Abstract
In order to increase the cracking corrosion resistance of a wire under stress compressive stresses are introduced through surface treatment by brushing, on the apparent surface of the wire. A system and method are notably applied for the manufacture of wire-reinforced flexible pipes. The reinforcing wires are subjected to a surface treatment by brushing after setting the wires on the flexible pipe.
