Abstract

The invention relates to a flexible pipe comprising a plurality of layers surrounding a longitudinal axis of the pipe, the plurality of layers comprising from inside and radially outwards an internal sheath (2), a pressure vault (3) and one or more tensile armouring layers (4,5). The pressure vault comprises at least one helically wound folded metal strip, which folded metal strip is interlocked with itself in consecutive windings or interlocked with another helically wound metal strip. The at least one folded metal strip is folded along both of its edges to form protruding edge sections (316) of two or more strip material layers, each of said protruding edge sections protruding in one of the directions towards or away from the longitudinal axis of the pipe. The pressure vault of the flexible pipe of the invention has a high strength while simultaneously being very flexible. Furthermore, the pressure vault is very simple to produce and apply, and the cost of the pressure vault is very beneficial compared with the cost of prior art pressure vaults.
