An armoured flexible pipe has an inner liner (3) surrounded by a pressure armour (5, 6) that is surrounded by a tensile armour (7, 8). The pressure armour (5, 6) is constructed from a number of profiles (5, 6, 10, 11, 12, 14, 14 a, 14b, 14c) which may engage with each other. In order to obtain optim
An armoured flexible pipe has an inner liner (3) surrounded by a pressure armour (5, 6) that is surrounded by a tensile armour (7, 8). The pressure armour (5, 6) is constructed from a number of profiles (5, 6, 10, 11, 12, 14, 14 a, 14b, 14c) which may engage with each other. In order to obtain optimum functionality, the profiles are shaped as X profiles (14, 14a, 14b, 14c ) which are kept together with another type of profile, e.g. C or T type profiles. In one embodiment, the X profiles have an open channel ( 17). In this way gas or liquid, such as rinsing fluid, may be pumped through the armour layer, from one end of the pipe to the other end. In particular, the armoured flexible pipe is useful for conveying fluids such as water, ammonia, hydrocarbons, etc.

What is claimed is: 1. An armored flexible offshore pipe comprising; an inner liner for preventing fluids from flowing in and out of the interior of the pipe, and surrounded by a helically wound pressure armor; the pressure armor comprising a plurality of X-profiles mechanically kept together with profiles of another type; each X-profile having opposed edge faces, with the edge faces of adjacent X-profiles directed toward each other; each X-profile having an outer face between the opposed edge faces of that X-profile and comprising an outer surface of the pressure armor; each X-profile having an inner face comprising an inner surface of the pressure armor; each X-profile having at least two locking folds operative for engagement with respective profiles of the other type; and the locking folds of each X-profile being located between the edge faces and the outer face of that X-profile. 2. A flexible pipe according to claim 1, characterized in that: the other type of profile is a C type profile having an outer face in substantial alignment with the outer faces of the X-profiles and an inner face in substantial alignment with the inner faces of the X-profiles; and each other profile comprises two locking folds extending inwardly from the outer face of the other profile to engage respective locking folds of the X-profile adjacent to the respective other profile. 3. A flexible pipe according to claim 1, characterized in that: the other type of profile is a T type profile having an outer face in substantial alignment with the outer faces of the X-profiles and a member extending inwardly from the outer face to lie between edge faces of adjacent X-profiles, so that the member maintains a space between the edge faces of the adjacent X-profiles. 4. A flexible pipe according to claim 1, characterized in that a number of X profiles are kept together by means of twice the number of C profiles and/or T profiles. 5. A flexible pipe according to claim 1, characterized in that an edge face of the X-profile is provided with at least one channel open at the edge face and in substantial alignment with an open channel in the confronting edge face of the adjacent X-profile. 6. A flexible pipe according to claim 5, characterized in that the aligned channels in the confronting X-profiles are between the outer faces and inner faces of the X-profiles so as to form a continuous channel from one end of the pressure armor of the pipe to the other end of the pressure armor. 7. A flexible pipe according to claim 1, characterized in that the pressure armor is of a material which is fully or partially made of a metal, a metal alloy, or a ceramically reinforced metal material. 8. A flexible pipe according to claim 7, characterized in that the material contains at least 50% Fe. 9. A flexible pipe according to claim 7, characterized in that the material is fully or partially made of a polymer or a reinforced polymer. 10. A flexible pipe according to claim 9, characterized in that the material contains more than 20% reinforcing fibres. 11. A use of an armored flexible pipe according to claim 1, for conveying fluids such as water, ammonia and hydrocarbons. 12. An armored flexible offshore pipe as in claim 1, wherein: each X-profile has four locking folds, and: two of the locking folds of each X-profile are located between the edge faces and the inner face of the X-profile, whereby the locking folds engage respective profiles of the other type to form the pressure armor.
