Hemispherical heador elliptical head is thin-walled structure used in containers, commonly employed in equipment such as pressure vessels and storage tanks. The introduction of nozzle openings in heads creates stress concentration issues that may affect the strength and stability of the head. Therefore, head manufacturers need to conduct stress analysis to evaluate the stress conditions in the nozzle opening areas.

First, the head manufacturer will consider the selection of opening positions and sizes.

Second, the head manufacturer will perform stress calculations for the nozzle opening areas.

Furthermore, the head manufacturer will optimize the head design based on the stress analysis results.

In summary, the head manufacturer conducts stress analysis on head nozzle openings to assess the stress conditions in the opening areas and ensures the safety and reliability of the head through design optimization.
