Pressure vessel is interior or exterior bear gas or liquid pressure, right security has higher demand, common be used in a general sense is used at finishing reaction in industrial production, pass qualitative, conduct heat, depart and store the sealed container that waits for manufacturing process.

Pressure vessel basically is cylindrical, minority is globose or other form. Cylindrical pressure vessel normally by cylindrical shell, head, take-over, the spare parts such as flange and component composition, pressure vessel actuating pressure is higher, the wall of cylindrical shell should be jumped over thick.

The classified means of pressure vessel needs according to what differ, have a lot of kinds. Commonner. By the design of pressure vessel pressure cent is: Low pressure, middling pressure, high pressure, superhigh pressure; By production process cent is: Reaction, heat exchange, store, detached container.

Pressure vessel classification

Press pressure grade classification: Pressure vessel can be divided for internal pressure container and outside press container.

Internal pressure container can press design pressure again (P) size cent is 4 pressure grade, specific differentiate as follows:

Low pressure (＜ of P of ≤ of 0.1 MPa of container of code name L) 1.6 MPa;

Middling pressure (10.0 MPa; of ＜ of P of ≤ of 1.6 MPa of container of code name M)

High pressure (＜ of ≤ P of 10 MPa of container of code name H) 100 MPa;

Extrahigh voltage (100MPa of ≥ of P of container of code name U) .

Press the action classification of container aborning: Reaction pressure vessel (code name R) : Does Mei Yu vase Shan Lu solid Nai holds in custody Х of rancorring ⒒  from Α ?

Heat exchange pressure vessel (code name E) : Does Mei Yu vase is hill scull fact graceful reject beat changes arc?

Detached pressure vessel (code name S) : Does Mei Yu vase Qian of shake of Piao of glue of ζ of buy of Ti of Xiao of hill scull solid herd pushs  extensive region to change  to cast Ge?

Store pressure vessel (code name C, among them B of sphere code name) : Use at storing, the medium such as full-dress gas, liquid, liquefacient gas.

In a kind of pressure vessel, when be like the craft action principle that has two above at the same time, should differentiate by the main effect in process breed.

By installation means classifies: Stationary pressure vessel: Have fixed installation and use ground place, the pressure vessel with craft condition and operation fixedder also personnel.

Movable type pressure vessel: Internal pressure bears not only when using or outside ballast carries on his shoulder or back, carry the wallop that still can be caused as a result of in-house medium rock in the process, and what carriage process brings is exterior bump and oscillatory load, be in consequently structure, use and safe respect all has its special demand.
