Whether the gas tank belongs to special equipment shall be comprehensively determined according to its design parameters and application scenarios. The details are as follows:
1.Basis for definition of special equipment
according to the “the People’s Republic of China Special Equipment Safety Law” and “Fixed Pressure Vessel Safety Technology Supervision Regulations”, if the gas storage tank meets the following conditions at the same time, it is a “pressure vessel” in special equipment “:
- design pressure: ≥ 0.1 MPa (MPa, about 1kg pressure);
- volume: ≥ 0.03 cubic meters (about 30 liters), and the inner diameter ≥ 150mm;
- medium: Stored gas (such as compressed air) or liquid with maximum operating temperature ≥ standard boiling point.
2.enterprise judgment method
- view nameplate parameters: The body of the gas storage tank is usually marked with key data such as design pressure and volume, and the enterprise can make a preliminary judgment through the nameplate information.
- Consult with suppliers or inspection agencies: If the parameter is close to the critical value (e. g. design pressure 0. 1MPa, volume 0.03 cubic meters), it is recommended to contact suppliers or professional inspection institutions for confirmation.
3.Management Requirements Variance
- if it belongs to special equipmentregistration with local special equipment safety supervision and management department, regular inspection (generally 3-6 years/time) is required, and operators are required to work with certificates.
- If it is not special equipment: According to ordinary equipment management, but still need to comply with the safety operation specifications, regular inspection of sealing, corrosion, etc.
4.Suggested measures
enterprises should establish a gas tank ledger, record design parameters, inspection date and other information. For gas storage tanks with critical parameters or complex use environment, it is recommended to manage them according to special equipment standards to reduce safety risks.
Summary: Whether the gas 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.
