Underground Drainage Tanks

General features

EuroTankWorks produces underground drainage tanks with and without heating-up.

The underground drainage tanks are used for storing the residues of hazardous liquid products and oil products (both light and dark) discarded from the technological pipelines. These tanks are widely applied at Russian enterprises because almost every production facility faces the necessity to discard the rest of fluid products, used in the technology cycle.

You can choose for yourself a drainage tank of suitable capacity from our standard designs, or order us an individual design.

Manufacturing of a tank is carried out in 4 stages

ENGINEERING DESIGN

For all drainage tanks in our Design office we have got detailed metal framework graphical drafts already done. Herewith they always will be finalized according to requirements of the Customer.

ASSEMBLING

We assemble the tank elements (pre-rolled shells and spherical bottoms) using the columned welding keys in automatic regime. All welds are performed back to back.

PAINTING

Applying coating is carried out with preliminary bead blasting processing, degreasing an dust removal. The coated units are dried in special premises, where the temperature, humidity and dust content are strictly controlled.

DELIVERY

Delivery is carried out by means of motor or railway transport.

A drainage tank (underground) is an all-welded horizontal steel tank with conical bottoms and manway plates. The latter are used for product’s pumping out of the tank (with a bottom hole pump) as well as for tank service operations.

We manufacture oily effluent tanks in several construction versions:

drainage storage tank without heating-up;
drainage storage tank with heating-up system in the form of metal heating spiral (helicoil) or heating cable;
Climate versions: Т4 (not lower than – 20 °С); У0 (not lower than – 40 °С); HL (– 60 °С at the lowest).
Nominal volume (loading capacity) from 5 m³ to 63 m³
Tanks can be equipped by heat insulation.

General Features of Underground Oily Effluent Tanks:

Drainage tanks (underground) are used for storing products of 2nd to 4th danger class;
The tanks are meant for the stored product’s temperature limits from -15°С to +80°С;
The oily effluent tanks stand the inside pressure up to 0,07 mPa;
Kinematic viscosity coefficient of the discarded product should not exceed 30•10-6 m²/s;
Mass density of the product, discarded to the tank, must not exceed 1000 kg/m³;

We recommend to order tanks with inner and outer corrosion preventive coating so as to make their operating life longer. The coating characteristics are chosen on the basis of specific features of the discarded product and the operating regime.
