Scope

This standard specifies the manufacturing requirements for underground horizontal circular single-layer and double-layer storage tanks for storing flammable and non-flammable liquids that pollute water within the following scope. ——The nominal diameter of the tank is 800mm~3000mm; 　——The total length of the tank does not exceed 6 times the nominal diameter; 　——The maximum density of the liquid stored is 1.9g/mL; 　——The maximum working pressure (P: 0.15MPa (gauge pressure) )); 　——For double-layer storage tanks using vacuum leakage detection systems, the dynamic viscosity of the liquid stored should be ≤5×10m/s. This standard applies to storage tanks under normal temperature (-20°C ~ +50°C) conditions. If the operating temperature of the storage tank exceeds this range, additional requirements should be considered. See Appendix B for the stored liquid-steel combination. This standard does not apply to the storage of liquids with special hazards described in Table 1. This standard does not cover internal coatings of storage tanks. Brief table
