Answer 2

it is due to plasticity, in colder countries temprature is very low near about or below 0°c.

so decrease in temprature result in decrease of elasticity. (♦elasticity is property by verture of it an object come to its original shape) so plasticity (♦opposite to elasticity) is increased and pipe are cracked or broke if these are bend more then their strength.
