METHOD FOR MAKING A PLATED STEEL ARMOURING WIRE FOR A FLEXIBLE TUBULAR PIPE TRANSPORTING HYDROCARBONS, AND ARMOURED PIPE |
| 摘要 |
The invention concerns a method for making steel plated armouring wires (20) designed to reinforce flexible tubular pipes for transporting hydrocarbons, wherein a plating coat (22) is intimately associated, through great pressure, with a hardenable steel web (21) selected with average mechanical properties, then the resulting plated wire is subjected to quick hardening at high temperature followed by tempering. |
