Agreed. Where I am located geographically, the low temps are temporary. Not of a duration that a good insulation can't handle. I'm in a position to answer a GC's question. But back to my question; can I or can't I use insulation on branch lines (per NFPA13)? I'm against it. In my location the problem I see with just insulation without heat tape is the water in the part of the sprinkler just beneath the seat (I'm dealing with upright sprinklers here). I would be very afraid of this. Plus the thickness of the insulation may go to the diameter that may require sprigs.
Thanks to you and to Timothy for your input. Russell <Insulation on a pipe with non-flowing water is pointless (except for temporary exposures to low temperatures). Insulation can only slow the transmission of heat from the pipe, it does nothing to produce heat.> _______________________________________________ Sprinklerforum mailing list http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
