Corrosion rate of 50% ethylene glycol aqueous solution
Thread Content
Temperature of 70–100 degrees Celsius, 50% water and 50% ethylene glycol; used in heating boilers. What is the corrosion rate? Specific figures along with their source would be appreciated!
There isn’t a specific numerical value, but at high temperatures of 100 degrees Celsius, the corrosion rate of ethylene glycol on equipment **increases**. If conditions permit, it is advisable to use a non-corrosive version of ethylene glycol, as that yields better results
