7-14.1 Selection of Piping Material
When selecting pipes fitted by the use of threaded fittings, compression fittings or
welded fittings, care must be taken to insure a smooth internal installation. In addition,
the pipe selected must be of a noncombustible material with physical and chemical
characteristics such that its integrity during discharge can be predicted with reliability.
It is important that the pipe selected have minimal internal corrosion, which
can clog up discharge nozzles. Special corrosion-resistant materials or
coatings shall be required in severely corrosive atmospheres. The selected
piping schedule shall always be in accordance with the requirement of the
authorities having jurisdiction.
Also important is that the interior of the pipe be free of burrs that may be
present after cutting and threading.
A variety of pressure rated piping can be used: carbon steel, stainless steel 304 or
stainless steel 316. Wall thickness of the selected pipe shall be calculated in
accordance with ASME B31.1, Power Piping Code.
The internal pressure used for this calculation/selection shall be the systems maximum
peak pressure calculated at the maximum operating temperature. In piping sections
where a valve arrangement introduces a section of closed piping, such sections
shall be equipped with a pressure relief device. Closed pipe sections are to be given
attention equal to that given the discharge manifold.
7-14.2 Estimating Pipe Sizes
The values listed in Table 7-9 are approximate flow rates for estimating pipe sizes.
The Kidde Fire Systems Argonite Flow Calc program must be used to verify
exact pipe sizes, nozzle orifices and restrictor sizes for all system designs
and installations. See Argonite Flow Calc Manual, P/N 38-KFSARG-100. Failure
to use the Argonite Flow Calculation Software could result in system
malfunction, thereby causing property damage, personal injury and/or death.
7-15 PIPE HANGERS AND SUPPORTS
 All supports and parts thereof shall conform to the requirements for pressure piping
ASME B31.1, latest issue, and NFPA 2001.
 Conventional hanger design which is generally accepted as good practice, using
standard stock or production units as manufactured by recognized reputable
manufacturers, shall be utilized whenever possible but within the limits as set forth
hereafter.
 All piping must be solidly anchored to walls, ceiling structure, or columns by angle
iron brackets, support struts, or equivalent brackets where longitudinal or lateral
sway may occur. Particular attention must be paid to the bracing of all piping changes
in direction, nozzle piping, and storage unit header piping.
 All piping must be securely anchored to rigid support. Pipe supports and parts shall
be steel and adequate to support the pipe in a sub-cold condition, and to allow for
free and ample movement for contraction except where anchored, thereby preventing
excessive stress. Pipe shall be supported and anchored as the piping system requires.
 Cast iron supports, half clamps, conduit clamps, malleable iron ring-type hangers,
single beam clamps, or C clamps SHALL NOT BE USED to support piping. Beam
clamps that grab both sides of the beam flange are acceptable, in addition to drilling
of or welding to the beams (if authorized by owner).
