Is the screw air compressor a pressure vessel?

Screw air compressor is a kind of air compressor, mainly used to provide compressed air. The pressure vessel is a closed device that can hold gas or liquid and carry a certain pressure. Although the screw air compressor will produce a certain pressure in the work, it is not used to contain gas or liquid, nor is it a closed equipment, so it does not belong to the pressure vessel.

In addition, there are also differences in safety requirements and regulatory standards between screw air compressors and pressure vessels. Pressure vessels need to meet higher safety standards and regulatory requirements due to their special working environment and bearing pressure requirements. Although the screw air compressor also needs to meet certain safety standards, its safety requirements and regulatory standards are relatively low.

Therefore, the screw air compressor does not belong to the pressure vessel, and the two are different in terms of definition, use, safety requirements and regulatory standards.
