In which of the following situations is it necessary to use a burst disc device as a pressure relief mechanism for pressure vessels? A. The medium inside the container is an extremely or highly hazardous medium ； B. The pressure inside the container increases rapidly ； C. The container has high requirements for sealing ； D. Pressure vessels with a design pressure higher than 10 MPa. ---------------------2. It is specified that the minimum width of the shell plate shall be not less than ( ) mm. A.500 B.600 C. 700 D. 800---------------------3. For pressure-bearing components subjected to pressures from two chambers simultaneously, the design pressure in the design parameters should take into account the maximum pressure difference that may occur between the two chambers. ( ) A. Correct B. Incorrect --------------------- Answers: 1. B C 2. A 3. B 1. Comment: This question tests the overpressure relief devices specified in Appendix B of GB150.1, refer to B.3.7. 2. Comments: The structural requirements for steel spherical storage tanks as specified in GB GB12337-2014 are given in 5.2.2. 3. Comments: Section 4.3.3 of GB150.1 specifies how to consider the design pressure and calculated pressure for multi-chamber vessels. This question is clearly designed to test that the calculated pressure of a common element depends on the maximum pressure difference between the two chambers.
