API 650 mechanically-anchored tanks bottom-transition plate

No matter what type of storage tank needs to be built, the natural conditions of the geographical area where the tank is located should be fully considered in the design. Because natural conditions will affect the service life, storage safety and construction cost of storage tanks such as API 650 mechanically-anchored tanks. Generally, the natural conditions that need to be considered before API 650 mechanically-anchored tanks design and construction are: regional temperature, wind load, snow load, ground endurance, external environment corrosion, etc.

Allowable compressive stresses shall be in accordance with 5.5.4 except that for aluminum alloy plate the allowable compressive stresses shall be reduced by the ratio of the modulus of compressive elasticity to 29,000 for values of (t – c)/R less than 0.0175 and by the ratio of the minimum yield strength for the aluminum alloy in question to 30,000 for values of (t – c)/R equal to or greater than 0.0175 (see 5.5.2 for definitions). In all other equations in this standard API 650 mechanically-anchored tanks where yield strength or modulus of elasticity is used, such as Equations 27 and 28, similar corrections shall be made for aluminum alloys.

The floating roof is the top cover floating on the liquid level, so the sealing performance of API 650 mechanically-anchored tanks 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 650 mechanically-anchored tanks floating plate is lowered to a certain position of about 1.8m, a prop will support the floating plate to keep it in position.
