Is the design temperature for non-insulated pipes at a minimum of “120°C”?

One of the uniform regulations for the process engineering aspects of a certain project states: “For pipes without insulation: the design temperature of the pipes should not be lower than 95% of the maximum temperature of the medium, with a minimum of 120°C.” What does this “120°C” refer to? What is the underlying meaning? Why is this requirement?
I guess it’s because lower temperatures in winter make it easier for the medium to freeze. :lol
What is the relationship between the design temperature and the likelihood of freezing? I don’t know what medium you are on or in what region you are. But the statement that “the design temperature should be no lower than 95% of the maximum operating temperature” is clearly problematic; the design temperature must certainly be higher than the maximum operating temperature, plus a safety margin.
I agree with what was said above: how can the design temperature be lower than the maximum temperature? If it’s set at 95%, wouldn’t that pose a risk at the maximum temperature?
