The Mechanical Section has introduced the \"Question of the Day\" feature, which not only helps to foster an active atmosphere for technical discussions and guide the direction of such exchanges but also provides users with financial rewards, enabling them to experience various cool features. According to the requirements of TSG R0004-2009, when carbon steel and low-alloy steel sheets are used to manufacture pressure vessel shells, they must be subjected to ultrasonic testing one by one. a. Used in a wet H2S corrosion environment, with a shell thickness of 8 mm ； b. The toxicity level of the medium contained is highly hazardous, and the shell thickness is 16 mm ； c. The design pressure is 10 MPa, and the shell thickness is 10 mm ； d. Those specified in the referenced standards of TSG R0004-2009 that require ultrasonic testing on a per-sheet basis ； The answer is bd. Refer to Section 2.5.1 of the Fixed Capacity Regulations. Please note: we will close this thread after 24 hours, and at that time we will announce the best response (the most helpful answer), along with the solution and explanation.

Standard TSG R0004-2009 stipulates that (D) carbon steel and low-alloy steel plates used for manufacturing pressure vessel shells shall be subjected to ultrasonic testing on a sheet-by-sheet basis. a. Used in a wet H2S corrosion environment, with a shell thickness of 8 mm ； b. The toxicity level of the medium contained is highly hazardous, and the shell thickness is 16 mm ； c. The design pressure is 10 MPa, and the shell thickness is 10 mm ； d. Those specified in the referenced standards of TSG R0004-2009 that require ultrasonic testing on a per-sheet basis ；
b. The toxicity level of the medium contained is highly hazardous, and the shell thickness is 16 mm； d. As stipulated in clause 2.5.1 of the fixed-volume gauge standards, which are required to undergo ultrasonic testing on a per-piece basis according to the referenced standards TSG R0004-2009
Standard TSG R0004-2009 stipulates that when carbon steel and low-alloy steel plates are used to manufacture pressure vessel shells, they must be subjected to ultrasonic testing one by one.
Answer: b. The toxicity level of the medium contained is highly hazardous, and the shell thickness is 16 mm；
It should be option C, as it is related to thickness
b. The toxicity level of the medium contained is highly hazardous, and the shell thickness is 16 mm； d. Those specified in the referenced standards of TSG R0004-2009 that require ultrasonic testing on a per-sheet basis ；
Answer: According to TSG R0004-2009, (b) and (d) specify that when carbon steel and low-alloy steel plates are used to manufacture pressure vessel shells, they must be subjected to ultrasonic testing one by one. a. Used in a wet H2S corrosion environment, with a shell thickness of 8 mm ； b. The toxicity level of the medium contained is highly hazardous, and the shell thickness is 16 mm ； c. The design pressure is 10 MPa, and the shell thickness is 10 mm ； d. Those specified in the referenced standards of TSG R0004-2009 that require ultrasonic testing on a per-sheet basis ；
