Abstract: The invention relates to a flexible, typically un-bonded, armoured pipe having a centre axis and comprising an inner liner surrounded by a radial armouring and an axial armouring, the radial and axial armouring each comprising at least one armouring layer of armouring profiles wound with winding angles α innermost relative to the centre axis, wherein the winding angle of the innermost armouring layer innermost is larger than the winding angle of the outermost armouring layer α outermost . The invention further relates to a method of manufacturing a flexible pipe and to its use. The object of the present invention is to provide a pipe with an outer radial armouring layer having sufficient strength and flexibility to prevent prohibitively large radial deformations of underlying axial armouring layers without considerably increasing the radial contact pressure on underlying axial armouring layer. The object is achieved by a flexible pipe comprising at least one fibrous layer surrounding the outermost armouring layer wherein said fibrous layer comprises at least two fibrous cords wound on an underlying layer. A flexible pipe according to the invention is e.g. useful in terrestric and/or subsea transport of fluids, e.g. oil or gas, at elevated temperatures and/or pressures.

Abstract: 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).

Abstract: The invention relates to a pipe structure (100) for transporting a fluid substance in a physical environment (180), and especially to the problems of sealing of a to-be-sealed interface (111) between a sealing layer (102) of a flexible pipe and an end fitting (101) for connecting the flexible pipe to an installation or to another pipe. The object of the present invention is to provide a pipe structure with a sealing that is relatively simple and able to be self-sealing in the sense that it relaxes the need for built-in compressive forces working on the sealing part. The problem is solved in that the pipe structure (100) further comprises a sealing part for sealing to-be-sealed interface (111), where the sealing part comprises an annular gasket (104) pressing the annular gasket against, respectively, the sealing layer (102) and the end fitting (101), e.g. by means of a pressing element (124). This has the advantage of providing an alternative to the traditional “solid type” sealing element (such as an O-ring or other geometrically formed solid elements). It provides a design freedom in adapting the area and shape of the surface of contact with to-be-sealed surfaces, in choice of materials, in combination with other functional elements, etc. the invention may e.g. be used in connection with the transport of pressurized liquids and gases (e.g. hydrocarbons, water, etc.) in a flexible pipe at elevated temperatures in marine environments.
