1. Strictly speaking, all (ASME-designed) items need to be marked, with the only difference being the numerical value, that is, what the MDMT value is. 2. It is necessary to distinguish whether the containers are designed according to national standards or ASME standards; ASME customers have specific requirements, and the concept of low temperature applied in China’s MDMT system differs from that in ASME’s system.
It is generally necessary to indicate this, especially for low-temperature equipment
For the design of general equipment, the maximum and minimum operating temperatures should be specified, right?
Pay attention to this minimum design metal temperature only when there are significant differences in material selection
