What material should be used for pipes containing glacial acetic acid? We have been using 316L in the past, but this time our purchasing department made a mistake and ordered the national standard 321 instead (they were not familiar with the grade designation for 321). Can 321 be used as a substitute for 316L?

321 has poor resistance to acetic acid corrosion, and is inferior to 316L. I recommend an article for you to read; I hope it will be helpful. http://www.docin.com/p-1094447983.html

It is recommended to use 316L; if the temperature is high, it still won’t work.

It should work; it’s fine as long as there are no chloride ions

Can pipes lined with PTFE be used? The cost is low
