Why does the water pipe of automobile thermostat need to have high temperature resistance?

The main reason why the water pipe connected to the thermostat of an automobile needs high temperature resistance is that the engine will generate high temperature during operation, and the coolant in the cooling system needs to circulate through the water pipe to take away the heat generated by the engine, so as to maintain the engine in a suitable working temperature range. Therefore, the water pipe needs to be able to withstand the working conditions in high temperature environment, so as to ensure that it will not be deformed, softened or broken due to high temperature when the engine is running.

If the water pipe does not have high temperature resistance, it may lose its original strength and stability in high temperature environment, resulting in deformation, softening or rupture of the water pipe, failure of the cooling system and serious consequences of overheating or even damage of the engine. Therefore, in order to ensure the normal operation of the cooling system and the safety performance of the engine, the water pipe of the automobile thermostat needs to be made of high-temperature resistant materials, which can maintain stable performance in high-temperature environment, ensure that the coolant can effectively circulate and cool the engine, and keep the engine in a suitable working temperature range.
