Extreme temperatures or temperature changes that are too cold or too hot will cause many failures, such as:
1 Under low temperature, the collision of tools, vehicles or rocks will cause damages such as pipe rupture;
2 The heat of chemical dissolution and other heat sources will cause pipeline deformation and damage;
3 When the pipe is fixed on concrete or other objects, the pipe may break when there is a sudden temperature change;
4 The pipeline is filled with liquid. If the liquid freezes, the pipeline may break;
5 When the liquid is pumped in with a pump and the liquid is circulated again, the pipeline and fittings may malfunction;
6 The effect of thermal expansion and contraction will cause pipeline failure.
