摘要： A flexible, typically un-bonded, armored pipe, and a method manufacturing a flexible pipe. The pipe has a center axis and comprises an inner liner surrounded by a radial armoring and an axial armoring, the radial and axial armoring each comprising at least one armoring layer of armoring profiles wound with winding angles αi relative to the center axis. The winding angle of the innermost armoring layer αinnermost is larger than the winding angle of the outermost armoring layer αoutermost. The outer radial armoring layer has sufficient strength and flexibility to prevent prohibitively large radial deformations of underlying axial armoring layers without considerably increasing the radial contact pressure on underlying axial armoring layer. At least one fibrous layer, comprising at least two fibrous cords wound on an underlying layer, surrounds the outermost armoring layer. The flexible pipe is useful in terrestrial and/or subsea transport of fluids at elevated temperature and/or pressures.

摘要： The invention relates to a pipe structure (10) comprising a length of a flexible pipe connected to an end fitting, the flexible pipe comprising an armour layer (11; 19) and an underlying pipe layer (12; 11) to said armour layer, said underlying pipe layer having an outer surface around which armouring wires (111; 191) of an armouring layer are helically wound. The object of the present invention is to provide a coupling between a flexible pipe comprising armouring wires and an end fitting, the coupling exerting a relatively low bending or flexure strain on the wires during normal operation of the flexible pipe. The problem is solved in that the transition path of an armouring wire between the flexible pipe and the end fitting comprises an straight-line-section (194) between a wire-pipe-exit-point (195) where the wire extends away from its underlying pipe layer and a straight-line-end-point (196) on a support unit (15) of the end fitting where the armouring wire in question has its first tangential point of contact. This ahs the advantage that in a loaded situation where the armouring wires will elongate elastically leading to a change in the helical angle of the armouring wires, a pipe structure according to the invention will experience a slight twist and a controlled bending of the armouring wires on the surface of the support unit (due to a possible change in the base point of contact of the armouring wire with the support unit induced by the change of helical angle), thereby avoiding substantial bending of the individual armouring wires, which is of particular importance when the armouring wires are formed of a composite material. The invention may be used in flexible pipes for the off shore transport of fluids (e.g. oil).

摘要： A flexible pipe for transporting a fluid in a marine environment. The pipe comprises a liner for confining the fluid, an armoring layer surrounding the liner, and an outer protective sheath surrounding the armoring layer and allowing radial expansion and contraction of the armoring layers. The outer protective sheath comprises at least two protective layers of helically wound composite wires with essentially opposite winding angles and locally held together, providing a relatively flexible yet fixed structure of the outer sheath. The outer sheath is held together in an array of discrete spots or along linear or curved paths. Flexibility is maintained because the stiffness in shear in the wires of adjacent protective layers may be made much larger in areas being locally held together than outside these areas. This allows a change of angles between the wires of two adjacent layers of the outer protective sheath during elongation or shortening of the pipe.
