Per NFPA 13 2016 edition, 8.16.4.1.5 – Water filled piping shall be allowed to be installed in areas where the temperature is less than 40 degrees when heat loss calculations performed by a professional engineer verify that the system will not freeze. Is that what you were looking for? It can

I also had some luck convincing facilities installing non-code required generators to include valve room heat in circuits powered. Air compressor. FACU as well of course. Tiny draw. Best. > On Apr 14, 2020, at 13:13, Reed A. Roisum, SET via Sprinklerforum > wrote: > > Check out FMDS 8-29

I’m assuming the reason for insulting the pipe in the valve room is to prevent it from sweating due to the difference in temps between the exposure of the refrigerator versus the temperature of the riser room? Technically insulating to prevent condensation isn’t a requirement, however it might

Is the riser pipe cold where it comes through the wall? Is pipe sweating a problem, causing corrosion? On Tue, Apr 14, 2020 at 3:13 PM Reed A. Roisum, SET via Sprinklerforum < sprinklerforum@lists.firesprinkler.org> wrote: > Check out FMDS 8-29 Refrigerated Storage…particularly the section on >

I was always more concerned that the valve room was insulated, to slow cooling during power outage. Are you attempting to keep the pipe interior cold? This would seem to be result of insulating it in the heated room, at least downstream of valves. Best. Bruce Verhei > On Apr 14, 2020, at

I have seen it done but cannot seem to find the code reference in the Factory Mutual Data Sheets. We have a refrigerated storage building protected with a double interlock pre-action system. The valves are located in a heated mechanical room next to the freezers, with the risers penetrating
