Does the air tank on the air compressor belong to the pressure vessel?

The air tank on the air compressor belongs to the pressure vessel.

According to the Regulations on Safety Supervision of Special Equipment, a pressure vessel is a closed device that contains gas or liquid and carries a certain pressure. The scope is defined as fixed containers and mobile containers for gases with a maximum working pressure greater than or equal to 0.1MPa (gauge pressure), liquefied gases and liquids with a maximum working temperature greater than or equal to the standard boiling point. Since the air compressor storage tank needs to withstand the pressure of the internal gas and maintain its air tightness, it meets the definition of a pressure vessel.

Air compressor storage tanks are widely used in industrial production to store compressed air. Because it stores compressed gas inside, it must be able to withstand the corresponding pressure. This characteristic makes the air compressor tank classified as a pressure vessel.

In summary, the air tank on the air compressor is indeed a pressure vessel. During use, the relevant safety regulations and operating procedures should be strictly observed to ensure its safe operation.
