Modified multiple-choice question...Everything is going well. ..............................................................The question is taken from the standard NB/T 47041-2014 «Tower Containers». Please point out any inaccuracies in the modifications; if you have any good suggestions, feel free to reply with them – rewards will be given generously. ........................................................................... Answers (multiple choice, multiple choice, multiple choice) please fill in in order. Reward rules: 1 wealth for participation, 3 wealth for each correct answer, up to a maximum of 10 wealth. ...........................................................................1. The maximum allowable operating pressure of a tower-type vessel is calculated based on the effective thickness of each pressure-bearing component of the vessel, taking into account all the loads applied to that component, and the minimum value is adopted. A. Correct ； B. Incorrect ； ---------------------2. Test temperature refers to the temperature of the test medium during voltage resistance tests or leakage tests. A. Correct ； B. Incorrect ； ---------------------3. The design temperature refers to the metal temperature of the component specified under normal operating conditions (the average temperature along the metal cross-section of the component). A. Correct ； B. Incorrect ； ---------------------Answers: 1. A, 2. B. (The metal temperature of the shell of a tower-type vessel during pressure resistance tests or leakage tests at the test temperature.) ) (This question is prone to errors, as the standard specifies temperatures for liquids in regard to the test temperatures; measuring the temperature of liquids is easier, and by controlling the temperature of the liquid, the temperature of the metal can be controlled. Therefore, the standard requires that pressure be increased only when the temperature of the metal on the vessel walls is close to that of the liquid.) ) 3. A (Do not interpret this as the temperature of the medium; analyze each case on its own)
