Pressure vessel

An air compressor is, by its nature, a device for compressing air and should not be equated with a pressure vessel. Whether it qualifies as a pressure vessel depends on the design pressure, volume, working medium, and applicable…

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 design service life of air compressor receiver tanks typically ranges from 7 to 10 years, but the actual safe operating lifespan is influenced by a variety of factors, including material quality, operating environment, routine maintenance, and periodic…

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…

The core vessel that typically accompanies an air compressor is commonly referred to as an air receiver tank. It not only serves as a storage unit for compressed air but also plays a critical role in pressure stabilization,…

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…
