The classification of pressure vessels in screw air compressor oil–gas separators has long been a subject of close attention. This article clarifies the criteria for defining simple pressure vessels, examines the differences in regulatory classification between small and…
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…
Simple pressure vessels used in compressor rooms are not required by law to undergo periodic inspections of the vessel body during their design service life (typically 10 years). However, the user organization must conduct routine inspections and verify…
