1305 Series
2
The 1305 Series regulator inlet is installed directly
in a high-pressure, warm-gas flow line. Heat from
this line is transmitted through the fins in the inlet
adaptor. The temperature of the reduced pressure
gas is raised high enough to prevent formation of
condensate and regulator freeze-up.
Installation
After the regulator has been removed from the
shipping container, inspect the regulator for shipping
damage. Be sure the body and connecting pipeline
are free of foreign material. Coat external threads
with a good grade of pipe compound. The regulator
can be installed in any position. To position the
regulator, loosen the union nut (key 8, Figure 4) and
turn the regulator to the desired position. Tighten
the union nut.
Install these regulators as shown in Figure 2. Weld
a 1-inch (25 mm) pipe coupling on the high-pressure,
warm temperature supply line. Screw the inlet adaptor
(key 3, Figure 4) into this pipe coupling so that the inlet
and orifice are directly in the main flow line.
note
The main flow pipeline must be at least
3-inches (76 mm) in diameter.
