The safety status classification of an air storage tank is related to its design pressure and volume. Generally, air storage tanks are classified into the following four levels:
1. Tanks for key enterprises: Design pressure less than 0.1 MPa, volume less than or equal to 10 m³;
2. Tanks for general enterprises: Design pressure less than 0.1 MPa, volume greater than 10 m³;
3. Tanks for key enterprises: Design pressure greater than 0.1 MPa, volume less than or equal to 10 m³;
4. Tanks for general enterprises: Design pressure greater than 0.1 MPa, volume greater than 10 m³.
Based on the safety status classification of the air storage tank, different levels of tanks must comply with corresponding safety regulations during use.
