WebTheoretically, a sphere would be the best shape of a pressure vessel. Unhappily, a spherical shape is tough to manufacture, therefore more expensive, so most pressure vessels are cylindrical with 2:1 semi-elliptical heads or end caps on each end. Smaller pressure vessels are assembled from a pipe and two covers. http://fusionweld.com.au/pros-and-cons-of-spherical-vs-cylindrical-pressure-vessels.html#:~:text=From%20a%20purely%20theoretical%20viewpoint%2C%20spherical%20pressure%20vessels,be%20uniformly%20experienced%20by%20its%20rolled%20metal%20panels.
