Abstract

Flexible metal tube (3) sheathed with a layer of polyvinylidene fluoride (6), characterised in that a layer (5) of polyurethane thermoplastic elastomer is placed between the metal wall (3) and the polyvinylidene fluoride layer (6). This tube is particularly suitable for the exploitation of petroleum and gases.
