What the other Sornsin brother called "mini-dams" a decade ago on this Forum. Being from Fargo, ND, and growing up the son of a sprinkler contractor, I'll assume he understands a bit about dry systems.

I could see where they might think this would become a potential weak point corrosion issue later on. -----Original Message----- From: sprinklerforum-boun...@firesprinkler.org [mailto:sprinklerforum-boun...@firesprinkler.org] On Behalf Of Brad Casterline Sent: Friday, October 26, 2012 1:18 PM To: sprinklerforum@firesprinkler.org Subject: RE: Stainless Steel Pipe I know George, and it is not illegal! Several years ago I tried to reason out why the Corp of Eng stopped allowing roll grooved galvanized-- I gave up and started asking sprinkler people-- the best I got was that roll grooving deforms the inside wall and the galv flakes off. A good fab shop would limit the problem by cleaning and spray galving the ends, but in the hustle-bustle of C.O.J. and field roll groove, the same amount of QC might not happen. Since we cannot cut groove thinwall, all galv for the Corps ends up S40. Are there any portable cut-groovers around anymore? -----Original Message----- From: George Church [mailto:g...@rowesprinkler.com] Sent: Friday, October 26, 2012 1:07 PM To: sprinklerforum@firesprinkler.org Subject: RE: Stainless Steel Pipe There's a heckuva lot of roll grooved galv S10 installed in sprinkler systems. We have 7 miles of it in one freezer that comes to mind.....with TriSeals, of course. George L. Church, Jr., CET Rowe Sprinkler Systems, Inc.

Nobody wants any 'stainless flakes' clogging up their concentrate lines :) -----Original Message----- From: mphe...@aerofire.com [mailto:mphe...@aerofire.com] Sent: Friday, October 26, 2012 12:12 PM To: sprinklerforum@firesprinkler.org Subject: Re: Stainless Steel Pipe Nope. It's stainless throughout the wall thickness. It's also more malleable than carbon steel so it roll grooves just fine.

Assuming stainless is like galvanized, it should be Cut Grooved only? -----Original Message----- From: mphe...@aerofire.com [mailto:mphe...@aerofire.com] Sent: Friday, October 26, 2012 11:00 AM To: sprinklerforum@firesprinkler.org Subject: Re: Stainless Steel Pipe Yes Mark at Aero ----- Original Message ----- From: Brad Casterline [mailto:bcasterl...@fsc-inc.com] Sent: Friday, October 26, 2012 03:51 PM To: sprinklerforum@firesprinkler.org <sprinklerforum@firesprinkler.org> Subject: Stainless Steel Pipe Can S.S. pipe be grooved? 2", 2.5", 3", for foam concentrate. thanks, Brad Casterline, NICET IV Fire Protection Division FSC, Inc.
