Frangible roof API standard 650 carbon and low-alloy steel tanks

There is no dome roof in the top of the vertical external floating roof oil storage tank, only the disc floating roof which can float up and down. The wall plates are connected by butt welding, and the construction is usually carried out by the forward installation method, and the storage capacity is usually more than 10000 cubic meters. Vertical internal floating roof API standard 650 carbon and low-alloy steel tanks has both dome roof and internal floating roof. The internal floating roof floats on the liquid surface inside the dome roof oil tank and can float up and down. The storage capacity is usually between 1000 and 10000 cubic meters.

Foundations and subgrade shall safely carry the weight of the tank API standard 650 carbon and low-alloy steel tanks and its contents when the tank is filled with water to the highest level required for a hydrostatic test or other water-loading operations, even though the tank itself may be designed for some lesser density of liquid. However, in cases where the character of the soil justifies it and a competent soil expert advises it, allowance may be made for the relatively short duration and intermittent nature of the water loadings if suitable account is taken of all such loadings that may be expected to occur during the life of the tank, including not only those loadings that are incidental to periodic repetitions of the hydrostatic test in accordance with 7.18 but also water-filling operations for gas-freeing purposes.

Application scope of API 650 petroleum storage tank:
1. API standard 650 carbon and low-alloy steel tanks Working pressure: atmospheric storage tank;
