All true, bcoz there is distinction between seismic brace and seismic restraint (and seismic anything vs hangers). I felt like cheap shot bcoz I seem to recall something explicit myself- maybe in Definitions of an older edition.

It's getting blurry. Yes, a wrap-around is one means of seismic restraint, as are an additional rod hanger at 45° or splay wires or even a sway brace. But a restraint isn't a hanger, nor is it a seismic brace. Wrap-around U-hooks are a type of hanger that may qualify piping for an exception to the requirement for lateral sway bracing, but are not seismic braces per say.

This is a bit of a cheap shot, I know. A wrap-around u-hook is an acceptable hanger, and, if the legs are min 30 deg from vert, also seismic restraint. -----Original Message----- From: Brad [mailto:[email protected]] Sent: Tuesday, May 11, 2010 8:48 AM To: [email protected] Subject: RE: Are Seismic Braces considered hangers? 2007 3.11.1 -----Original Message----- From: Gobeli, Paul [mailto:[email protected]] Sent: Monday, May 10, 2010 4:30 PM To: [email protected] Subject: Are Seismic Braces considered hangers? Where in NFPA 13 or elsewhere does it state that a seismic brace is not a pipe hanger? I seem to recall this stated explicitly somewhere but cannot place it.
