The wire is made of a steel with at least the following analysis, given in concentrations by weight relative to the iron: 0.04%=C=1.00%, 0.70%=Ni=5.00%, 0.30%=Mn=1.20%, Cr=2%, 0.10%=Si=1.70%, S=0.035%, P=0.035%. Fabrication of the wire involves hot drawing, phosphatation, cold drawing, heat treatment by quenching, cooling to ambient and coiling the wire : An independent claim is made for a flexible pipe for the transport of fluids containing at least one layer of armour made of a shaped wire as described above. |
