Categorizing Vessels by Pressure, Design Temperature, and Installation

Categorizing Vessels by Pressure, Design Temperature, and Installation

Pressure vessels can be classified based on various factors, including pressure-bearing methods, design temperature, and installation method. 1. Pressure-Bearing Methods: Pressure vessels are categorized into two major types based on pressure-bearing methods: (1) Internal Pressure Vessels: These containers have media pressure inside the shell. The design focuses on wall thickness determined by strength calculations. (1) External Pressure Vessels: These containers have media pressure outside the...

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 Specify the Medium in the Process Parameters of a Pressure Vessel?

How to Specify the Medium in the Process Parameters of a Pressure Vessel?

The term "medium" in the context refers to the substance contained in the pressure vessel, existing in a liquid, gaseous, or gas-liquid mixed state. The safety of pressure vessels is intricately linked to the nature of the contained media. Different characteristics of the media necessitate varied requirements for the material, manufacturing, and utilization of the container. Pressure vessels may contain flammable, explosive, corrosive, or toxic substances, requiring careful attention during...

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...

Defining Pressure in the Process Parameters of a Pressure Vessel

Defining Pressure in the Process Parameters of a Pressure Vessel

In the specifications or standards for various pressure vessels, terms such as working pressure, maximum pressure, and design pressure are frequently encountered. Here are their definitions: (1) Operating Pressure: Operating pressure, also known as working pressure, denotes the pressure at the top of the container during regular process operations, excluding hydrostatic pressure. (2) Maximum Working Pressure: This refers to the highest pressure that the top of the vessel may experience during process...
