ABSTRACT:
This invention relates to a flexible metal pipe covered with an impermeable sheath of a shrinkable, preferably semicrystalline polymer or polymers, characterized in that it incorporates between the shrinkable polymer sheath and the metal pipe an intermediate elastomer layer (8), optionally vulcanized or reticulated, and/or a TPE in the form of a continuous tubular sleeve (FIG. 3) or of a tape (FIG. 4 to 6). Sheathed pipes of this type are particularly suitable for flexible pipelines, optionally with suitable supports, for carrying oil and gas.
