tankThe steel sealed containers mainly used for storing liquids or gases are steel storage tanks. Anti corrosion storage tank engineering is an important infrastructure in industries such as petroleum, chemical, grain and oil, food, fire protection, transportation, metallurgy, and national defense. Our economic life always relies on large and small steel storage tanks. The important role of anti-corrosion storage tanks in the development of the national economy is crucial. Steel storage tanks are equipment for storing various liquid (or gas) raw materials and finished products. For many enterprises, normal production cannot be achieved without storage tanks, especially for national strategic material reserves, which rely on various capacity and types of anti-corrosion storage tanks and other storage tanks. Our country's oil storage facilities are mainly composed of above ground storage tanks, and are mostly made of metal structures. Therefore, this article will focus on introducing some basic knowledge of dome roof storage tanks, internal floating roof storage tanks, horizontal storage tanks, and anti-corrosion storage tanks commonly used in China.
　　
Due to the different storage media, there are also various forms of storage tanks.
　　
Classified by location: can be divided into aboveground storage tanks, underground storage tanks, semi underground storage tanks, offshore storage tanks, underwater storage tanks, etc.
　　
Classified by oil products: can be divided into crude oil storage tanks, fuel oil storage tanks, lubricating oil tanks, edible oil tanks, fire water tanks, etc.
　　
Classified by purpose: can be divided into production oil tanks, storage oil tanks, etc.
　　
Classified by form: can be divided into vertical storage tanksHorizontal storage tankWait.
　　
Classified by structure: can be divided into fixed roof storage tanks, floating roof storage tanks, spherical storage tanks, etc.
　　
Classified by size: Large storage tanks with a capacity of over 100m3 are mostly vertical tanks; Storage tanks below 100m3 are small and mostly horizontal.
　　
According to the material of the storage tank: The materials required for storage tank engineering are divided into tank body materials and ancillary facility materials. Tank materials can be divided into low strength steel and high strength steel according to their tensile yield strength or tensile standard strength. High strength steel is mostly used for storage tanks with a capacity of over 5000m3; The ancillary facilities (including wind resistant ring beams, locking ports, spiral ladders, guardrails, etc.) are made of ordinary carbon structural steel with lower strength, while other accessories and attachments are made of other materials according to different purposes. The commonly used domestic steel for manufacturing tanks includes 20, 20R, 16Mn, 16MnR, and Q235 series.
