A285 Gr C plates API 650 open-top tanks

The characteristics of the API 650 open-top tanks internal floating roof structure of API 650 petroleum storage tanks: the inner floating roof or inner floating plate refers to the floating roof that floats on the liquid surface of the oil tank with the oil and liquid up and down. The API 650 open-top tanks inner floating roof is used to cover the liquid. The surface is currently recognized as the most ideal and most economical and practical way to reduce oil evaporation loss.

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

Investigation of Subgrade
On actual steel storage tank sites to be used, test borings or test pits, or both, may be made at the direction of a competent engineer who will specify the number and location. They need not be equally spaced but should be laid out to uncover possible weak spots.
In general, test loadings of subgrade at the bottom of test pits need be resorted to only when such heavy loading as may be imposed by footings for major column supports for spheres or similarly elevated API 620 low-pressure tanks is specified. Results may be deceptive if average load-bearing capacity over a considerable area is wanted. All field data shall be recorded with maps, and copies shall be supplied to all engineers concerned with design, erection, and later operation.
