Tech Talk

NEW FORMAT REQUIRED FOR HYDRAULIC CALCULATIONS
If you are operating under the 2007 edition of NFPA 13, Standard for
the Installation of Sprinkler Systems, you'll likely need to update
your software for hydraulic calculations. Effective January 1, 2008,
the format of the hydraulic information, including the order of the
forms, must be provided as dictated in Section 22.3.5 of the 2007
edition of NFPA 13. The information from the hydraulic calculations
is not new. The new requirement standardizes the format in which the
information is presented to provide consistency from each computer
program or set of hand calculations to aid the plan reviewer or
Authority Having Jurisdiction in the plan review process. The
software providers for hydraulic calculation programs participated in
the development of the output format, so they are aware of the
requirement. Check the building code that has been adopted by your
state or local jurisdiction to verify the applicable version of NFPA
13 that is in effect. The NFPA 13 edition in effect could be one or
two cycles behind the most recent edition. For example, the
International Building Code (IBC) 2003 edition references the 1999
edition of NFPA 13, IBC 2006 edition references the 2002 edition of
NFPA 13, and the 2006 Life Safety Code(r) references the 2002 edition
of NFPA 13. Also be aware that local amendments can specify the
edition of NFPA 13 that is in effect. If you aren't yet applying the
2007 edition, you may want to check the implementation schedule.
GALVANIZED PIPE - WHEN IS IT REQUIRED FOR USE IN NFPA 13 APPLICATIONS?
There is some misconception that all dry pipe systems are required to
have galvanized piping. Not so according to the 2007 edition of NFPA
13. Dry pipe systems can be black steel except for a few
applications. The dry pipe system piping must be corrosion resistant
or internally galvanized when small orifice K-factor 4.2 sprinklers
are used according to Section 8.3.4.3. Dry pipe systems and preaction
systems using large drop sprinklers requires internally galvanized
pipe according to Section 8.4.7.2. Water cooling towers under the
Special Occupancy Requirements Chapter in Section 21.24.2.10.1
requires the piping, fittings, hangers, braces, and attachment
hardware including fasteners shall be hot-dip galvanized steel or use
other materials that have a superior corrosion resistance. Two other
sections that require galvanized pipe is Section 6.9.3.3 that requires
all piping to water motor-operated devices shall be galvanized or
brass or other corrosion-resistant material acceptable under this
standard, and Section 6.9.3.3 that piping between the sprinkler system
and a pressure-actuated alarm-initiating device shall be galvanized or
of nonferrous metal or other approved corrosion-resistant material.
Thus there is no requirement carte blanche that all dry pipe system
must have galvanized piping.
NFPA 14 - STANDARD FOR THE INSTALLATION OF STANDPIPES AND HOSE SYSTEMS
IS ACCEPTING PROPOSALS
It seems like the 2007 edition of NFPA 14 just arrived, but NFPA is
accepting proposals for the 2010 edition of NFPA 14. The Proposal
Closing date is May 30, 2008. Now is the time to review the document
and submit new requirements, changes, or clarifications for the
committee's consideration.
