Why do underground water pipes not freeze?
If water in the pipes does not freeze at -40 degrees Celcius, there is a reason for that. Either the pipes are indoors in heated spaces, or they are heat traced, or they are drained, or they are insulated, or they are buried, or water in the pipes is running (or at least dripping), at least intermittently.
Why do underground water pipes burst?

Can you spray foam over water pipes?
Spray foam helps protect water pipes from cold temperatures. It is also water resistant which makes it ideal for use near water pipes. Insulate and air seal basement rim joists with spray foam insulation. This helps keep cold outside air from infiltrating the basement and away from pipes.
Why do North pipes not burst?
Generally, houses in northern climates are built with pipes located on the inside of the building insulation. This usually protects them from subfreezing weather, although extreme cold, insufficient insulation and holes that allow cold air to come into contact with pipes can still lead to freezing and bursting.
What causes water pipes to crack?

Why do pipes burst in cold weather?
When the temperatures drop down to around 0 degrees Fahrenheit, the water which runs through your pipes is actually capable of freezing in place. As more water freezes and accumulates in one area of a pipe, more and more pressure is applied to that area. When the pressure becomes too much, the pipe will burst.
Why are water pipes so old?
