The maximum design liquid level of API 650 mechanically-anchored flat-bottom tanks
BBN can provide design, manufacture and installation of API 650 large oil and crude oil storage tanks. We can build a API 650 mechanically-anchored flat-bottom tanks 7,000,000 gallon API 650 petroleum storage tank. In addition, BBN has the means to construct multiple storage tanks at the same time. We are very experienced in providing API 650 petroleum storage tanks.
The thickness of the API 650 mechanically-anchored flat-bottom tanks annular bottom plates shall be in accordance with Table Q-4 (for steel or aluminum, as applicable). The thicknesses shown are minimums. The ring of annual plates shall have a circular outside circumference, but it may have a regular polygonal shape inside the tank shell with the number of sides equal to the number of annular plates. These pieces shall be butt-welded in accordance with Q.7.1.1, Item b. The plates of the first shell course shall be attached to the annular bottom plates by a weld as required by API 620 oil tank 5.9.5 except when a full-penetration weld is used or required (see Q.7.1.1). Butt-welds in annular plates shall be not closer than 12 in. from any vertical weld.
Generally, external environment corrosion should be considered before design and construction of API 650 mechanically-anchored flat-bottom tanks and so on storage tanks. The corrosion on the outer surface of storage tank is often worse than that on the inner surface. Especially in the chemical industry area, there are often acid fog, alkali or salt dust in the atmosphere. These impurities form an active corrosive medium with dew or steam and oxygen in the atmosphere. The corrosion of the external environment of the storage tank shortens the maintenance period of the storage tank, even causes the storage tank to be scrapped in advance, which affects the normal operation of the storage and transportation.
