Why are pipes with smaller diameters more prone to freezing in winter?

Why are pipes with smaller diameters more prone to freezing in winter? Our leader said that in winter, we only need to insulate and protect against freezing the pipelines outside with a diameter of less than DN50
Do you think the Yangtze River freezes easily, or does the stream near your home freeze easily? ;P
It’s cold everywhere; small pipe diameters make it easy for the core to get cold
It contains less heat; it’s like giving you a cup versus a drop – the drop cools down faster
For pipes with a diameter of less than 50, the external contact area constitutes a larger proportion of the total pipe surface, which results in faster heat conduction and cooling; as a result, such pipes are more prone to freezing. Please refer to the Nanquan insulation system for more details；
I don’t even know what to say to such a question
In the northeast, where temperatures are below minus 20 degrees, even DN100 pipes will freeze without insulation
With a small diameter, less volume flows through in a given time; at the same ambient temperature, less heat transfer is required to drop it to the freezing point, making it easier for it to freeze.
