, Set for the Storage Thereof and Assembly of a Plurality of Pipes

A flexible pipe elongate along an axis, adapted to transport fresh water, able to be wound longitudinally on a drum or folded in a container, longitudinally continuous, of circular section when there is a positive differential pressure between the interior of the pipe and the exterior, the section of which can be crushed on itself by the effect of a negative differential pressure, the pipe having an outside diameter (D1) between 1 and 7 meters and comprising an envelope impermeable to the transported liquid, wherein the pipe has a length (L1) between 200 and 3000 meters and comprises at least two peripheral reinforcing elements increasing the mechanical strength of the pipe relative to a positive differential pressure and the pipe withstands without bursting or splitting a positive differential pressure from 1 to at least 10×105 Pa.
