Cryogenic storage tanks are equipment used to store liquid oxygen, nitrogen, argon, carbon dioxide and other media, and there is no unified standard for their design definition. According to different process requirements and media storage methods, cryogenic storage tanks are mainly divided into the following types:
Single-vessel tank
This type of tank usually consists of a steel inner tank with an insulated shell, and the structure is relatively simple.
Double-vessel tank
It consists of a steel inner tank and an outer tank made of steel or concrete (usually prestressed concrete), and the insulation is located between the inner and outer tank walls. This structure has good thermal insulation effect and safety.
Full-container tank
Similar to a double-container tank, it consists of two containers, inside and outside, but may differ in some design details or use.
In addition, from the perspective of application and manufacturing materials, cryogenic storage tanks are classified as follows:
Large cryogenic storage tanks
widely used in various industrial fields, including single-shell metal-shell tanks, double-shell metal-shell tanks, and concrete-shell plus double-shell metal-shell tanks (prestressed concrete tanks). These tanks have their own characteristics, such as single-layer metal shell storage tanks have simple structure and low cost, but the thermal insulation effect and safety are not as good as double-layer metal shell storage tanks; Prestressed concrete tanks have greater resistance to deformation and a lower coefficient of thermal expansion.
Cryogenic liquid storage tank
generally refers to a double-layer insulated and low-temperature resistant structure container, with vacuum powder or multi-layer winding insulation in the middle, with various specifications and pressure levels can also be customized. As one of the most common equipment in industrial manufacturing, these tanks are widely used in industries such as steel manufacturing, automobile manufacturing, shipbuilding, machining, chemical, medical, food, electronics, and glass.
In summary, there are various types of cryogenic storage tanks, and the choice of which type of storage tank depends mainly on the specific process requirements, media storage methods, and use scenarios. When purchasing and using cryogenic storage tanks, it is recommended to consult professionals or relevant manufacturers to ensure that they meet actual needs and are safe and reliable.
