Foundation loading data of API Std 650 welded steel oil storage tanks

The water dissolved in the oil will be separated out from the oil stored in the API Std 650 welded steel oil storage tanks for a long time, and the acidic water layer will appear at the bottom of the API Std 650 welded steel oil storage tanks for a long time, which will accelerate the corrosion of the API Std 650 welded steel oil storage tanks and cause the wall thinning and even leakage. With the increase of service life, the API Std 650 welded steel oil storage tanks must be inspected and cleaned regularly to check the hidden danger.

Density of API Std 650 welded steel oil storage 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.

These API 650 documents will define the bases of design, operation, inspection, tests, examinations, and maintenance of an API Std 650 welded steel oil storage tanks industrial facility. Bidders will study and analyze all this API 650 documentation, both during the preparation of the quotation and during the execution of each project activity.
