Pressure vessel

In compressed air systems, the pressure vessel characteristics of air receivers, refrigerant dryers, and filters differ. Air receivers qualify as statutory pressure vessels because they meet the applicable pressure–volume criteria; the refrigerant dryer as a whole is not…

Whether an air compressor is subject to special equipment regulations is not determined by its motor power, but rather by the working pressure and volume of the accompanying air receiver tank. This article provides a detailed analysis of…

As a critical pressure vessel, the air receiver tank’s design life directly affects both its safe operation and economic efficiency. This paper provides a detailed analysis—covering fundamental concepts, key influencing factors, regulatory and code requirements, and practical assessment…

Once the design service life of a pressure vessel for an air compressor has expired, it must not be put back into service. The design service life serves as a safety‑based reference period rather than an absolute end‑of‑life…

The pressure setting of a compressed air storage tank directly affects the safety and efficiency of the system. This article provides a detailed analysis of the typical operating pressure range, design pressure standards, and key considerations for pressure…

The design life of a pressure vessel is not fixed; it is determined by the design organization based on a comprehensive assessment of the medium’s properties, operating conditions, and material performance. Commonly specified design lives are 10, 15,…

This study investigates whether the design life of a 20 m³ horizontal compressed air buffer tank can be extended to 25 or 50 years. It analyzes the key factors that influence the tank’s service life, including material selection,…

The air compressor host itself is not classified as special equipment; however, the accompanying air receivers and pressure piping that meet specified parameters are considered special equipment. Enterprises are required by law to register their use, conduct periodic…
