Is the air storage tank special equipment?

Whether the air storage tank belongs to special equipment needs to be comprehensively determined based on its design parameters and use scenarios. The details are as follows:

1. Definition basis for special equipment

According to the “Special Equipment Safety Law of the People’s Republic of China” and the “Safety Technical Supervision Regulations for Fixed Pressure Vessels”, if a gas storage tank meets the following conditions at the same time, it belongs to a “pressure vessel” in special equipment:

• design pressure: ≥0.1 MPa (MPa, about 1 kg pressure);
• volume: ≥0.03 cubic meters (about 30 liters) and internal diameter ≥150 mm;
• medium: Store gas (such as compressed air) or liquid with a maximum operating temperature ≥ standard boiling point.

2. Enterprise determination method

• View nameplate parameters: The gas storage tank body is usually marked with key data such as design pressure and volume, and enterprises can make preliminary judgments through the nameplate information.
• Consult supplier or inspection agency: If the parameters are close to critical values (such as design pressure of 0.1MPa and volume of 0.03 cubic meters), it is recommended to contact the supplier or professional inspection agency for confirmation.

3. Differences in management requirements

• If it belongs to special equipment: It needs to register with the local special equipment safety supervision and management department and accept regular inspections (generally 3-6 years/time). Operators need to hold certificates.
• If it is not special equipment: Management according to ordinary equipment, but still need to abide by safety operation specifications and regularly check tightness, corrosion, etc.

4. recommended practices

Enterprises should establish a gas tank ledger to record design parameters, inspection dates and other information. For gas tanks with critical parameters or complex operating environments, it is recommended to manage them according to special equipment standards to reduce safety risks.

summary: Whether the air storage tank is a special equipment depends on its design pressure, volume and medium. Enterprises need to clarify management requirements through parameter verification to ensure compliance with regulations.
