A106 grade B pipe API standard 650 floating-roof tanks

API standard 650 floating-roof tanks, Oil tanks can be divided into above ground storage tanks, underground storage tanks, offshore tanks and submarine tanks according to their installation positions. Oil tanks can be divided into crude oil tanks, fuel oil tanks, lubricating oil tanks, edible oil tanks, etc.. According to the use of oil tanks, oil tanks can be divided into production tanks, storage tanks, etc.. According to the external style, oil tanks can be divided into vertical tanks, horizontal tanks, etc.. According to the composition structure, oil tanks can be divided into fixed roof storage tank, floating roof tank, spherical tank, etc.

Density of API standard 650 floating-roof tanks Liquid Stored
The density of the liquid stored shall be its maximum density within the range of design temperatures, but no less than 29.3 lbf/ft3 for methane, 34.21 lbf/ft3 for ethane, and 35.5 lbf/ft3 for ethylene.
Design Metal Temperature
The design metal temperature of each component exposed to the liquid or vapor being stored shall be the lower of the temperatures specified as follows: The design metal temperature of the components of the API 620 single-wall tank or the inner tank of a double-wall tank shall be the minimum temperature to which the tank contents shall be refrigerated, including the effect of subcolony at reduced pressure.

The liquid level of API 650 oil storage tank is covered by floating roof. The storage liquid of API 650 oil storage API standard 650 floating-roof tanks tank is isolated from the air, reducing air pollution, fire and explosion hazards, and easy to ensure the quality of liquid storage. It is especially suitable for the API standard 650 floating-roof tanks storage of high-grade gasoline, jet fuel and toxic and easily polluted liquid chemicals.
