We were changing heat exchanger pipe material from c/s to s/s due to being advised that carbon steel will quickly contaminate the DI water. We now were asked to investigate making heat exchanger using copper pipe since the Induction power supply vendor rutinely runs DI water in copper manifold...
Thanks again for your guys responses. I'm definitely convinced that DI water and cs is not a good combination. Design going forward will be utilizing s/s pipe.
- But, I still am curious about the effect on the carbon pipe itself. I understand the water will get contaminated quickly from contact...
Thanks for quick response...
Our Customer will be chemically treating the closed loop DI water system, but I am not positive of the particulars(what chemicals, how often, etc). He has a 1,000gpm total capacity so the water passing thru the heat exchanger assy will get dumped back into the main...
We designed a fin-tube heat exchanger assy using carbon steel pipe and fins. Our Customer has now advised he plans on running DI water in this water circuit. The water will probably enter heat exchanger tubing bundle (12 tubes x 120"lg) at 45-60F and exit at 100-110F after absorbing transferred...
