Brad, Could their reasoning be because with cut groove there isn't a "bump" in the pipe to potentially trap the small amount of water? I could see where they might think this would become a potential weak point corrosion issue later on.

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:[email protected]] Sent: Friday, October 26, 2012 1:07 PM To: [email protected] 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.

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: [email protected] [mailto:[email protected]] Sent: Friday, October 26, 2012 11:00 AM To: [email protected] Subject: Re: Stainless Steel Pipe Yes Mark at Aero ----- Original Message ----- From: Brad Casterline [mailto:[email protected]] Sent: Friday, October 26, 2012 03:51 PM To: [email protected] <[email protected]> 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.
