Product Overview ORIFICE FLANGES CATALOG SECTION P How Daniel Orifice Flanges Provide Better Measurement Orifice flanges are one of the most economical means of measuring flow, and Daniel Orifice Flanges are manufactured to be the most accurate. Automatic machine tools enable Daniel to meet the most stringent of tolerances and recommendations for flanges as specified in ANSI B16.36, STEEL ORIFICE FLANGES, and ANSI/API 2530 (AGA #3), ORIFICE METERING OF NATURAL GAS, with careful attention given to tap location, bore smoothness, bolt and flange facings. Daniel Orifice Flanges are made of forged steel, A.S.T.M. A-105. Other materials are available on special order. FEATURES AND ADVANTAGES Bore Tolerances are well within the latest recommendations of the American Gas Association for .75 Beta ratio. Pressure Tap Hole Location is closely controlled. Tap hole centers are 15/16" from bearing faces of flanges, placing their centerline 1" from the face of the orifice plate when 1/16" gasket thickness is included. For 3" and smaller flanges: tap hole location tolerance is ± 1/64"; for 4" and larger flanges, the location tolerance is ± 1/32". Pressure Tap Holes -- Tap hole edges on the flange bore surface are carefully inspected to be free from burrs. All roughness is eliminated. Sizes are shown in the dimensional tables for this product. Flange Tap Connections -- Standard connections are 1/2" N.P.T. Other sizes on request.

How Daniel Orifice Flanges Provide Better MeasurementOrifice flanges are one of the most economical means of measuring flow, and Daniel Orifice Flanges aremanufactured to be the most accurate. Automatic machine tools enable Daniel to meet the most stringent oftolerances and recommendations for flanges as specified in ANSI B16.36, STEEL ORIFICE FLANGES, andANSI/API 2530 (AGA #3), ORIFICE METERING OF NATURAL GAS, with careful attention given to taplocation, bore smoothness, bolt and flange facings. Daniel Orifice Flanges are made of forged steel, A.S.T.M.A-105. Other materials are available on special order.
FEATURES AND ADVANTAGES
Bore Tolerances are well within the latest recommendations of the American Gas Association for .75 Betaratio.
Pressure Tap Hole Location is closely controlled. Tap hole centers are 15/16" from bearing faces of flanges,placing their centerline 1" from the face of the orifice plate when 1/16" gasket thickness is included. For 3" andsmaller flanges: tap hole location tolerance is ± 1/64"; for 4" and larger flanges, the location tolerance is ± 1/32".
Pressure Tap Holes -- Tap hole edges on the flange bore surface are carefully inspected to be free from burrs.All roughness is eliminated. Sizes are shown in the dimensional tables for this product.
Flange Tap Connections -- Standard connections are 1/2" N.P.T. Other sizes on request.
Raised Face -- Daniel Raised Face Orifice Flanges are made to conform to the standard raised facedimensions in accordance with the A.N.S.I. B16.5 Flange Piping Code for all pressure ranges.
Gaskets -- Two 1/16" thick precision die-cut asbestos gaskets are furnished with all Raised Face OrificeFlanges. Non asbestos gaskets are available on request. Note: When specified gasket thickness is other than1/16", flange pressure tap location will change.
Daniel offers orifice flanges/plates to meet the tolerances specified in API Chapter 14, Section 3, Part 2 (14.3).
These flanges will be the units shown with precision located knock out type dowel pins as shown in "DOWELPINS" section below. Due to the strict orifice to flange bore concentricity requirements of API 14.3, theaccompanying 520 paddle type orifice plates must also have similarly close tolerance machined O.D.'s.
It should be noted that due to the 14.3 concentricity requirements, slip-on and threaded orifice flanges cannotbe offered to this standard.
STAGGERED TAP HOLES: Daniel Orifice Flanges with staggered tapholes are available on request. These locations provide convenientclearance for instrument piping when valves must be installedadjacent to orifice flanges. Extra tap holes at bottom facilitate drainagewhere condensate is present.
DOWEL PINS: Alignment dowel pins of the knock-out type arefurnished on request on all Raised Face Orifice Flanges. These dowelpins assure correct alignment of the flange bores as well as centeringthe orifice plate within the flange bore.
METER TUBES: Daniel Orifice Flanges may be purchased complete with meter tubes which meet A.G.A.,A.N.S.I., and A.S.M.E. requirements. These precision built metering units provide reliable flow measurementin most any application. For details see Daniel Meter Tube Catalog.

Orifice Bore Calculations
ORIFICE BORE CALCULATIONS
The Daniel Orifice Calculation Department is a separate engineering branch responsible for the fast andaccurate calculation of orifice plate bores. The computerized department utilizes the latest published tradestatistics to figure and verify calculations. Their calculations are recorded on a reproducible data sheet fromwhich a copy is made and sent to the customer. The original is kept on file for 5 years. To insure promptcalculations, information relative to either gas, liquid or steam flow should be furnished.
Orifice Plate Bore Calculations
Daniel maintains one engineering section for calculation of orifice plate bores, furnishing them on reproducibledata sheets. The following data should be furnished when ordering calculations:
Meter differential range.1. Is the orifice to deliver maximum flow at the above differential pressure? If otherwise, please specify.2. In liquid flow, is flow volume at operating temperature desired, or at some other base temperature?3. In liquid or steam flows, what type meter is being used? Liquid over mercury or dry (mercury-less)meter?
4.
Tag, identification or item number.5. Fluid being measured.6. Operating temperature in degrees F.7. Operating pressure in Lbs. per square inch.8. Flow rate.9. . Specific gravity or density.10. . Viscosity, at the operating conditions.11. . Barometric pressure.12. . Pressure base.13. . Temperature base.14. . Liquid seal and its specific gravity.15. . Pipe inside diameter, or pipe schedule.16. . Orifice plate material.17. . Orifice flange rating and facing.18. . Pressure tap location. Flange? Radius? Vena Contracta? Pipe?19.
