Note: “C” Clamps are not acceptable to support rod hangers
Rigid pipe supports are required to support the “live load” of the pipe system
during discharge. Rigid bracing is required at each directional change, fitting,
tee and nozzle. All drops to 180° nozzles require back bracing in the opposite
direction of the discharge. Earthquake bracing shall be used where required
by local code. (Refer to ANSI B31.1 Power Piping Code for additional
information)
For additional information on pressure rating of pipe and fittings, plus
recommended pipe supports and hangers, refer to FSSA’s Pipe Design
Handbook, FSSA PDH-01.
All system piping shall be installed in strict accordance to system plans. If
piping changes are necessary, they must be recalculated on Fike’s Flow
Calculation Program.
4.5 NOZZLE INSTALLATION
Many nozzles look the same. Always verify the nozzle identification number (stamped on the closed end of the
nozzle) matches the nozzle part number listed on the system installation plans. All nozzle locations should be
within 1'- 0" (0.3m) of their intended locations on the system plans. Discharge Nozzles must be mounted in the
vertical position and can face either up or down.
CAUTION: The piping should be blown clear to remove chips, mill scale, or metal shavings before the nozzles
are installed.
