Urgent help regarding carbon dioxide storage tank problem
Thread Content
Urgent request for help. The customer has a liquid carbon dioxide storage tank. The inner tank material is 16MnDR. Due to the customer's operating error, the carbon dioxide in the tank formed into dry ice. After the carbon dioxide formed into dry ice, the temperature was lower than -40°C. However, the original design temperature of the tank liner was only -40°C. According to the standard, 16MnDR can only be used in situations higher than -40°C. Is there any way to test to determine whether the tank can still be used? urgent! ! !
I have never encountered this kind of situation. Have you considered conducting a new withstand voltage test? Air tightness test?
Personally, I think the first step is to raise the temperature and remove the dry ice, and then conduct some tests, such as pressure resistance, vacuum degree, etc. . . All are qualified and should be able to be used normally. . .
There is no way to detect the hazards of low temperature. Check the impact test temperature during manufacturing. Generally, the impact test must be below the minimum design metal temperature to pass the impact test. If the impact test is below -40 and passes, it means there is no problem. Otherwise, it will be troublesome. There is no way to test for low temperature brittle fracture.
