Is corrosion more likely to occur at low temperatures or at high temperatures in pipes?
Thread Content
I heard today that the corrosion of pipelines is basically caused by low-temperature corrosion. Corrosion is not easy to occur at high temperatures? Is that what it looks like? Why?
According to the literal meaning of the post, it should mean that corrosion is more likely to occur when liquid water exists at lower temperatures. For example, H2S dissolves in water and dissociates to produce H+, etc.
It cannot be generalized. The higher the temperature, the higher the energy of the outer electrons of metal atoms, and the easier it is to lose electrons and be corroded. ； If the pipeline medium is in the gas phase (such as water vapor), the lower the temperature, the easier it is to fall below the dew point and form a liquid, forming a corrosive liquid, which is more likely to corrode the pipeline metal.
Is it true that when other conditions are the same, high temperatures are more corrosive than low temperatures because molecules move faster?lol:lol
