The original question is actually very interesting. You mentioned Schedule 7 pipe and I bet pretty much everyone that read that immediately thought of listed flow pipe. Until there is a requirement to standardize the ID's there will not be an appetite to put "Schedule 7" in the standard in my opinion. Using it through the listed option is more preferable the thinner the wall gets. I do like the ability to use a non-listed product simply manufactured to the appropriate ASTM standard. Helps with some of the oddball sizes and galvanized. For many years, we have used "Schedule 7" and "Schedule 30 - listed threadable thinwall" as our standard compared to 10 & 40. Granted we do more plastic than steel but we have installed quite a bit of these listed steel pipe products. We have not experienced major issues with these products. We have never used the "Schedule 7" 6" pipe nor used "Schedule 5". The cost difference in a competitive environment cannot be ignored. My opinion and not that of any organization Go Bucs Pete Schwab From: Sprinklerforum [mailto:sprinklerforum-boun...@lists.firesprinkler.org] On Behalf Of Larry Keeping via Sprinklerforum Sent: Thursday, January 21, 2021 9:50 AM To: sprinklerforum@lists.firesprinkler.org Cc: Larry Keeping <lkeep...@plcfire.com>; John Denhardt <jdenha...@firesprinkler.org> Subject: RE: schedule 7 pipe? Good morning: I have been reading through this e-mail chain and I noticed a couple of references to the ASTM A-53 pipe spec. I stand to be corrected, but out that in all of the data sheets that I have ever seen, for "Schedule 7" or for any other listed sprinkler pipes, with wall thicknesses less than Schedule 40, are to the ASTM A135/A795 specs. The only data sheets that I am familiar with that meet the ASTM A53 spec. is for Schedule 40 pipe.
