Glycol corrosion
Glycol corrosion
(OP)
I've been asked to verify if a carbon steel pipe filled with a mixture of ethylen glycol and distilled water (ratio 1,5/1)at ambient temperature and with no flow can corrode: filling was done in may this year and expected un-filling shall be in next December. In my opinion answer is no since glycol decomposes only at relatively high temperatures but on the other hand the use of glycol+water mixture without any corrosion inhibitor is not usual

Sounds like equipment put into wet lay-up. An inhibitor would have been cheap insurance.

Corrosion, every where, all the time.
Manage it or it will manage you.

Anyone else have any thoughts? I don't think leaving it as is will cause any great problems.
If you do inject some inhibitor now you can minimize your cleaning work later.
