What are the design shapes of pressure vessels?

Shape classification is a way to visually classify the types of pressure vessels, but what are the particularities or application characteristics of designing pressure vessels into different shapes? Triethyl aluminum storage tank

The basic structure of a cylindrical pressure vessel is a cylinder head, a nozzle, a hand hole, and a support. Its main advantage is that it is easy to manufacture and easy to set up process internals. Therefore, the production and usage are both higher than that of spherical vessels. The square container is large. Cylindrical containers are used in petroleum, liquefaction, etc. Generally, small-sized liquefied petroleum gas storage tanks are made into this type of cylindrical shape, and large-scale tanks are made of different geometric containers.

Spherical container is also called spherical tank, the shell is spherical. It is an effective and economical pressure vessel for storing and transporting various gases, liquids and liquefied gases. Compared with the cylindrical container, the main advantages are: uniform force; under the same wall thickness, the bearing capacity of the spherical tank is relatively higher. Under the same volume condition, the surface area of the spherical container is small, due to the wall thickness and small surface area For other reasons, it generally saves more steel than cylindrical containers. The main disadvantage is that the manufacturing and construction are more complicated. It is widely used in the fields of chemical industry, petroleum, oil refining, shipbuilding and city gas industry.

Rectangular containers are also called square containers. They generally carry gases or liquids with lower pressure. Nowadays, the shape design of this type of container is relatively small, because square containers are easy to deform and cause accidents, and the cost of designing rectangular containers is higher than that of round containers. So now rectangular containers are relatively rare.
