Zusammenfassung:	PCT No. PCT/FR97/00190 Sec. 371 Date Aug. 3, 1998 Sec. 102(e) Date Aug. 3, 1998 PCT Filed Jan. 31, 1997 PCT Pub. No. WO97/28393 PCT Pub. Date Aug. 7, 1997A flexible pipe including at least one sealing liner (1); an assembly (3) of external reinforcements for withstanding the physical and chemical stress to which the flexible pipe is exposed, which assembly particularly comprises a reinforcement (2) resistant to the pressure of the fluid to be conveyed and consisting of non-contiguous coils (7,8) wound around said sealing liner (1) in a predetermined direction (e); and an intermediate strip (11) arranged between the pressure-resistant reinforcement (2) and the sealing liner (1), and wound around said sealing liner in a direction parallel or opposite to the winding direction (e) of the coils of the pressure-resistant reinforcement. The intermediate strip (11) has a low modulus of stiffness in said winding direction (3) around the sealing liner, and a high strength and modulus of stiffness in a transverse direction (e') relative to said coil winding direction.
