3m diameter API standard 650 self-anchored tanks
The characteristics of the API standard 650 self-anchored 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 standard 650 self-anchored 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.
To scientifically evaluate the remaining service life of the API standard 650 self-anchored tanks, it is necessary to know the thickness change and development trend of the storage tank sheet after long-term use, combined with the metal characteristics of the storage tank, the influence of various external conditions and the continuous change of the oil pressure in the API standard 650 self-anchored tanks, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API standard 650 self-anchored tanks are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.
Data Required from Manufacturer on Completed TanksIf specified in the purchase order, the Manufacturer shall supply marked copies of plans (or a separate sketch) showing the location of all plates, with a means of identifying each plate with the heat numbers. These markings shall be checked by the inspector. A copy shall be attached to the Manufacturer’s report.Check of Stress-relieving OperationThe API standard 650 self-anchored tanks inspector shall check any thermal stress-relieving operation and shall be satisfied that the temperature readings are accurate and that the procedure conforms to the applicable requirements of these rules.
