Elliptical headsand torispherical heads are both commonly used pressure vessel heads. Their main differences lie in the following aspects: geometric shape, circumferential length, pressure-bearing capacity, and manufacturing processes.

Each type of head has its own characteristics, and designers should select the appropriate head based on specific application requirements and cost considerations. Additionally:Elliptical heads are more suitable for vessels with moderate pressure requirements.Torispherical heads are better suited for applications requiring higher pressure resistance and increased volumetric capacity.In practical applications, the final selection depends on factors such as design specifications, fabrication complexity, and material selection.
