API Std 650 ground-supported liquid storage tanks of relatively small capacity

Volatilization is the characteristic of oil. Under normal temperature and pressure, as long as the oil is in contact with air, the surface will volatilize. Through scientific analysis and summary, the causes of oil volatilization loss in API Std 650 ground-supported liquid storage tanks are: natural ventilation loss, static storage loss, dynamic liquid level loss. In the use of API Std 650 ground-supported liquid storage tanks, static storage loss and dynamic liquid level loss are common losses.

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 Std 650 ground-supported liquid storage 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.

The Standard has gained international recognition and is the standard of choice of most builders of large liquid above ground API Std 650 ground-supported liquid storage tanks storage tanks. One reason for this is that the API 650 Standard was created and is revised by API committees comprised of the world s best tank structural engineers who also rely on the experience of tank owners and tank construction companies.

we develop very well through those years even the external environment is not conducive to the whole steel industry.
