Why spherical tank

To complete the equipment form, there's even a range of end cap choices. These headers, shaped as hemispherical half spheres or torispherical flattened dish end elements, imbue cylindrical fluid storage vessels with subtly different pressure handling facilities.

Finally, leaning heavily on the practical perspective, it's not easy to manufacture a completely spheroidal storage unit. As a compromise of sorts, rolled cylindrical panels, which are welded into wide-diameter tubes, are mounted with spheroid-like headers. Here's another important point, one that effects processing plant design. If a cylindrically profiled pressure vessel gains a capacity increase, we just have to return to the fabrication yard to make the alterations.

A new replacement unit gains cylindrical length, plus a slight increase in its diameter. It climbs higher in the processing facility, so there's more support framework to add to the design. If spheroidal pressure vessels receive a capacity boost, the matter is so much harder to resolve.

The diameter of the sphere widens, for there is no separate tubular section to alter. That entire sphere needs to grow in size to accommodate the larger fluid load. Still, assuming the facility doesn't require scaling, spheres are the superior force spreading solution. And, instead of bringing in larger metal balls, the designer can always add a second equally sized spherical pressure vessel. Procurement, installation, and protection of above and below ground piping.
