Marking of underground drainage storage tanks:
Marking of underground drainage storage tanks for order purposes includes the type, loading capacity, inner diameter and the material of production.
An example of order form is as follows:
Underground Drainage Storage Tanks (Underground Drainage Storage Tanks with Heating-up) 25-2000-1-1(2)(3)-K, which stands for:
«25» – nominal volume in m³;
«2000» – inner diameter of the tank, mm;
«1» – construction specific features;
«1», «2» or «3» – material of production («1» – steel St3sp4 Russian State Standard GOST 380-90; «2» — steel 16GS Russian State Standard GOST 5520-79; «3» — steel 09G2S Russian State Standard GOST 5520-79);
«K» — concrete pit availability.
Application of drainage storage tanks:
The underground tanks are used for storing the rest of 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.
Tanks are meant for storing fluid products, containing not more than 1.8 % of hydrogen disulfide in gas phase.
