80ft diameter API standard 650 cylindrical liquid-storage tank

The floating roof is the top cover floating on the liquid level, so the sealing performance of API standard 650 cylindrical liquid-storage tank API 650 oil storage tank is very important. The floating plate mainly adopts elastic packing, and at the same time, it is compressed with the wall of API 650 oil storage tank with pressure strip around, and fixed with the floating plate with bolts. After the API standard 650 cylindrical liquid-storage tank floating plate is lowered to a certain position of about 1.8m, a prop will support the floating plate to keep it in position.

Generally, external environment corrosion should be considered before design and construction of API standard 650 cylindrical liquid-storage tank 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.
