GDCM Discussion Forums > Copper Piping in a Data Center

From a question sent to me early last month:
"Is it acceptable to have copper piping that is greater than 2" in our data center? Our specifications state copper up to 2", but not greater than that. Is it ok to go higher, and if so, how much?"

As Computer Room Air Conditioning (CRAC) units have increased in capacity, the piping to them has increased as well. There may be a fear about using copper piping that is greater than 2", since brazing at 2.5 to 3" becomes more tricky to do correctly. In my experience, a contractor has been permitted to do 3" copper piping, and even 4" in one instance, but the quality testing and inspection was increased to make sure that it was done correctly.

Your experience with a contractor and their confidence that they can complete this work, and own the consequences of needing to do work over again as needed, is vital to this decision. The last thing that you want is for a contractor to train people to do larger copper piping on your project. Doing an interview with the actual installers can help a lot on your decision, especially if they can describe how they are going to install it and point to other projects that went smoothly.
