First, check whether your container is a cryogenic container; if it is, then it’s not suitable. Your information is incomplete regarding whether it belongs to a low-temperature container.
Page 9 of GB150 specifies requirements for using Q235-C steel plates in shells.
When Q235-C is used in pressure vessels within category 150, the operating temperature ranges from 0 to 400℃
According to GB150-1998, it is not allowed! Q235C steel plates can only be used to manufacture containers for temperatures ranging from 0 to 400 degrees Celsius
Page 9 of GB150 specifies specific requirements for using Q235-C steel plates in shells; it is not acceptable! Since Q235C steel plates can only be used to manufacture containers for temperatures ranging from 0 to 400 degrees Celsius, and the actual operating temperature of the equipment is -30 degrees Celsius, Q235C steel plates cannot be used to make containers in this case.
If external insulation is applied to the equipment, it can be used at temperatures above zero degrees.
I can’t understand what was said upstairs; I’m not sure if that is called covering one’s ears while stealing a bell
Please note that the original poster is referring to ambient temperature!
It’s possible, but there are specific conditions for its application
The ambient temperature is -30 degrees, so the design temperature must be equal to or less than the ambient temperature! Therefore, Q235-C cannot be used
