Abstract
A fixing end-fitting for a flexible tubular pipe, the pipe comprising an inner sealing sheath, a pressure vault comprising a short-pitch helical winding of a metal forming wire, an intermediate sheath and at least a web of tensile long-pitch wound armour wires and an outer sealing sheath. The end-fitting comprises a stepped part capable of sliding into a stepped cylindrical housing of the end-fitting. Two crimping elements sealingly fix the inner sheath and the intermediate sheath. Screws enable the stepped part to be brought closer to and be fixed on the end-fitting. The stepped part and the deformable elements constitute three separate elements, thereby facilitating mounting and providing a better control of tightness.
