Special equipment

Compressor rooms play a critical role in industrial production, and whether the equipment inside them qualifies as pressure vessels is a key safety concern for enterprises. This article examines common pressure‑vessel‑type equipment found in compressor rooms, such as…

The air compressor unit itself is not classified as a special‑purpose device; only the associated gas storage tank falls under the regulatory scope for special equipment. According to relevant safety technical standards, when the maximum working pressure of…

Do safety valves for air compressors require testing in foreign markets? The answer is yes. Whether it’s pre‑export certification or periodic verification after commissioning, major markets such as Europe and the United States impose stringent regulatory requirements. This…

The air compressor unit itself is not classified as a special‑purpose device; however, its associated gas storage tank, if it meets specific pressure and volume criteria, falls under the regulatory scope of special‑purpose equipment. This article provides a…

Whether an externally connected air tank for an air compressor qualifies as a pressure vessel depends primarily on its working pressure, volume, and the nature of the contained medium. Typically, industrial air receivers that meet criteria such as…

The primary subject of air compressor registration is, in fact, the air receiver tank, rather than the compressor unit itself. Air compressors are classified as general-purpose machinery, whereas air receiver tanks, as pressure vessels, are subject to stringent…

Although air compressors and pressure vessels are often used together in industrial settings, they are not the same thing. An air compressor is a power‑driven device that generates compressed air, whereas a pressure vessel is a sealed container…

Many companies, when purchasing air compressors, often wonder whether they qualify as special‑purpose equipment. In fact, the compressor unit itself is not classified as such; regulatory oversight primarily focuses on the associated air receiver tank. This article provides…
