Vertical Steel Tank Vol.400 cbm (AST-400)

Content:
  • Loading capacity: 400m³
  • Diameter: 8,53m
  • Height: 7,5m
  • Net weight ≈ 19t
  • Coils: 1

A steel Above-ground storage tank of 400 cubic meters (AST-400) is designed to store various liquid products, including hazardous ones.

We offer you to fabricate the metal structures of the AST-400 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-400 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 400 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-400 - Storage Tank RoofAST-400 Roof

In tanks with a volume of 400m³ roofs of various types can be used. The most common are frameless conical covering (self-supporting roof), frame conical roofs with decking and shield roofs.

Frameless covering can be used in tanks of loading capacity up to 1000m³. Its bearing capacity is provided by a conical shape. The taper angle can be from 15 ° to 30 °. Roof plates are welded with double-sided butt welds.

A conical frame roof is used for vertical tanks with a volume of up to 5000m³. Such a roof consists of frame elements, a central ring and flooring plates.

The shield roof is assembled of shop-welded framed segments (shields).

 

 

Internal Floating Roof for a Vertical 400 m³ Steel Tank

The AST-400 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.

There are certain ways to optimize your order for a vertical 400 m³ steel tank:

  • Look through the production versions of our vertical tanks.
  • Make your enquiries at the initial planning stages – to get free consultant advice, calculations, information materials from our specialists.
  • Save money and ensure quality – order everything from one contractor. We bear full responsibility for your tank from the planning stage to the star-up on turnkey basis. In this case we will be able to reduce material cost, make the delivery logistics cheaper, provide fast and quality installation of our metal frameworks and ensure perfect set of documents.
  • You can receive full information on engineering design, construction unique features, production technologies, installation and service for the vertical tanks on our web-site.
