Abstract
The present invention relates to a reinforced undersea unit pipe element () suitable for being laid empty at great depth. The element includes a tubular wall, having at least one external peripheral reinforcing element () creating a plurality of localized zones on the outside surface of the wall, the radial distance (d) between the outside surface of the pipe and the longitudinal axis (XX') of the wall in the zones being greater than the outside radius (R) of the tubular wall portions lying between the successive zones in the longitudinal direction (XX′), two successive ones of the zones being spaced apart in the longitudinal direction (XX′) of the tubular wall by a distance (D) equal to ½ to 4 times the outside diameter (d) of the tubular wall portions, the successive zones preferably being spaced apart regularly.
