Flexible metal pipes with a shrinkable polymer sheath, a process for their fabrication, and their utilization as flexible tubular conduits

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