<p>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 anglesαi relative to the center axis. The winding angle of the innermost armoring layerαinnermost is larger than the winding angle of the outermost armoring layerαoutermost. 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.</p> |
