vertical steel tank 50000

TECHNICAL SPECIFICATIONS OF RVSPK-50000M3 TANK

*Overall dimensions are for reference and may vary depending on Customer requirements

RVSPK 50000 M3 TANK COMPLETE SET:

- shaft or straight-flight ladder (upon request),

- annular service platform - 1 set,

- equipment (hatches, nozzles) – 1 set.

Upon Customer request, we produce vertical tanks with a volume of 50000 m3 with thermal insulation or a heater (sectional or heat exchange jacket), which help maintain a given temperature.

If it is necessary to increase the service life of the tank and/or store aggressive liquids, the designer can include a corrosion allowance for the tank structures.

RVSPK-50000 M3 DRAWING

Drawing of the RVSPK-50000 vertical tank structure

1 - shell, 2 - bottom, 3 - roof, 4 - hatches and nozzles in the shell and roof, 5 - spiral staircase, 6 - platforms and railings on the roof, 7 - grounding attachment.

The shell, roof, and bottom are produced from rectangular steel sheets. The size of the sheets used depends on the element, for example, for the cylindrical shell, panels up to 1.5x6.0 m are taken. The used steel sheets are then welded into panels and coiled on a rolling stand.

RVSPK-50000 tanks use a **double-deck floating roof**. Double-deck floating roofs are designed for larger diameter tanks (over 50 m) and for areas with higher wind loads. Their design allows for reducing dynamic loads on the membrane. There are two options for constructing a floating roof of this design:

1. the roof is equipped with radial compartments and annular compartments of the central part, formed during installation;

    

2. radial boxes are manufactured in the factory to reduce the volume of installation work.

    

During the installation of the floating roof, the membrane is sloped towards the center by ballasting. This allows for the drainage of rainwater from the roof surface. A flexible or articulated drain is installed in the center, equipped with an intake device and a check valve. This design allows for water drainage and, at the same time, prevents the stored product from surfacing on the roof.

The bottom is a flat structure, consisting of steel sheets welded into a panel of the required size (depending on the volume).

RVSPK-50000 m3 tanks with a pontoon or floating roof are more reliable constructions: they prevent the evaporation of stored liquid into the atmosphere. However, they must be operated without pressure and without vacuum.

A protective wall also prevents the stored product from entering the environment in case of leakage.

Integral structural elements are ladders and platforms with or without railings, necessary for personnel access.

In the body and roof at the design stage, and then during manufacturing, hatches and nozzles are provided for the installation of technological equipment (receiving-dispensing equipment, level control devices, etc.). For this purpose, NTKOILSERVICE factory provides for the production of technological tank equipment, which includes loading/unloading devices, nozzles, hatches, equipment for measuring the level of stored liquid.
