                       Dual Chamber   

 

Dual Chamber Orifice fittings “fully conform” to the latest AGA 3/API 14.3 stringent requirements. They require no added uncertainty and provide accurate performance over the orifice plate beta ratio range from 0.1 to 0.75 within 0.5% flow accuracy to theoretical value. 

 

 

Fitting Pressure Ratings:


● ANSI Class 150 (285 PSI CWP)
● ANSI Class 300 (740 PSI CWP)
● ANSI Class 600 (1480 PSI CWP)

   *Note: Consult factory for higher ANSI ratings.


Standard Materials of Construction:


● Body Material - A-216 WCB / WCC *Note: Consult factory for any other fitting body material.
● Flange Ratings – ANSI Class 150 to ANSI Class 600 inclusive.
● Fitting End Connections – F x W, W x W, F x F 

    *Note: RTJ Flange facing available upon request.


Conforms to the following industry standards:


● AGA 3/API 14.3, ISO-5167
● ANSI B31.3, MSS SP-55, ANSI B16.5
● Fittings available for NACE MR-01-75-2000


Operating Range:


● Sizes 2” thru 12” ANSI Class 150, 300, & 600
● Temperature -20° F to 275° F (-29° C. to 120° C.)
● Schedule 40 and schedule 80 standard.
 

   *Note: Consult factory for larger sizes and other operating conditions.


Quality Check:


● Hydrostatic test 1-1/2 times rated CWP.
● Tested for positive plate seal, pressure tap integrity, seal protrusion and eccentricity

           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:


● ANSI Class 150 (285 PSI CWP)
● ANSI Class 300 (740 PSI CWP)
● ANSI Class 600 (1480 PSI CWP)
● ANSI Class 900 (2250 PSI CWP)

   * Note: Consult Sales for Higher ANSI Ratings
 

 

Standard Materials of Construction:


● Body Material - A-216 WCB/WCC *Note: Consult factory for any other fitting body material.
● Flange Ratings – ANSI Class 150 to ANSI Class 1500
● Fitting End Connections – F x W, W x W
● Raised Face Flange is standard for ANSI Class 150 to ANSI Class 600
● RTJ Flange is standard for ANSI Class 900
 

 

Conforms to the following industry standards:
