In order to increase the popularity of the container section, an \"One Question per Day\" activity was launched under the guidance of the leaders, aiming to foster active technical exchanges while also providing financial rewards to users. There is a reaction vessel that meets the monitoring requirements; the maximum operating pressure of its inner cylinder is 0.052 MPa (400 mmHg), the maximum operating temperature is 120°C, and the medium involved is flammable, explosive, and of moderate hazard. Jacket: Maximum operating pressure of 0.6 MPa (gauge pressure), maximum operating temperature of 165°C; medium: saturated water vapor. Determine the container category: . A) Class I B) Class II C) Class III D) Other. Reply with the answer you think is correct; participating in the quiz earns +1 wealth point (points are added automatically per the rules). If your answer is incorrect, no additional points or feedback will be given. Getting all answers right earns an extra +3 wealth points. If you provide a detailed explanation or analysis of the questions and answers, you will receive additional wealth points as well. If your answer is correct and your explanation is accurate, it will be marked as the best reply (best assistance). Feel free to answer; please do not reply repeatedly ； If a, b, c, and d are all correct, choose e; answering a, b, c, d, e will result in no points. Note: We will close this post after 24 hours to reveal the answers and explanations, as well as the best response (the best help). Charisma Reward: If you post a topic in this section within two days to provide a detailed explanation of the knowledge points covered in this question, please reply to this post to inform us, and we will have a moderator award you charisma points. It is not allowed to simply copy and paste; original content is preferred, with at least some organization by the user along with personal insights. After registration, we will rank based on the content of the posts: the last-place contestant will receive +1 charm, the second-to-last place +2 charm, and so on, with the highest score getting +5 charm. http://bbs.hcbbs.com/thread-1381938-1-1.html Getting wealth by inviting friends: http://bbs.hcbbs.com/thread-1389197-1-1.html Seeking sponsors: Answer: A
Class I is classified according to the jacket. . . . . . . . . . . . . . .
The design pressure of the inner cylinder is greater than or equal to 0.1 MPa; B) Class II； The design pressure of the inner cylinder is less than 0.1 MPa, and it is classified as Class I according to the jacket classification
Answer: The maximum operating pressure of the inner cylinder in this question is 0.052 MPa; it does not fall under the category of pressure vessels, so no classification is required； The maximum operating pressure of the jacket is 0.6 MPa, the maximum operating temperature is 165°C, the medium is saturated water vapor, and it is classified as Category I. All containers of this station are ultimately classified as: A) Category I
There is a reaction vessel that meets the monitoring requirements; the maximum operating pressure of its inner cylinder is 0.052 MPa (400 mmHg), the maximum operating temperature is 120°C, and the medium involved is flammable, explosive, and of moderate hazard. Jacket: Maximum operating pressure of 0.6 MPa (gauge pressure), maximum operating temperature of 165°C; medium: saturated water vapor. Determine the container category: A. A) Class I B) Class II C) Class III D) Outside class

A) Class I B) Class II C) Class III D) Outside class
There is a reaction vessel that meets the monitoring requirements; the maximum operating pressure of its inner cylinder is 0.052 MPa (400 mmHg), the maximum operating temperature is 120°C, and the medium involved is flammable, explosive, and of moderate hazard. Jacket: Maximum operating pressure of 0.6 MPa (gauge pressure), maximum operating temperature of 165°C; medium: saturated water vapor. Determine the container category: C A) Class I B) Class II C) Class III D) Other
There is a reaction vessel that meets the monitoring requirements; the maximum operating pressure of its inner cylinder is 0.052 MPa (400 mmHg), the maximum operating temperature is 120°C, and the medium involved is flammable, explosive, and of moderate hazard. Jacket: Maximum operating pressure of 0.6 MPa (gauge pressure), maximum operating temperature of 165°C; medium: saturated water vapor. Determine the container category: . A) Class I
The correct answer to this question should be A; the inner cylinder does not actually fall into any category, and its classification is determined solely based on the jacket.
There is a reaction vessel that meets the monitoring requirements; the maximum operating pressure of its inner cylinder is 0.052 MPa (400 mmHg), the maximum operating temperature is 120°C, and the medium involved is flammable, explosive, and of moderate hazard. Jacket: Maximum operating pressure of 0.6 MPa (gauge pressure), maximum operating temperature of 165°C; medium: saturated water vapor. Determine the container category: B) Class II. Analysis: The maximum operating pressure is 0.6 MPa (gauge pressure), which classifies it as a low-pressure reaction vessel; the medium inside the inner cylinder is flammable, explosive, and of moderate hazard. This reaction vessel falls under item 3 of Category 2 pressure vessels, namely low-pressure reaction vessels and low-pressure storage vessels (only for flammable media or media with moderate toxicity).
