Why do the pipes here in Xinjiang freeze and crack so easily?

Discussion on the corrosion of ordinary carbon steel by soft water with a pH of 6
I’m not sure about other media, but if there is water vapor, water of the same volume expands when it freezes, which can cause the pipes to burst.
It’s a temperature issue; winters in Xinjiang are cold, and ordinary carbon steel cannot withstand low temperatures, so it easily gets damaged. Moreover, the medium transported through the pipes is water, and freezing and cracking occur quite frequently when this happens
Without anti-freezing measures, any pipe is prone to freezing and cracking.
Hehe, Xinjiang. Xinjiang is the largest in terms of the range of latitudes it covers. Anti-freezing measures cannot be generalized for Xinjiang; wherever the local freezing point is reached, anti-freezing and insulation measures must be taken.
That’s right; Xinjiang is quite large in extent, and it should be divided into regions, with the determination based on ambient temperature and wet-bulb temperature. As for insulating the pipes, it’s basic common sense – leaving them exposed to the elements will definitely cause them to crack from freezing. Even in North China, without proper insulation in winter, blockages can occur even if the flow rate decreases.
Check the corrosion curve; it’s better if it has a slightly more alkaline tendency
If the pH level is too low, not only will there be problems with freezing cracks, but there will also be corrosion issues!
