A678 grade A plates API 650 aboveground welded storage tanks

The advantages of API 650 floating roof tanks have obvious environmental and economic benefits: in a specific climate environment, according to historical data, the economic value of the API 650 aboveground welded storage tanks floating roof tanks in API 650 due to the reduction of oil and gas volatilization within 3-6 months is equivalent The installation and purchase cost of the API 650 aboveground welded storage tanks inner floating roof means that the cost of the inner floating roof can be recovered within half a year.

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.

There is no dome roof in the top of the vertical external floating roof oil storage tank, only the disc floating roof which can float up and down. The wall plates are connected by butt welding, and the construction is usually carried out by the forward installation method, and the storage capacity is usually more than 10000 cubic meters. Vertical internal floating roof API 650 aboveground welded storage tanks has both dome roof and internal floating roof. The internal floating roof floats on the liquid surface inside the dome roof oil tank and can float up and down. The storage capacity is usually between 1000 and 10000 cubic meters.
