Galvanized pipes and black pipes in dry pipe systems

Dear All,

Is there a requirement of NFPA13 to use galvanized pipes for dry pipe systems of CMDA sprinklers?

I have a design of preaction single interlock system with standard spray sprinklers k115 with 12,2mm density inside the building with temperature above 4 Celsius degrees. I haven't found in NFPA13 the requirement to use galvanized pipes for dry and preaction sprinkler systems with standard spray sprinklers.

Thank you for your help.
