Establishing Connections Sizes, Lengths & Bends
Typical Single Protected Enclosure Connections
Helpful Hints
To ensure adequate protective gas flow to the protected enclosure(s), all piping and tubing must be fully reamed.
Precautions must be taken to prevent crimping and other damage to protective gas piping and tubing.
When protecting multiple enclosures with a single enclosure protection system, the enclosures must be connected
in series from the smallest to the largest to ensure adequate protective gas flow.
Determining Enclosure Inlet & Outlet Connection Locations
Helpful Hints
If flammable gases are lighter than air, the inlet connection to each
enclosure must enter near a bottom corner. The outlet connection, for
the required enclosure protection vent or piping to an adjacent
protected enclosure, must exit near an extreme opposite top corner. If
flammable gases are heavier than air, inlet and outlet connections must
be reversed. In all cases, the most prevalent gas must determine the
location of inlet and outlet connections.
