The various techniques that have previously been proposed for reducing peak stresses in pressure vessel nozzles by making the nozzle hole elliptical rather than circular are summarised. It is then shown that for nozzles in thick-walled cylindrical pressure vessels the optimal hole shape is likely ...

This significantly enhances the efficiency of local stress analysis at pressure vessel nozzles. Furthermore, the publicly available plugin automates and standardizes the process of local stress analysis. This eliminates subjectivity in the analysis process, such as stress linearization. Lastly, users can...
The following are acceptable types of welded nozzle designs and other connections to pressure vessel shells, heads and other geometries. For additional details, see ASME PVCS Section VIII - Division 1. Acceptable Nozzle Weld and Designs Notes Nozzle with integral reinforcement. For designs that ...
A replacement nozzle and method for replacing a nozzle in a pressure vessel. The original nozzle is removed and a weld preparation is machined into the original weld. The vacated nozzle hole is partially drilled out from the interior of the vessel. A weld land sleeve is received in the drill...
