Options for the HST-20 fabrication
Single-skinned / Double-skinned variant:
Horizontal tanks can be double-skinned (double-walled) and single skinned (single-walled).
As a rule, singe skinned tanks are used to store non-aggressive and environmentally friendly liquids. Double skinned tanks - for oil, oil products and hazardous chemical liquids.
In the course of production of a double-skinned tank the space between the walls is filled with either nitrogen or liquid material. The space is filled to its full volume and the tank is equipped with the system of hermetical pumpout.
Requirements for the filler liquid material:
- Flash point not lower than 100°С;
- Resistance to chemicals, used in tank scheme, and the stored product;
- Mass density, exceeding that of the stored product;
- Ability to keep properties at the external temperatures, which the tank is meant to be used at.
Single-section / Two-section / Multi-section variant:
All above-mentioned versions of horizontal tanks may be produced with either one or several sections. The sections are formed by special separating walls inside the body of the tank. Thus the horizontal tank becomes divided into two or more sections, meant for storing different types of materials. While producing two-section or multi-section tanks we guarantee the leak tightness of the sections.
