FIELD: technological processes.
SUBSTANCE: group of inventions refers to coiled-to-reel long-length flexible tubes. Element of the long-length flexible column includes at least two closed channels in a single structure, the closed channels being interconnected by a connecting partition. Closed channels and a connecting baffle are formed from a single strip by the method of its profiling from both its edges and / or from the center by longitudinal bending thereof with the formation of the walls of closed channels, followed by welding of the longitudinal edges to the body of the profiled strip. Connecting wall is made with holes.
EFFECT: reliability of a flexible column consisting of two or more closed channels of different diameters, cross-sections and configurations freely wound onto standard drums.
