END-FITTING FOR FLEXIBLE PIPE

摘要

The invention concerns a fixing end-fitting for a flexible tubular pipe comprising an inner sealing sheath (2), a pressure vault consisting of a short-pitch helical winding (3) of a metal forming wire, an intermediate sheath (5) and at least a web of tensile long-pitch wound armour wires (6) and an outer sealing sheath (78), the end-fitting comprising a staged part (112) capable of sliding into a staged cylindrical housing of the end-fitting and designed to ensure through two crimping elements (113, 116), the sealed fixing of the inner sheath and the intermediate sheath (5), screws (120) enabling the staged part (112) to be brought closer and to be fixed on the end-fitting. The invention is characterised in that the staged part (112) and the deformable elements (113, 116) constitute three separate elements, thereby facilitating mounting and providing a better control of tightness.
