Abstract: A reservoir for storing a pressurized fluid is disclosed, having a longitudinal axis and comprising a central tubular portion closed at its ends by two bottoms, one at least of which bulges outwardly and is provided with a neck, and also a method of manufacturing such a reservoir.According to the invention, said reservoir is formed by a tubular shell of a composite fiber-thermoplastic binder material and two end pieces made from a thermoplastic material strengthened with reinforcement fibers, said shell and said end pieces being secured solidly together by local heat-melted zones.

Abstract: The present invention concerns a receptacle for the storage of fluid under pressure and comprising an internal casing with axis X,X' and having one central cylindrical section and two extremity sections, an armouring encompassing said casing and leaving clear at the convex extremity section a cap centered on axis X,X'.According to the invention, the outer contour (8) of said convex extremity section (2b) of the casing (2) has, as a longitudinal section, a shape which is at least approximately elliptical so that the ratio G of the small half axis to the major axis is such that:0.32.ltoreq.G.ltoreq.0.4 (I)where the major axis corresponds to the outer diameter of the central cylindrical section (2a) of the casing (2), and the thickness e.sub.i of said convex extremity section (2b), said cap (6) being excluded, varies according to the formula: ##EQU1## in which: R.sub.i =distance to the axis X,X' of the point of the outer contour (8) of said convex extremity section (2b) at which the thickness e.sub.

Abstract: There is provided a process for providing a metal connector fixed to a pipe of composite material and a pipe thus made.A pipe carries at one of its extremities a metal connector, and a first film of elastomer being interposed between the two and adhering to each of them an adhesive. At the level of this extremity, the pipe also carries a metal casing which is held solidly on the connector by a band and a second film of an elastomer which is interposed between the casing and the pipe and adheres by means of an adhesive to each of them.The pipes according to the invention are suitable for use in offshore oil exploration.
