In a prior life, the folks at Hilti have provided me ‘Engineered Judgements’ for installations that don’t fully comply with the UL listing.

I would think this would have come up before now. Quote: "We do not perform any fire penetration tests on our sprinkler pipe. Engineered Pipe (FLOW) has been manufactured for over 25 years. I would think 3M or others would have a fire rated penetration tested thru UL. They have these details for electrical conduit/PVC Pipe which is a thinner wall thickness than a Flow sprinkler pipe. Please check with your fire stop manufacturer for their recommendations." All the details I have looked at are, as bullmoose said, they are OK with EMT, PVC, Copper etc. But steel pipe has to be "Sch.10 (or heavier)" On Thu, Aug 10, 2017 at 7:39 AM, Roland Huggins <rhugg...@firesprinkler.org<mailto:rhugg...@firesprinkler.org>> wrote: Did you contact Eddy Flow since they have a vested interest?

I'm penetrating some walls with listed thinwall pipe (Eddy Flow). All of the firestop details from Hilti or 3M say the penetrant shall be "Sch.10 or heavier". Is their a detail for listed thinwall? Do I have to upsize to Sch.10 at the wall to penetrate it?
