Does the air compressor itself qualify as special equipment?
When examining specialized equipment within air compressor systems, the first thing that needs to be clarified is,The air compressor host itself is not classified as special equipment.As a power‑generating device that converts mechanical energy into pneumatic pressure, the air compressor is designed and manufactured in accordance with general mechanical product standards and does not fall under the direct jurisdiction of special equipment safety regulations.
Special equipment in the compressed air system: air receiver tank
Although the air compressor host is not a special‑type piece of equipment, the auxiliary components used in conjunction with it…Gas storage tanks are generally classified as special equipment.. In the catalog of special equipment, gas storage tanks are classified as “pressure vessels.” When a gas storage tank’s maximum working pressure, volume, and the properties of its contained medium meet the criteria stipulated in the relevant national safety technical regulations for special equipment, it must be included in the scope of special‑equipment management.
- Fixed pressure vesselCommonly used vertical or horizontal gas storage tanks are employed to store compressed air and stabilize pipeline pressure.
- Simple pressure vesselSome gas storage tanks with smaller volumes and lower design parameters may qualify as simple pressure vessels. Such equipment is granted certain exemptions from registration and inspection requirements, but it must still comply with applicable safety standards.
Special Equipment in Air Compressor Systems: Pressure Piping
In addition to the air receiver tank, the components in an air-compressor system used to convey compressed air are…Pressure pipelines are also classified as special equipment when they meet specified conditions.A pressure piping system is a tubular device that uses a specified pressure to convey gases or liquids. When the pipeline’s maximum working pressure, nominal diameter, and transported medium—among other parameters—reach the statutory threshold values, it falls under the regulatory oversight for special equipment. Enterprises must ensure that the design, installation, and routine maintenance of such pipelines comply with applicable safety standards.
Compliance Management Requirements for Special Equipment
For gas storage tanks and pressure pipelines subject to special equipment management, the user shall strictly comply with relevant laws and regulations and fulfill its primary responsibility for safety. The principal compliance requirements include:
- Registration for UseSpecial equipment shall, before being put into service or within the prescribed time limit after being put into service, be registered with the relevant authorities and obtain a certificate of use registration.
- Periodic inspection: In accordance with the requirements of safety technical specifications, a request for periodic inspection must be submitted to a special equipment inspection agency prior to the expiration of the inspection validity period. Equipment shall not be put into service if it has not been inspected or if it fails the inspection.
- Personnel QualificationsPersonnel responsible for the safety management of special equipment and operators must obtain the requisite qualifications in accordance with relevant national regulations before they may engage in related work.
- Routine maintenance and repairEstablish safety technical files for special equipment, conduct routine daily maintenance and upkeep, and perform regular self-inspections.
