Designs of selected components for a container are evaluated based on conservative loads and assumptions. The items selected for evaluation are a pintle and possible container topheads. An existing pintle for use in another application is evaluated under a more severe axial load. The results show that the pintle is adequate with the existing design to a safety factor of at least three. Improvements are suggested which raises this safety factor to approximately six. Several flat tophead designs are evaluated for stress under an annular load. The parameter selected for evaluation is the thickness of the circular plate. Results from a 1.5 inch thick plate are below a safety factor of three. Results with a 2 inch plate are improved, but marginal. Analysis results indicate that a thicker pintle or a stiffer plate will improve the design. Several curved tophead shapes are analyzed under an annular load. The ASME flanged and dished shape displays more desirable properties than others. A critical parameter is identified and changed to provide acceptable stress levels.
