摘要： A flexible metal pipe (2) is coated with a sealing sheath made of one or more shrinkable polymers, preferably of the semi-crystalline type. The invention is characterized in that an intermediate layer (8) is arranged between the shrinkable polymer sheath and the metal pipe, said layer being made of an optionally cured or crosslinked elastomer and/or a thermoplastic elastomer. Said layer is either in the form of a continuous tubular envelope (Fig. 3) or in the form of a strip (Figs. 4 to 6). The sheathed pipes of the invention are useful, in particular, in the manufacture of flexible, optionally reinforced oil and gas pipes.

摘要： An improved flexible flowline (1) for conveying fluids. From the inside to the outside, the inventive flowline comprises the following: a spirally wound flexible metal frame (2) with non-connecting coils (3), a compressible rod (10) disposed in the gap (9) between the consecutive coils of the spiral winding, an inner extruded impervious sheath (4) on said metal frame, at least one layer of armouring that is wrapped around the inner impervious sheath (4) and at least one outer impervious sheath (8) disposed around the sheet of armouring. The invention is characterised in that the compressible rod (10) has a high volumetric deformation of at least 50 % when compressed.

摘要： The invention concerns a flexible heat-insulated tubular duct for transporting fluids, produced by spiral winding, with uniform pitch and with interval between the turns, at least a strip (14) of heat insulating material around the central flexible core (11). The invention is characterised by the joint winding without clearance of an intermediate extruded profile (1) in the interval (13) between the turns of the strip, said intermediate profile (1) being produced in a material substantially incompressible in volume.

摘要： A flexible tubular pipe with an internal impervious polymeric sheath, including at least, from the inside outwards, an internal pervious metal shell (1) with an outer surface having interstices (9), an internal impervious polymeric sheath (2), a set of armouring wire webs (3, 4) and an outer protective sheath (5). Said internal impervious polymeric sheath (2) mainly includes a portion made of a thermoplastic polymer combining at least two fluoromonomers of which at least one has at least one alkoxy function, and said portion made of a thermoplastic polymer is in the form of a continuous tubular layer having no incipient tears in the region of said interstices (9).
