Storage tanks are also a commonly used chemical equipment, and their main function is to store liquids or gases. In addition to chemical professions, they are still essential and important basic equipment for professions such as petroleum, grain and oil, food, fire protection, transportation, metallurgy, and national defense.

Storage tanks for chemical equipment are specialized equipment for storing various liquid raw materials and products. For many enterprises, without storage tanks, production cannot proceed normally, especially for strategic material storage in China, which cannot do without storage tanks of various capacities and types. Most of China's oil storage equipment is mainly aboveground storage tanks, with metal structures being the majority. Of course, there are also many other types of storage tanks.

Due to the different storage media, there are various ways for chemical equipment storage tanks. If they are classified according to their orientation, they can be divided into aboveground storage tanks, underground storage tanks, semi underground storage tanks, offshore storage tanks, submarine storage tanks, etc; Classified by purpose, there are production oil tanks, storage oil tanks, etc; There are also structural fixed roof tanks, floating roof tanks, spherical tanks, etc.

The key point to be introduced is the requirements for the data of storage tanks when used as chemical equipment. The data required for storage tanks can be divided into two aspects: tank body data and subordinate equipment data. During this process, tank body data can be divided into low strength steel and high strength steel according to tensile yield strength or tensile specification strength. High strength steel is mostly used for 5000m ³ Above storage tanks.

There are also some subordinate equipment required on the storage tank, including wind resistant ring beams, locks, winding ladders, guardrails, etc. Its materials are generally low strength carbon structural steel, and other accessories and accessories are selected based on different uses.
