Detailed Classification Of Pressure Vessels

Detailed classification of Pressure Vessels according to their use

Pressure vessels are sealed vessels that are subjected to gas or liquid pressure internally or externally and have high requirements for safety. Pressure vessels are mainly cylindrical, a few are spherical or other shapes. Cylindrical pressure vessels are usually composed of cylinder, head, receiver, flange and other parts and components, the higher the working pressure of the pressure vessel, the thicker the wall of the cylinder should be.

According to the role of the process can be subdivided into four main categories.

1, storage pressure vessels (C, of which the spherical tank for B): mainly for storage, holding gas, liquid, liquefied gas and other media pressure vessels, such as various types of Storage Tanks.

Storage Tank


2, reaction pressure vessel (R): mainly used to complete the physical and chemical reaction of the medium pressure vessel. Such as reactor, reactor kettle, decomposition pot, vulcanization tank, decomposition tower, polymerization tower, autoclave, ultra-high pressure kettle, synthesis tower, transformation furnace, cooking pot, steam ball, autoclave, gas generator, etc.

3, heat exchange pressure vessel (E): mainly for the completion of the medium of heat exchange pressure vessel. Such as shell and tube waste heat boiler, heat exchanger, cooler, condenser, evaporator, heater, disinfection pot, dyer, drying cylinder, steam frying pan, preheating pot, solvent preheater, steam pot, steam off machine, electric steam generator, gas generator water jacket, etc.

Heat Exchanger


4, separation pressure vessel (S): mainly used to complete the medium of fluid pressure balance buffer and gas purification and separation of pressure vessels. Such as separator, filter, oil collector, buffer, scrubber, absorption tower, copper washing tower, drying tower, steam tower, sub-vapor cylinder, deaerator, etc.
