The screw-type air compressor unit itself is not classified as a special‑purpose device; however, the associated air receivers and pressure pipelines, when they meet specific parameter thresholds, are included in the catalog of special‑purpose equipment and subject to…
Pressure vessel
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…
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…
Air compressors are closely linked to environmental protection and safety. They can impact the environment through energy consumption, noise, leaks, and waste, while also posing risks related to pressure vessels, electrical safety, and maintenance standards. By selecting equipment…
Air receivers typically do not have a straightforward “shelf life”; instead, attention should be focused on their design service life, the status of periodic inspections, and their safety performance. Whether they can continue to be used should be…
