Stainless Steel pipe in sprinkler systems

[Morey, Mike]

I'm sure this has been addressed but I'm not finding it after some searching, are there stainless pipes that fall into the general approvals of NFPA 13 (I don't have full access to ASTM/ANSI but the stuff called out in NFPA 13 doesn't seem to be for stainless pipe), or is there specifically approved stainless pipe/fittings for sprinkler work? Or will we need to get a variance based on it being "better"? We're working in a clean environment and are probably going to provide socket weld fittings or threaded fittings and back weld them (other than the heads obviously). Socket weld fittings are mentioned, but the only mention of stainless anywhere in the standard is the C factor table.

The problem may be joining pipe and outlets. What about copper?

Typically the cleaning solvents used are not brass/copper friendly. I'm guessing since the request was for stainless pipe the sprinklers will be exposed so they'll be some form of corrosion resistant heads (wax/lead?), I would assume the heads would be soft enough to seal well but I'll have to pass that question on.

Why not grooved? Victaulic has SS couplings and mechanical tees.
Just a thought...

Did they say which stainless would be compatible? 304, 316, ...
