1 Product OverviewORIFICE FLANGESCATALOG SECTION PHow 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 , 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, Other materials are available on special AND ADVANTAGESBore Tolerances are well within the latest recommendations of the American Gas Association for .75 Tap Hole Location is closely controlled.

2 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 roughness is eliminated. Sizes are shown in the dimensional tables for this Tap Connections -- Standard connections are 1/2" Other sizes on Face -- Daniel Raised Face Orifice Flanges are made to conform to the standard raised facedimensions in accordance with the Flange Piping Code for all pressure -- Two 1/16" thick precision die-cut asbestos gaskets are furnished with all Raised Face OrificeFlanges.

3 Non asbestos gaskets are available on request. Note: When specified gasket thickness is other than1/16", Flange pressure tap location will offers Orifice flanges/plates to meet the tolerances specified in API Chapter 14, Section 3, Part 2 ( ).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 , theaccompanying 520 paddle type Orifice plates must also have similarly close tolerance machined ' should be noted that due to the concentricity requirements, slip-on and threaded Orifice flanges cannotbe offered to this 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.

4 Extra tap holes at bottom facilitate drainagewhere condensate is 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 TUBES: Daniel Orifice Flanges may be purchased complete with meter tubes which meet , , and requirements. These precision built metering units provide reliable flow measurementin most any application.
