For example, a container, the medium is filled with water, and the working pressure is 0 if the working temperature is 80 °C. 6Mpa, it is not a pressure vessel, because it has no gas in it and is less than 100 °. it is not a pressure vessel. if the water is not filled and there is gas phase space on it, it is a pressure vessel, if it is full of water and the working temperature is higher than 100 °C, it is also a pressure vessel, so you can't get an answer if you ask a device name is a pressure vessel. you ask, it can only be said
