Comparison of design methods for openings in cylindrical shells under internal pressure reinforced by flush (set-on) nozzles

In this paper a comprehensive comparison of three design methods for openings in cylindrical shells under internal pressure (pressure vessels) reinforced by flush (set-on) nozzles has been carried out. The design methods are used in EN 13445-3: Unfired pressure vessels-Part 3: Design, ASME pressure vessel code and PD 5500: Specification for unfired fusion welded pressure vessels. The calculation procedures used in the three methods are significantly different, so the comparison has been based on the maximum permissible design pressures for 45 specific geometries calculated using the three methods.
