Corrosion of carbon steel by ethylene glycol
Thread Content
Is 99.9% ethylene glycol highly corrosive to carbon steel?
Ethylene glycol with very high purity has little corrosive effect on metals such as copper, carbon steel, and stainless steel
A temperature of 99.9% ethylene glycol below 100°C results in very mild corrosion of carbon steel
Ethylene glycol has almost no corrosive effect on carbon, but it can easily decompose into glycolic acid or oxalic acid – which goes without saying! ! ! Therefore, ethylene glycol must be equipped with a matching corrosion inhibitor, that is, corrosion-inhibiting ethylene glycol!
99.9% ethylene glycol causes little to no corrosion to carbon steel; however, when it is mixed with water to reach a certain concentration, it can cause corrosion and also acidify the environment. Only proprietary enhancers can be added
Ethylene glycol itself does not corrode carbon steel, unless it is oxidized into an acid.
What is the difference between the proprietary performance enhancer you mentioned and the corrosion inhibitor mentioned above? Are they the same thing? ? ?
Under what conditions is ethylene glycol oxidized to an acid? ? ? ?
