Vertical Steel Tank Vol.20000 cbm (AST-20000)

Content:
  • Loading capacity: 20000m³
  • Diameter: 39,9m
  • Height: 17,8m
  • Net weight ≈ 432,7t

A steel Above-ground storage tank of 20000 cubic meters (AST-20000) is designed to store various liquid products, including hazardous ones.

We offer you to fabricate the metal structures of the AST-20000 tank in our modern specialized workshop, deliver them to your construction site, assemble them and commission the tank.

For the proper storage of your product in the tank, we will select the optimal internal anti-corrosion coating.

On this page AST-20000 of our standard design is proposed. For each customer, the design of the tank is being finalized or a completely individual design is being made.

If this tank interests you, you can download, fill out and send us a Data sheet. Then we can do all the calculations and prepare for you a detailed commercial offer.

The above-ground storage steel tank with a loading capacity 20000 m³ can be designed, fabricated and constructed using the plate-by-plate method, traditional for Europe and US. At the same time, our factory is equipped with a special coiling machine, so we can fabricate tanks using the coiling method, which is widely used in Russia and the CIS countries.

AST-20000 - Storage Tank Fixed RoofAST-20000 Roof

In tanks with a volume of more than 10,000 m³, as a rule, 2 types of roofs are used: a fixed spherical frame roof or an external floating roof.

In the picture you can see the fixed roof. It is a sphere with a radial-ring frame system. The radius of the sphere is projected within 0.8 - 1.5 diameters of the tank itself.

The roof of the AST-20000 consists of a central shield, rolled radial beams, ring frame elements, a stiffening ring around the perimeter of the shell and decking plates.

 

 

Internal Floating Roof for a Vertical 20000 m³ Steel Tank

The AST-20000 tank for storing easily evaporating (volatile) liquids can be equipped with an internal floating roof.

Evaporation resulting from small and large "breathing" of the tank leads to significant money losses, the quality of the product decreases and the environment deteriorates. An internal floating roof helps solve these problems effectively.

Most often, aluminum internal floating roofs of block or pontoon type are used.

The design of the block floating roof that we manufacture consists of sealed aluminum blocks with dimensions of 2.98x0.89x0.04 m. The blocks are filled with rigid polyurethane foam.

Pontoon floating roof is a disk with the diameter less than the tanks’ diameter by 0.4 m, mounted on cylindrical flotation pontoons . Pontoons provide buoyancy of the roof on the surface of the product. Immersion of the floats occurs only on ½ of their diameter, as a result of which free space is formed between the deck and the surface of the liquid. The space is filled with product evaporation. To prevent vapor leakage, the roof around the perimeter is equipped with a special elastic shutter.
