GENERAL INFORMATION
The "1S" series filters
are available in 1, 2 or 3 cartridge models. The filters are used by
the petroleum production industry in secondary recovery water
floods. The filter is normally placed at each individual input well
just ahead of the meter. The filters are ideal for many high
pressure, low volume glycol applications. The "1S" series is also
suited for other applications requiring low cost, durable, easily
operated filters. The head mounts directly in the flow line. The
filter may be mounted in any position. The body is connected to the
head by a two bolt grooved coupling and sealed with a double lip
gasket. Fluid enters one side of the head and is channeled to the
area around the cartridges. The fluid or gas passes through the
depth type cartridge into the center tube and out the side of the
head. The direction of flow, from dirty inlet to clean outlet, is
indicated by an arrow cast in the filter head. The "1S" series comes
in three basic models for various flow rates. All models are
available with epoxy lined bodies for added corrosion resistance.
Each model is equipped with a 1/4" internal pipe thread drain in the
bottom of the body.
STANDARD CONSTRUCTION FOR LIQUID AND GAS FILTRATION
"1S"
SERIES:
The cast ductile iron head has in-line 1" internal pipe
thread inlet and outlet connections. The tubular body is made of
carbon steel seamless tube. The head and body are connected by a two
bolt grooved coupling with a Buna gasket. Internal fittings, center
tube and retainer are made of brass for water applications. The 1, 2
and 3 cartridge models are available for 2000 psi working pressures
at a maximum temperature of 250° F.
"1SP" SERIES:
The "1SP"
series has all of the same construction features as the "1S" series
with the addition of epoxy lining to the tubular steel body. The
epoxy lined body should be used when the corrosion rate is great
enough to considerably shorten the life of plain steel units. "1SP"
models are normally used for salt water and mildly corrosive fluids.
