Why don’t you move? There are manholes at the bottom as well as drain holes
Stress analysis was conducted on the openings at the upper and lower poles, which are among the most important structures of the spherical tank, in accordance with the design standard JB4732-1995. During the analysis, the stress conditions under both design and hydrostatic test conditions were taken into account. To ensure the safety of the equipment, strict standards are followed during the selection of the path. Finite element analysis was conducted on both the upper and lower poles, and the results were verified by considering both stress alone and stress combined with secondary stress; all results met the strength verification criteria.

For containers such as spherical tanks, should the manhole at the top be opened first or the one at the bottom when opening the tank? https://bbs.hcbbs.com/thread-1486400-1-1.html (Source: Haichuan Chemical Industry Forum)
GB 12337-2014 5.6.5 For spherical tanks containing media with extremely high or high toxicity, openings at the inlet and outlet should be provided at higher levels
It can be used, but it is recommended to use it as little as possible to avoid reducing strength and minimizing leaks
