Flexible, armored pipes and methods of using the same are disclosed. In an exemplary embodiment, the flexible, armored pipe includes an inner liner which is surrounded by a pressure armor. The inner liner may be built-up by joining together profiles that have a number of recesses. In one embodiment, the profiles are configured as K-profiles, which have recesses that are arranged in adjoining surfaces of the profile. When the profiles are brought together, the recesses form a cavity in which a locking element can be inserted, the function of which is to prevent displacement of the K-profiles at right-angles to the axial direction of the pipe when exposed to axial, compressive forces. The locking element can be I-shaped, circular or configured as a wire with a C-shaped cross-section. The locking element can also be made either of a rigid or an elastic, deformable material. With a C-shaped locking element, the whole of the cavity, which is formed by the recesses, is not filled out. A channel is thereby formed through which undesired fluids can be led away or through which cleaning fluids can be introduced.

1. A flexible, armored pipe, the pipe comprising: (A) an inner liner; and (B) a spirally-wound pressure armor surrounding said inner liner, said pressure armor comprising: (a) a number of adjoining armor profiles, each of said profiles having a number of recesses, at least two of said recesses
1. A flexible, armored pipe, the pipe comprising: (A) an inner liner; and (B) a spirally-wound pressure armor surrounding said inner liner, said pressure armor comprising: (a) a number of adjoining armor profiles, each of said profiles having a number of recesses, at least two of said recesses being provided along surfaces of said adjoining armor profiles forming a cavity therebetween; and(b) a number of locking profiles, said locking profiles being adapted to hold together said adjoining profiles; wherein said at least two recesses are locking recesses and further wherein said formed cavity accommodates a locking element. 2. The pipe according to claim 1, wherein each of said amour profiles is configured as a K-profile with four recesses.3. The pipe according to claim 2, wherein the K-profile includes two recesses which are arranged in the corners of each profile, and further wherein an I-profile is provided in a cavity which is formed by the two recesses in adjoining profiles.4. The pipe according to claim 1, wherein the locking element wholly or partly fills out the cavity.5. The pipe according to claim 1, wherein the locking element is configured as an I-profile.6. The pipe according to claim 1, wherein the at least two recesses are semicircular in shape.7. The pipe according to claim 6, wherein the locking element is configured with a substantially circular cross-section.8. The pipe according to claim 1, wherein the locking element is made of an elastic, deformable material.9. The pipe according to claim 1, wherein the locking element is configured as a wire with a C-shaped cross-section.10. The pipe according to claim 1, wherein the locking profiles are C-shaped.11. The pipe according to claim 1, wherein the profiles consist of a material which wholly or party is made of metal, a metal alloy or a ceramic-reinforced metal material.12. The pipe according to claim 1, wherein the profiles consist of a material which wholly or party is made of polymer or an armored polymer.13. The pipe according to claim 1, wherein the inner liner surrounds a carcass, the carcass being configured as the pressure armor.14. A method of using a flexible, armored pipe according to any of claims 1-13, wherein the method comprises transporting fluid with the flexible, armored pipe.15. A method according to claim 14, wherein the fluid is water.16. A method according to claim 14, wherein the fluid is ammonia.17. A method according to claim 14, wherein the fluid is hydrocarbons.
