I have been unable to find any data or chemical compatibility for using 316 stainless steel pipe with cyanuric acid. I found a chart that suggests 316 stainless steel is OK to use with cyanic acid though. Do you know if 316 stainless steel is OK to use to transport cyanuric acid? Operating pressure would be 125 psig and max temperature would be 100 degrees F with water added to slurry.
Have an insight or suggestion?

Re: Is 316 stainless steel pipe compatible with cyanuric acid?15 May 2012 at 1:29pmI did a quick check and I couldn’t find any compatibility data for cyanuric acid either. The concept of using compatibility data from a surrogate like cyanic acid when one cannot find data for a chemical of interest is sometimes acceptable. The "degree of acceptability" depends on how similar the chemicals are and what degree of risk one can tolerate. In this case, I would probably advise that some laboratory test be designed and run to generate specific data for the combination of cyanuric acid and 316 stainless steel.
