Corrosion and ash formation

Too small or missing holes are causing ash formation inside the pipe construction.
I heard ash is an acidic product which promotes corrosion, is it true?
Thanks and regards

A. Hi Meysam. I took a guess that this has something to do with hot dip galvanizing, but I really don't know. I think your question needs to be much longer so we can understand it. Thanks.
