What are the differences in pressure between atmospheric vessels and pressure vessels?
Containers are divided into two main categories based on the pressure they can withstand: atmospheric pressure containers and pressure vessels. Vessels with a maximum design pressure of P ≥ 0.1 MPa are referred to as pressure vessels, while those with a pressure of < 0.1 MPa are known as atmospheric vessels. The classification is specified in the Code for Pressure Vessels, as follows: (1) The design pressure P is divided into four categories: low pressure, medium pressure, high pressure, and ultra-high pressure ； Pressure class, Pressure class code, Design pressure range (MPa): Low pressure – L, 0.1≤P＜1.6MPa; Medium pressure – M, 1.6≤P＜10MPa; High pressure – H, 10≤P＜100MPa; Ultra-high pressure – U, P≥100MPa
