Abstract
A flexible tubular pipe incorporating, from the inside outward, an inner sealing sleeve or tube, and an armoring comprising a plurality of armoring webs. The armoring includes a first armoring web on which the inner sealing sleeve or tube rests. The first armoring web includes a plurality of interlocked wires wound with an angle, (A1) that is less than 80.degree. in relation to the axis of the flexible tubular pipe. The armoring also includes a set of armoring webs placed on the outside of the first armoring web, each having at least one armoring web and non-interlocking wires. The winding angle of the wires is complementary to the angle (A1), so that a balanced flexible tubular pipe is created.
