Abstract:

An exploratory experimental study was conducted to evaluate the stacked-ringand segmented-wall pressure vessel concepts. The evaluation consisted of1 testing to destruction stacked-ring and segmented-wall pressure vessel models with tie-rod end- closure restraints and 2 evaluating a series of seal designs utilized in the sealing of the joints between the pressure vessel end closures and the cylindrical pressure vessel body. The test results indicate that the stacked-ring pressure vessel design is approximately 50 heavier than a multi-layered pressure vessel of same internal diameter, length, material, and pressure capability. The segmented-wall pressure vessel design is approximately 8 to 9 times heavier than a multilayered pressure vessel of same diameter, length, material, and pressure capability. The free-floating, self-energizing radial seal system provided the most relaible and extrusion-roof sealing for vessels with considerable radial dilation and axial end-closure movement. Author-PL
