Abstract
A flexible tubular hose, in particular for transporting fluids under pressure, comprising pressure-resistant armoring constituted by winding at least one pair of interlockable metal section wires, one of which has a T-section and the other of which has a U-section, the ribs of the T-section wire being directed toward the outside of the flexible tubular hose and the ribs of the U-section wire being directed toward the axis of the flexible tubular hose. The area of the cross section of the T-section wire (,) is substantially greater than the area of the cross section of the U-section wire (,), and in each lateral interlock zone constituted on the one hand by a lateral rib (,) of the U-section wire (,) engaged in a lateral groove of the T-section wire (,), and on the other hand by a lateral rib (,) of the T-section wire facing the base portion (,) of the U-section wire between the two ribs (,) of this U-section wire, there is both contact between the lateral rib of a first of the two section wires and the second section wire, and radial clearance between the lateral rib of the second section wire and the first section wire.
