Is it a pressure vessel?

This type of equipment does not exist alone. With the help of other pressure vessel declarations, please consult local supervision.* * mechanism. People are the authority.
The General Administration of Quality Supervision, Inspection and Quarantine is responsible for interpreting the "Special Equipment Catalog". Its scope is stipulated as gases with a maximum working pressure greater than or equal to 0.1MPa (gauge pressure), liquefied gases and liquids with a maximum operating temperature greater than or equal to the standard boiling point, fixed containers and mobile containers with a volume greater than or equal to 30L and an inner diameter (non-circular cross-section refers to the maximum geometric size of the inner boundary of the section) greater than or equal to 150mm. ； Cylinders containing gases, liquefied gases and liquids with a standard boiling point equal to or lower than 60°C whose nominal working pressure is greater than or equal to 0.2MPa (gauge pressure), and the product of pressure and volume is greater than or equal to 1.0MPa·L ； oxygen chamber. Please compare it with the text above to confirm based on the parameters in the picture you gave! ;P
It is a pressure vessel, but whether it is classified depends on the working pressure, but I can’t see clearly.
This is a pressure vessel, judged according to capacity regulations
This should not be counted. There is no stamped TS symbol in the upper right corner of the name brand. In addition, the product quality book and the manufacturing supervisory inspection certificate included in it are very clear.
Then I would like to ask whether the heater of a single-effect concentrator is considered a pressure vessel?
Sealed containers that store temperatures exceeding the standard boiling point are not pressure vessels.
This question from the poster tests the mastery and practical application of concepts. Once you understand the definition thoroughly, all such problems will be solved. Otherwise, some people say yes and some say no, and you can’t judge. If you want to convince others, you must first convince yourself. It is recommended to read more about 150 and large capacitance gauges, there are answers there.
Then it is not classified, but it is a pressure vessel
