2.1 Cylinder Assembly
e cylinder assembly consists of the cylinder, dip tube, and cylinder valve.
2.1.1 Cylinder
e FM-200® agent is stored as a liquid inside a welded steel cylinder. e cylinders are superpressurized
with dry nitrogen to a pressure of 360 psig (24.8 bar) at 70°F (21°C). Every cylinder has a minimum ll
density of 35 lb/ft
3
(561 kg/m
3
) and a maximum ll density of 70 lb/ft
3
(1121 kg/m
3
). e capacity of a
cylinder varies according to the design requirements and the Series designation (See Table 2.1.1 for a list
of available capacities).
Standard domestic cylinders are manufactured according to the requirements of the U.S. Department
of Transportation (USDOT) and Transport Canada
1
(TC) for compressed gas and are tted with an
identication label indicating the ll quantity of FM-200®. Each cylinder has internal neck threads to allow
for connection to the cylinder valve.
2.1.1.1 Rupture Disc
A frangible rupture disc is tted to the Lv Series cylinder body. It functions as an emergency relief device in
the event of excessive internal pressure within the cylinder. Its rupture point is between 850 psi (58.6 bar)
and 1000 psi (68.9 bar).
is feature is not found on the Sv Series or Mv Series cylinder. Instead, a rupture disc is located on the side
of Sv Series and Mv Series cylinder valve as detailed in sections 2.1.3.1 and 2.1.3.2.
