4.2 DISCHARGE PIPING CONNECTIONS
The discharge piping is connected to the discharge valves in the various manners that follow. A basic installation
would involve direct connection to the valve via a pipe union or grooved coupling to facilitate removal of the
container for service purposes. More advanced installations will be accomplished by using a discharge manifold
to join multiple containers into a common piping supply network.
Refer to the sections that follow for additional information regarding pipe and fitting materials, installation
requirements, configurations, etc.
4.2.1 1" (25 mm) VALVE CONNECTIONS
The 1" (25 mm) valve used on the 20, 35, 60 & 100 lb. (8, 15, 27 and 44 L) containers has an Adapter Nut with 1”
NPT female threads that accept 1" NPT male threaded pipe. Prior to installing the discharge piping, remove the
Adapter Nut and coat the 2” (50 mm) straight threads of the container valve body with teflon tape or thread
sealant and replace the Adapter Nut.
IMPORTANT: Remove the Baffle Plug before installing the discharge piping to the Adapter Nut. The Baffle Plug
is an anti-recoil device that is required to be installed whenever transporting or handling charged
containers that are not connected to the discharge piping.
A pipe union should be installed close to the adapter nut. This makes removal of the container for service
purposes much easier.
4.2.2 2-1/2" (65 mm) VALVE CONNECTIONS
The 2-1/2" (65 mm) valves used on the 125 & 215 lb. (15 & 90 L) containers have 2-1/2" (65 mm) grooves
machined into the outlets of the valves. The transition from the grooved outlet to pipe thread is made through the
use of an adapter nipple (supplied by Fike) that receives 2-1/2" (65mm) female pipe thread.
It is not necessary to supply a pipe union after the grooved coupling to facilitate removal of the container for
service or maintenance purposes.
IMPORTANT: Remove the Baffle Plate located inside the grooved coupling before connecting the discharge
piping to the container. The Baffle Plate is an anti-recoil device that must be installed whenever
transporting or handling charged containers that are not connected to the discharge piping.
