DISTRIBUTION PIPING
The piping system shall conform to the requirements of NFPA 2001. In addition, the system
shall be securely supported with allowances made for agent thrust forces and thermal
expansion/contraction, and should not be subjected to mechanical, chemical, vibration,
corrosion or other damages.
Where explosions are likely, the piping shall be attached to supports that are least likely to
be displaced.
Although Argonite piping systems are not under continuous pressure, provisions should be
made to insure that the type of piping installed can withstand the maximum stress at
maximum storage temperatures.
If black pipe is used, insure that no rust flakes or particles remain inside the pipe as this
would ruin ceiling tiles and/or create a spray of rust/dust, which, in the event of protecting
an enclosure containing delicate equipment such as computers, would unnecessarily damage
the equipment.
Consideration should be given to the fact that the pipe network is open
under normal conditions and that humidity entering the pipe may result in
corrosion. The rust flakes will loosen from the inside of the pipe during a release
and may block orifices in the restrictor or in the nozzles, thus jeopardizing
the agent release/distribution. It is recommended that dirt traps be used
at the last nozzle in the line and at bends.
