This paper examines whether a 0.8 MPa gas storage tank can be connected to its safety valve using galvanized steel piping. It analyzes the pressure-bearing capacity of galvanized pipes, their connection methods, and relevant installation codes, emphasizing that,…
Many companies, when designing their production lines, often consider locating air-compressor receiver tanks directly within the workshop to save space. However, as pressure vessels, receiver tanks must be installed in strict compliance with safety regulations. This article examines…
Compressed air storage tanks fully meet the definition of sealed pressurized vessels, as they are airtight and contain gas at a pressure higher than atmospheric pressure. When specific pressure and volume criteria are met, such tanks are classified…

At what working pressure of an air-compressor station must explosion‑resistance measures be considered, and where is this requirement specified?
The explosion‑resistance and explosion‑protection design of air compressor stations is directly critical to production safety. This paper examines the relationship between operating pressures in air compressor stations and relevant explosion‑resistance standards, and provides a detailed analysis of the…
In compressed air systems, the air receiver tank is the most typical and legally designated pressure vessel component. Moreover, in certain screw compressors, the oil–gas separator tank also falls under the category of pressure vessels when it meets…
Compressed air systems in pharmaceutical manufacturing play a critical role. This article examines whether such systems qualify as pressure vessels, analyzes the relevant regulations and standards, delineates the criteria for classifying pressure vessels, and outlines the compliance requirements…
This article examines whether small mobile air compressors qualify as pressure vessels and special equipment. It provides a detailed analysis of the criteria for defining pressure vessels, including key parameters such as operating pressure, vessel volume, and the…
