Pressure vessels have a wide range of applications and play an important role in many sectors such as industry, civilian use, military industry, as well as in many fields of scientific research. Pressure vessels are most commonly used in the chemical and petrochemical industries, with pressure vessels used only in the petrochemical industry accounting for about 50% of the total number of pressure vessels. Now let Zhongtian tell you two or three things about pressure vessels.
Classified by design pressure
① Low pressure (L) 0.1MPa ≤ P ＜ 1.6 MPa
② Medium pressure (M) 1.6 MPa ≤ P ＜ 10 MPa
③ High pressure (H) 10 MPa ≤ P ＜ 100 MPa
④ Ultra high pressure (U) P ≥ 100 MPa
Divided by the role in the manufacturing process
01
Reaction pressure vessel (R)
It is mainly used as a pressure vessel for completing physical and chemical reactions of media. Such as reactors, reaction vessels, decomposition pots, vulcanization tanks, decomposition towers, polymerization towers, high-pressure reactors, ultra-high pressure reactors, synthesis towers, conversion furnaces, cooking pots, steam balls, steam pressure reactors, gas generators, etc.
02
Heat exchange pressure vessel (E)
It is mainly used as a pressure vessel for heat exchange of media. Such as shell and tube waste heat boilers, heat exchangers, coolers, condensers, evaporators, heaters, disinfection pots, dyers, dryers, steaming and frying pans, preheating pots, solvent preheaters, steamers, steamers, electric steam generators, gas generator water jackets, etc.
03
Separate pressure vessel (S)
It is mainly used as a pressure vessel for fluid pressure balance buffering and gas purification separation of media. Such as separators, filters, oil collectors, buffers, scrubbers, absorption towers, copper washing towers, drying towers, stripping towers, steam separators, deaerators, etc.
04
Storage pressure vessel (C, with ball tank as B)
Mainly used as pressure vessels for storing and containing gases, liquids, liquefied gases and other media, such as various types of storage tanks.
Shandong Zhongtian Technology Engineering Co., Ltd. is a high-tech enterprise that integrates engineering design, technical consulting, project management, and project general contracting services. It has the qualification for pressure vessel design and can undertake pressure vessel design projects. With strong technical strength, numerous design achievements, and a wide range of business, its branches are located throughout the country and can provide design and services nearby.
Comprehensive classification
01
Fixed pressure vessel
The usage environment is fixed and cannot be moved. There are various types of working media, most of which are toxic, flammable, explosive, and corrosive chemicals. Such as spherical storage tanks, horizontal storage tanks, various heat exchangers, synthesis towers, reactors, dryers, separators, shell and tube waste heat boilers, manned containers (such as medical oxygen chambers), etc.
02
Mobile pressure vessel
It is mainly used in mobile applications as a packaging medium carried on transportation vehicles. Many working media are flammable, explosive, or toxic. Like the tanks of cars and railway tankers.
03
Gas cylinder pressure vessel
As a type of pressure vessel, society has a large number of high-pressure gas cylinders (such as hydrogen, oxygen, and nitrogen cylinders) and low-pressure gas cylinders (such as civilian liquefied petroleum gas cylinders). Many working media are also flammable, explosive, or toxic substances. It also has strong mobility, including long-distance movement during transportation and short distance movement during specific use. Such as liquefied petroleum gas cylinders, oxygen cylinders, hydrogen cylinders, nitrogen cylinders, carbon dioxide cylinders, liquid chlorine cylinders, liquid ammonia cylinders, and dissolved acetylene cylinders.
