The screw-type air compressor host is a power‑driven machine and is not itself a pressure vessel. However, its associated gas storage tank and certain internal components—such as the oil–gas separator vessel—are classified as pressure vessels under statutory regulations…

Screw-type air compressors are not, in and of themselves, equivalent to simple pressure vessels. The compressor unit itself is classified as compression‑driven equipment, whereas the associated air receiver tank can be designated a simple pressure vessel only when…
Air compressor surge tanks are generally classified as pressure vessels. This article provides a detailed analysis of the criteria for determining whether a surge tank qualifies as a pressure vessel, its classification and categorization, as well as the…
Whether an air compressor qualifies as a special‑purpose device cannot be determined solely on the basis of its name; it must be assessed in light of its design, pressure‑bearing parameters, intended use, and the applicable regulatory catalog of…
Whether an air compressor qualifies as a special‑purpose device cannot be determined solely by its name; it must be assessed in light of the equipment’s design, pressure ratings, volume, the medium it handles, and whether it is listed…
An air compressor is not necessarily a pressure vessel; the determining factors are whether it is equipped with pressure-bearing components such as an air receiver tank, and what its design pressure, volume, and applicable regulatory requirements are. In…
Whether an air‑compressor station dryer qualifies as special equipment cannot be determined solely on the basis of its name; it must be assessed in light of factors such as the equipment’s structure, pressure‑bearing status, design pressure, volume, and…
Whether an air compressor pipeline requires inspection and approval cannot be determined solely by its nominal diameter. Typically, this should be assessed in conjunction with the design pressure, process medium, operating temperature, intended application, and local regulations governing…
