    摘要: The pipe (1) comprises at least one bracing ply (3) arranged between an internal tube (2) and an external protective tube (2), the method being characterised in that it consists in exposing at least one zone of said bracing ply, injecting into said exposed zone of the bracing ply (3) a heat hardening compound, so as to obtain after hardening said one external part of the pipe hardened by said compound capable of being used for standard tapping systems. The invention is useful for pipes in which flows a fluid such as water or gas.

    摘要: The invention concerns a flexible conduit comprising an internal gasproof undulating metal tube (1), the wall of which has helical undulations (8), the external surface of said internal tube having at least concave (10) and convex (11) rounded parts corresponding to the internal and external parts of the undulations respectively, and at least an arch (2) arranged around said internal metal tube and made up of at least a form wire (9) coiled in spires. The invention is characterised in that the arch (2) has an internal surface with helical undulation, comprising at least concave (16) and convex (15) rounded parts and the external surface of the internal metal tube is supported in its concave rounded part (10) by a convex part (15) of the arch (2) internal surface and in its convex rounded part (11) by a concave part (16) of the arch internal surface, said internal arch surface and said internal tube external surface matching in form, and the interstices (i) between the adjacent spires are small. The invention is particularly applicable to flexible conduits used in oil mining.

    摘要: A duct comprising a sealed inner tube (1) and a reinforcement (2) made of at least one strip wound in a spiral around a central axis (11) of the inner tube. The strip (10) is flat and includes at least one layer of longitudinal filamentary rovings (6) and means for assembling said filamentary rovings comprising a loosely woven weft yarn (7) and a bonding material (8) provided at least at the interface between said filamentary rovings and said weft yarn. The assembly means hold the longitudinal rovings together along the full length thereof and impart a compactness of at least 39 % to said strip.

    摘要: The apparatus comprises a frame (1), an extrusion head (2), a stationary support member (5), an insert (7) arranged about said support member (5) according to a predetermined pitch, a rotary member (8) and it is characterized in that it is provided with support and centring means (19) for the support member (5); said means (19) comprise an assembly of radial elements which are angularly and longitudinaly offset about and along the axis (A) so that the bearing surface of the radial elements on the support member (5) determines a helical contact and the insert (7) may thus be displaced without obstruction in said support and centring means (19). Application particularly to the fabrication of flexible tubes used in the oil industry.
