It's a dirty word on this Forum to some, but I would consider looking into PEX tubing if you can get it to work hydraulically. The challenges with PEX are smaller ID and temp/pressure rating. However, PEX can easily be attached to the formwork for concrete or Gunnite and we have used it with great success in wine caves out here on the Left Side. Aggregate concrete has a fire resistance rating that can be extrapolated as about 22.2 minutes per inch and I've done tech reports for two wine cave applications where we obtained equivalency approval for this application.

I was able to find one article about it at the monolithic dome institute's website here: http://static.monolithic.com/construction/sprinklers/index.html Looks crazy, but also interesting.
