Categories of Pressure Vessels Based on Pressure Levels

Categories of Pressure Vessels Based on Pressure Levels

Pressure vessels are categorized based on pressure levels, which include low pressure, medium pressure, high pressure, and ultra-high pressure: Low Pressure Pressure Vessels(Code L): Pressure ranging from 0.1MPa to less than 1.6MPa. Medium Pressure Pressure Vessels(Code M): Pressure from 1.6MPa to less than 10MPa. High Pressure Pressure Vessels(Code H): Pressure from 10MPa to less than 100MPa. Ultra-High Pressure Pressure Vessels(Code U): Pressure equal to or exceeding 100MPa.

How to Determine Temperature in Pressure Vessel Process Parameters?

How to Determine Temperature in Pressure Vessel Process Parameters?

1. Operational Temperature: It is the temperature of the working medium as measured by a temperature instrument during the pressure vessel's operation. 2. Design Temperature: Unlike the temperature the internal medium may reach, the design temperature of a pressure vessel refers to the metal temperature of the pressure component under the designated design pressure during normal operation. This value should not be lower than the maximum metal temperature the component may reach. For pressure...
