Single Chamber
Single Chamber
Fittings
are
the most widely accepted means for flow
measurement of gas and other hydrocarbons in the oil, gas &
petrochemical industry.
Single
Chamber Features:
● Fast inexpensive orifice plate change
● Meets or exceeds all industry specifications.
● Telemetry capabilities in sizes 3 4 & 6 Consult Sales
● Single Chamber
fitting provides both cost and time saving opportunities to the
operator.
● One piece body allows operator the freedom to remove orifice plate
without the time consuming operational steps associated with Orifice
Flange Unions.
● The orifice plate seal is HNBR bonded to a stainless steel metal
insert. This insert retains seal shape, ensuring no protrusion into the
bore. The Seal Ring
design provides a positive seal against the orifice plate and the
upstream fitting seat. This conforms to AGA 3/API 14.3 requirements.
Single
Chamber Fitting Applications:
● Gas Gathering
● Compressor Stations
● Onshore Offshore Production
● Coal-Seam Gas Measurement
● Gas Distribution
● Gas Transmission
● Process Gas Plant
Fitting Pressure Ratings:
