<p>Composite pipe (20) of the type comprising an inner tube (2) made of a first thermoplastic material (A), a reinforcement (21), comprising a metal strip (3) which is bonded to the inner tube by a first adhesive (61) compatible with the first thermoplastic material, an outer sheath (4) of a second thermoplastic material (B), which is bonded to the renforcement (21) by a second adhesive (62) compatible with the second thermoplastic material. According to the invention, the two materials A and B are chemically different and, in the joining area (22) between the oppositely facing strips (61a, 62a), of the first and second adhesive, the two strips are coherently linked by coupling means. In an embodiment, the coupling means consist of different adhesives which are compatible and cross-linkable with one another.</p> |
