Pressure vessel (yālì ró ng qì), English: pressure vessel refers to a closed device that contains gas or liquid and carries a certain pressure. In order to implement scientific management and safety inspection more effectively, pressure vessels are divided into three categories according to working pressure, medium harmfulness and its role in production in China's Pressure Vessel Safety Supervision Regulations. And for each category of pressure vessels in the design, manufacturing process, as well as inspection items, content and methods to make different provisions. Pressure vessels have implemented the safety and quality licensing system for imported goods, and goods that have not obtained the import safety and quality license are not allowed to be imported. According to the latest TSG21-2016 "Safety and Technical Supervision Regulations for Fixed Pressure Vessels", it should be divided into the first group of media and the second group of media according to the media, and then classified into categories I, II and III according to the pressure and volume. The so-called first, second and third categories of the old capacity regulations are no longer applicable.
A pressure vessel is a closed container that can withstand pressure. The use of pressure vessels is extremely wide, it has an important position and role in many sectors such as industry, civil, military and many other fields of scientific research. Among them, the pressure vessels used in the chemical industry and petrochemical industry are the most, and the pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels. Pressure vessels are mainly used for heat transfer, mass transfer, reaction and other technological processes in the chemical and petrochemical fields, as well as storage and transportation of pressurized gases or liquefied gases; they are also widely used in other industrial and civil fields, such as air compressors. All kinds of special compressors and auxiliary machines of refrigeration compressors (coolers, buffers, oil-water separators, gas storage tanks, evaporators, liquid coolant storage tanks, etc.) are pressure vessels.

Product introduction:
The high-pressure heater is a device that uses steam turbine extraction to heat boiler feed water. It can improve the thermal efficiency of the power plant, save fuel, and help the safe operation of the unit. The device is generally fully welded, U-tube tube-sheet structure. It consists of three sections: superheated section, saturated section and cooling section. When the superheated steam enters the shell from the steam inlet, it first passes through the superheated steam cooling section, during which the superheated steam is cooled into saturated steam, then enters the steam condensation section, the steam condenses into water, the condensed hot water enters the drain cooling section, continues to release heat to be absorbed by the feed water, and finally the condensate flows out through the drain outlet. The device has significant advantages such as low energy consumption, compact structure, small occupied area, long service life, etc., and can strictly control the drainage water level and drainage flow rate, and meet the requirements of customers for water supply and drainage end difference. There are three types of high-pressure heaters: inverted vertical, positive vertical and horizontal. Safety accessories such as safety valve, pressure gauge, thermometer and level gauge are provided on the equipment to ensure the safe and efficient operation of the equipment.
