2. Fire-fighting CO for oil depot and petrochemical plant₂The radius and height size of the gas storage tank _ spherical tank body structure recommend the design range: the radius SR is 1/4-1D, the height is less than or equal to 1H, and the optimal value is as follows: radius SR ═ 1D, height 1H, as shown in figure 2 of the accompanying drawings.

3. The spherical tank body is spherical and is formed by splicing and welding steel plates, and the thickness size recommends the design range: 6mm to 18mm, as shown in figures 2, 3, 4, 5, 6 and 7 of the accompanying drawings.

4. The inner supports of the cylindrical pipe are uniformly arranged in the radius direction of the spherical tank and are welded with the spherical center ball body and the tank body into a whole, and the recommended design range of the wall thickness of the cylindrical pipe is 6mm to 20mm, as shown in attached figures 2, 3, 4 and 9.

5. The size of the sphere center sphere radius SR is recommended to be designed in a range of 400mm to 1000mm, and the thickness size is recommended to be designed in a range of 6mm to 20mm, as shown in the attached figures 2, 3, 4 and 10.

6. A plurality of air inlet and outlet pipes can be arranged in the diameter size recommended design range of 200 mm-1000 mm and the wall thickness size recommended design range of 6 mm-20 mm, as shown in attached figures 2, 4, 5, 6 and 8.

7. The spherical tank is integrally located on the spherical tank base and the circular pipe support, the recommended design range of the thickness and the size of the base steel plate is 20mm to 40mm, the recommended design range of the circular pipe wall thickness and the size of the support circular pipe is 12mm to 20mm, and the spherical tank is welded firmly, as shown in fig. 2 and 11.
