ABOUT THE SEAL POTS/CONDENSATE CHAMBERS |
|
Condensate chambers are used
as a
barrier between
the
main
line
and
the
secondary
instruments in
the
measurement
of
steam
or
other
vapors
which
condense
to a liquid state
insuring
compatibility
with
the
secondary
instruments. They can also be used to cool down very high temperature liquids. Seal pots are installed where the line fluid is corrosive or viscous to the extent where it cannot be permitted to contact the secondary instrument. (transmitter or gage) thereby acting as a liquid
barrier between the line fluid and the condensate. |

Seal pots/Condensate chambers are available in carbon steel, stainless steel,
P22 and
other alloy steel. Standard pipe sizes are 2" through 6" and pressure ratings
for
carbon
steel as indicated on the enclosed chart. Connection fittings are NPT or welded socket adaptors. Chambers can be hydrostatically tested
and
x-rayed upon request. ISO and ISA standards are typically followed unless otherwise specified.
Typical industry
applications include: refineries, power plants, chemical & petrochemical, steel plants and other process industries.
Installation can be either vertical or horizontal lines between the primary (Flow Meter) and the secondary (transmitter/gage) to act as steel or barrier to the line fluid permitting direct sensation of the flow conditions. Units should be mounted at the same level minimizing possible error that could arise due to unequal head of fluid in the connecting pressure lines.
Initial
sizing
of
the
required
level
in
the
seal
pots
is
somewhat
subjective.
The
basic
rule
of
thumb
is
that
the
level
in
the
chambers
should
equal
the
total
volume
of
condensate
in
the
transmitter
and
the sensing lines. This also complies with ASME requirements. Exact capacity is also contingent on a number of other issues including: relative humidity, Due point, pressure, flow rate, etc.
Standard
maintenance
includes draining/filling as necessary.
