For storage tanks of categories A and B with the same volume, is it better to have a larger height-to-diameter ratio or a smaller one? What potential risks might arise from making it taller considering factors such as floor space and safety?
The design diameter and height are determined based on the requirements of the construction party regarding the tank capacity, as well as rational considerations for diameter and height. For storage tanks of generally small to medium capacity (3000 m3 or less), the height-to-diameter ratio of the tank is determined based on the principle of using as little material as possible, with this ratio being around 1 ； The height-to-diameter ratio of medium to large capacity storage tanks (3000 to 10,000 m3) is 0.7 to 0.5. The larger the capacity, the smaller the height-to-diameter ratio. All of the above are short and stout-shaped storage tanks. As the national economy continues to develop, construction companies are showing great interest in slender oil tanks with a high length-to-diameter ratio. What is a reasonable height-to-diameter ratio? Neither standard GBJ 128 nor SH 3046 addresses this issue; in practical design, the height-to-diameter ratio is generally kept below 1.65.
In practical design, the height-to-diameter ratio is generally kept below 1.65. Where does this value of 1.65 come from?
In terms of cost, slender ones are better!
The cylinder is tall and slender, with both the cylinder wall and the head thickness significantly reduced!
But won’t the number of welds on the cylinder body increase significantly, and will the labor costs be higher?
The higher the tank, the greater the required safety distance from adjacent storage tanks; it seems that GB50160 contains such a provision.
It’s too high; the static pressure increases, and in the event of a leak, the spray will be intense as well. It is not necessarily material-saving; the height-to-diameter ratio is close to 1, and the shape is close to spherical
The height of the storage tank determines its distance from the cofferdam, while the diameter determines its distance from adjacent storage tanks; therefore, a comprehensive consideration is necessary.
