Storage Tanks, Uses and Properties

Tanks designed for water and liquid based storage. It is mostly used in the petroleum industry, but also in other sectors (food industry, fertilizer industry, etc.) are used.

The design and construction of storage tanks are carried out in accordance with international standards. The stored products are generally petroleum derivatives or chemicals used in the petroleum industry.

Carbon steel in the desired capacity, 304/304L quality, 316/316L quality productions are made in accordance with the standards.

Low pressure tanks

Designed and constructed according to API 620, the maximum working pressure of these tanks is 15lbf / in2 (103.4kPa).

Atmospheric tanks

Designed and constructed according to API 650, the working pressure of these tanks is the same as the atmospheric pressure (101,3kPa). For its design, the density of stored fluid, vapor pressure, etc. its properties should be known.

Mechanical calculations of tanks also depend on geographical features; soil structure for the foundation, wind forces for overturning safety, calculation of earthquake loads are considered.

Classification

Tanks can be classified according to roof constructions:

According to roof type (dome roof, conical roof, umbrella type roof)
According to floating ceiling type (internal floating ceiling, external floating ceiling)
Special tanks (double walled, underground tanks, insulated)

In addition, classifications can also be made according to the type of stored material, whether it is insulated or not, or its diameter.
