Materials used in the construction of API standard 650 self anchored flatbottom tanks

According to the structure type of floating roof, floating roof API standard 650 self anchored flatbottom tanks can be divided into internal floating roof tank and external floating roof storage tank. The internal floating roof tank is a floating roof tank with tank roof. The top is the combination of dome roof and floating roof, the external is dome roof, and the internal is floating roof. There is no vault on the top of the External floating roof tank, only a top plate floating with the storage liquid. The common feature of the inner floating roof tank and the outer floating roof tank is that both of them can reduce the evaporation loss of the storage liquid.

API 650 petroleum storage tank has the advantages of high safety: the API standard 650 self anchored flatbottom tanksinner floating plate floats on the liquid surface, so that the liquid phase has no evaporation space, which can reduce the evaporation loss by 85% to 90%. At the same time, the API 650 petroleum storage tank blocks the air and liquid storage through the floating disk, which reduces air pollution and reduces the degree of fire risk.

Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the API standard 650 self anchored flatbottom tanks steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its API standard 650 self anchored flatbottom tanks steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.
