輕質油料的儲罐过去一直是用鋼板制成的,但經过多年的实践証明,鋼板並不是儲存輕质油料最理想的材料。鋼板容易被油料中的硫分、水分和一些其他成分所腐蝕,被腐蝕下来的鉄銹、斑皮大量沉淀在油罐底部,使油料中的机械杂質增加,引起油料質量的变化。鋼板油罐另外一个缺点就是厚度薄,热的传导性大,油料中的輕餾分非常容易揮发。油料損耗大。所以有的油庫設計不得不在鋼板外部做上一层混凝土的保护层,但造价較高,頗不經济。
In the past, light oil storage tanks were made of steel plate, but after many years of experience, steel plates are not the ideal material for storing light oil. Steel is easily corroded by the sulfur, moisture and some other components in the oil. The rust that is corroded is greatly precipitated on the bottom of the tank, causing the mechanical impurities in the oil to increase, causing the quality of the oil to change. Another disadvantage of steel plate tanks is their thinness and large thermal conductivity. The light fractions in the oil are very volatile. Large loss of fuel. Therefore, some oil depot design had to do a layer of concrete protective layer on the outside of the steel plate, but the cost is high and it is not economical.
