Storage tanks are storage equipment that stores crude oil, gasoline, kerosene, naphtha, and various non-volatile chemicals. They are an important part of storage and transportation system facilities, oil refining, and chemical plants.

Why is the storage tank spherical? Because of all the shapes, the sphere is the structure with the best pressure capacity, the most stable, and the largest capacity. Therefore, most of the storage tanks are spherical.

Dalian Jiuying's spherical head machine specially manufactures this large spherical head.
