  • Patent number: 10189225
    Abstract: A high pressure hose having steel wires with different load elongation properties, which are introduced into the subsequent reinforcement layers of the hose. The difference in load elongation is quantified by the E-ratio of the wire that is equal to the tensile strength divided by the elongation at break. The steel wires of the radially outermost steel wire reinforcement layer have the highest E-ratio, while the radially innermost steel wire reinforcement layer has the lowest E-ratio. The E-ratio of any steel wire reinforcement layer is not lower than the E-ratio of any inner laying steel wire reinforcement layer. The E-ratio of the steel wires can be influenced by either a thermal treatment or by a mechanical treatment. In the mechanical treatment crimps or bends can be introduced into the wire by guiding them through a preforming device.
