A516 Gr 70 plates API Std 650 flat-bottom oil storage tanks

Usually, the soil resistance of the foundation should be considered before the design and construction of API Std 650 flat-bottom oil storage tanks. The soil endurance in the API Std 650 flat-bottom oil storage tanks construction area plays a decisive role in the basic cost of the tank. In areas with high soil resistance, not only the cost of foundation treatment can be greatly reduced, but also the ratio of height to diameter of storage tank can be obtained. Therefore, the investment cost of the API Std 650 flat-bottom oil storage tanks can be greatly saved in the area with large soil resistance.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 a gap of 100 mm to 500 mm between the shell of API 650 crude oil storage API Std 650 flat-bottom oil storage tanks tank and the floating plate of external floating roof to ensure that there is no chuck during operation. Use API Std 650 flat-bottom oil storage tanks edge sealing system to reduce edge evaporation. The support legs of API 650 crude oil tank floating roof are usually movable and retractable and suspended in liquid.Insist on the spirit of development and indomitable entrepreneurship; the spirit of leading science and technology and striving for first-class affairs; the spirit of strict management and market development; the spirit of taking the lead in setting an example and selfless dedication; and the spirit of people-oriented and enterprise ownership.We have a professional production team and high-quality production equipment, and we also have a great API Std 650 flat-bottom oil storage tanks advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the API Std 650 flat-bottom oil storage tanks production of high-quality steel plates, steel pipes and other products that meet customer requirements.
