The invention relates to a process for the manufacture of reinforced- reinforced pressure vessels and the product produced therefrom. A ductile metal vessel liner, being formed with at least one nozzle, is wrapped with a first composite layer of resin-impregnated fibers. Pressure is applied to the vess el sufficient to yield the liner but is insufficient to cause deformation of th e nozzle. The liner retains a residual compressive stress critical for withstanding cyclical service pressures. A second composite layer is applied over the first layer to increase the strength of the vessel sufficient to maintain the vessel's integrity at very high cyclical service pressures (such as about 0 - 10,000 psig). The vessel is then pressure tested at 1.5 times the intended service pressure to ensure vessel integrity. |
