Pressure Vessel Classification Method
Jun 22, 2017

The type of pressure vessel, press the pressure vessel in the production process of the principle of the role can be divided into:

Reaction pressure vessel (code R):

Mainly used to complete the physical and chemical reaction of the pressure vessel. Such as: reactor, reactor, decomposition pot, curing tank, decomposition tower, polymerization reactor, autoclave, autoclave, synthesis tower, conversion furnace, cooking pot, steam ball, autoclave, gas furnace.

Heat exchange pressure vessel (code E):

Mainly used to complete the heat exchange of media pressure vessel. Such as: shell and tube waste heat boiler, heat exchanger, cooler, condenser, evaporator, heater, disinfection pot, dyeing machine, dryer, steaming wok, preheating pot, solvent preheater, steamer, steam Off-line, electric steam generator, Pressure Vessel and Pressure Pipe Component gas furnace water jacket.

Separate pressure vessel (code S):

Mainly used to complete the fluid pressure balance buffer and gas purification separation of the pressure vessel. Such as: separator, filter, buffer, scrubber, absorption tower, copper washing tower, drying tower, stripping tower, oil collector, sub-cylinder, deaerator. Fourth, the storage pressure vessel (code C, which ball tank code B): mainly used for storage, containing gas, liquid, liquefied gas and other media pressure vessel. Such as: various types of storage tanks.

Storage pressure vessel (code C, where the ball tank code B):

Mainly used for storage, containing gas, liquid, Pressure Vessel and Pressure Pipe Component liquefied gas and other media pressure vessel.

Pressure vessel classification method:

(1) Basic division: The division of the pressure vessel category should be based on the characteristics of the media, according to the following requirements to select the classification diagram, and then according to the design pressure p (unit MPa) and volume V (unit L), marked coordinate points to determine the pressure vessel category The

(2) Multi-chamber pressure vessel classification: Multi-chamber pressure vessels (such as heat pipe management and shell, jacket containers, etc.) according to the category of high pressure chamber as the category of the container and in accordance with the type of use management. But should be in accordance with the respective categories of each pressure chamber were proposed design, Pressure Vessel and Pressure Pipe Component manufacturing technical requirements. When the pressure chamber is classified, the design pressure is taken from the design pressure and the volume of the pressure chamber.

(3) with the cavity of a variety of media pressure vessel classification: a pressure chamber with a variety of media, according to the group of high media classification categories.

(4) the pressure of the media content of a very small group of categories: When a hazardous substance in the medium content is very small, it should be based on its degree of harm and its comprehensive consideration, Pressure Vessel and Pressure Pipe Component according to the pressure vessel design unit to determine the media group classification category.

(5) the classification of special circumstances.

Classification of pressure vessel varieties

The pressure vessel is divided into reaction pressure vessel, heat exchange pressure vessel, separation pressure vessel and storage pressure vessel according to the principle of action in the production process. The specific division is as follows:

(1) reaction pressure vessel (code R), mainly used to complete the physical and chemical reaction of the pressure vessel, such as a variety of reactors, reactor, polymerization reactor, synthesis tower, conversion furnace, gas furnace,

(2) heat exchange pressure vessel (code E), Pressure Vessel and Pressure Pipe Component mainly used to complete the heat exchange of media pressure vessels, such as a variety of heat exchangers, coolers, condensers, evaporators and so on;

(3) Separate pressure vessel (code S), mainly for the completion of the fluid pressure balance buffer and gas purification separation of the pressure vessel, such as a variety of separators, filters, oil collectors, absorption tower, Drying tower, stripping tower, sub-cylinder, deaerator, etc .;

(4) storage pressure vessel (code C, which ball tank code B), mainly for storage, containing gas, liquid, liquefied gas and other media pressure vessels, such as various forms of storage tanks, buffer tank, disinfection pot, Printing machine, dryer, steamer and so on. In a pressure vessel, Pressure Vessel and Pressure Pipe Component if two or more processes are applied at the same time, the breed should be divided according to the main effect of the process.
