Abstract
A flexible tubular pipe comprising at least, from the inside outwards, an internal sealing sheath made of a polymer material, a cylindrical pressure vault having an external face and having an internal face placed over the internal sheath. The vault is a winding, in a helix with a short pitch and with a gap between turns, of an interlocked metal profile wire. At least one ply of tensile armour layers is wound with a long pitch. An external protective sealing sheath is made of a polymer. The fastener wire has the same height as the profile wire and is fastened below the neutral fiber of the profile wire. The ratio of the cross section of the profile wire to the cross section of the fastening wire is between 1 and 2 and the ratio of the moment of inertia Iof the profile wire to the moment of inertia Iof the fastening wire is between 1 and 2.
