ISO 7005 (which AS 4331 is reproduction of) also includes European DIN flanges PN6 / 10 / 16 / 25 / 40 which were previously  DIN 2501-1 and BS4504. The following charts are for reference use only. The most common flanging used in Australia in oil, gas and mining is now ANSI flanging to ANSI B16.5. QUICK REFERENCE FLANGE CHARTQUICK REFERENCE FLANGE CHART www.worldwidemetric.com Copyright 2013. in.

Increasingly European PN rated flanges are also specified in BS4504 as well as AS4331 and EN 1092-1. PVC & HDPE BACKING FLANGE DIMENSIONS Bolt Size Size D1 PCD B D D D1 B PCD No. B.C. HOLES O.D. As the new pressure ratings are slightly higher the flange thicknesses have slightly increased. Wide Flange Beam Dimensions Chart for sizes, dimensions and section properties of steel wide flange beams. Table C, J to R, no longer exist, PN16 is the same drilling as Table D, PN21 is the same as Table E, PN35 is the same as Table H. AS4331 covers PN2.5 to PN420 and the sizing and drilling used is a replication of ISO 7005-1 which in turn is a metricated equivalent of ASME B16.5 class 150 to 2500. The charts show the dimensions of ASME B16.47 large size flanges class 150, 300, 400, 600, 900 (from 26 to 60 inches in diameter). ‘NB’ (Nominal Bore) is also sometimes used when referring to valve sizes. (1)- Bolt lenghts are calculated based on bolting one WN to one Blind. Forged steel flanges, ASME B16.5, are made in seven primary ratings: A Class 300 flange is rated to a higher pressure than a Class 150 flange, because a Class 300 flange is constructed with more metal and therefore can withstand more pressure. Below is an example of a flange NPS 12 (300NB) in all main pressure classes. Dimensions of ASME B16.47-A flanges class 150 All ASME B16.47 flanges dimensions are in inches 150 LB. 150# flanges dimension and weight- outside and inside diameters, bolt circles, numbers and diameters of bolts for Weld neck, Threaded, Slip-on, Lap joint, Socket weld and Blind flanges. Weights are in pounds. AS4331 has adopted ANSI drilling and sizes but uses PN rating classes. H mm Bolts No. Refer the Global Supply Line online slide rule above for differences. Flange Table Nominal Size 80mm (3 in) Height of raised face Thickness of flange Diameter of flange Bolt circle number Number of bolts. HOLES O.D. PN25 These flanges are the same as EN1092 but EN1092 also includes higher rated DIN based flanges. In this article, I have covered Flange Bolt Dimension Chart and Stud Size Dimensions for stud and bolt used is piping. Since ANSI 150 for instance has a CWP of 285 psi, so unlike the PN system the class is not related to CWP. 4331.1 – Steel Flanges (ISO 7005-1) EN1092-2 (DIN 2501/BS4504 based) PN2.5 / 6 / 10 / 16 / 25 / 40 and ANSI 150~2500LB ISO equivalent PN 20 / 50 / 110 / 150 / 260 / 420 Note in the case of AS4331.1/ISO 7005-1 ANSI equivalents they are not absolutely identical to ANSI but “deemed to comply and are designed to be interchangeable”. However GSL stocks high yield carbon steel API6A 45K weld neck flanges which are compatible with ASME A234 WPB fittings and A106B/API5LB pipe. (Refer to pressure/temperature charts at this website for various material types). Home > ASME ANSI Flange Sizes: ASME ANSI Flange Sizes. HL. Piping Class Ratings based on ASME B16.5 and corresponding PN rating: –. AS4087 is the new standard covering Table D to H.  The same drilling is specified but the PN rating system is used (PN16 to PN35). For example a Class 150 A105 flange is rated to approximately 270 PSIG (1861 KPA) at ambient temperature, 180 PSIG (1241 KPA) at approximately 400ºF (204ºC) 150 PSIG (1034 KPA) at approximately 600ºF (315ºC), and 75 PSIG (517 KPA) at approximately 800ºF (426ºC). There are many common flange standards and these flange tables cover the most commonly found i.e. World Wide Metric Inc. All Rights Reserved. HOLES O.D. For any temperature below -29ºC, the rating shall be no greater than the rating shown for -29ºC, depending on materials the rating can be lower. FLANGE DIMENSIONS - JIS D = Flange diameter n = Number of bolt holes Hcd = Hole circle diameter d = Diameter of bolt holes JIS 5K JIS 10K JIS 16K JIS 20K DN INCH D Hcd d BOLT n D Hcd d BOLT n D Hcd d BOLT n D Hcd d BOLT n mm mm mm mm 15 1/2 80 60 12 … Additional factors are that flanges can be constructed from different materials, such as stainless steel, cast and ductile iron, alloy steel, carbon steel, etc. In RF Stud Bolt Length mm RF Mach. Refer to our Flange Chart – ‘Online Slide Rule’ above for flange dimensions. AS4087 is an update of AS2129, however AS2129 is still widely used so it has not been deleted as a standard, however, it now only covers AS table D to H. AS4087 is the latest standard for BS table D to H, the same drilling is used but the new PN pressure rating system has been adopted. K mm Hole Diam. For ANSI 150 to 2500 class flange pressure/temperature ratings refer to the forged pressure/temperature ratings showing in the following link. Class 150: PN 20 During a dimensional inspection of slip on flange, you should check for Outer & Inner Diameter of body Flanges ; Nominal Pipe Size # Bolts or Studs: Dia of Bolts or Studs: Length of Stud # Bolts or Studs: Dia of Bolts or Studs: Length of Stud # Bolts or Studs: Dia of Bolts or Studs: Length of Stud: 1/16 RF: RTJ: 1/16 RF: RTJ: 1/4 RF: RTJ: 1/2: 4: 0.50: 2-1/4-4: 0.50: 2-1/2: 3: 4: 0.50: 3: 3: 3/4: 4: 0.50: 2-1/2-4: 0.63: 3: 3-1/2: 4: 0.63: 3-1/2: 3-1/2: 1: 4: 0.50: 2-1/2: 3: 4: 0.63: 3: 3-1/2: 4: … the cold working pressure of PN10 is 10 bar. Nominal Pipe Size NPS (inches) Class 150 Diameter of Flange (inches) No. AS2129 originates from BS10 and has been metricated. Cast (Grey) Iron thicknesses are shown in Cast Iron column. Steel Pipe Dimensions - Schedule 40; Steel Pipe Dimensions - Schedule 80 Flanges are standardized according publications from organizations like ASME, MSS, API and others. Class is also traditionally abbreviated CL or LB (verbally spoken as pound) or cross hash (#) but not psi as this can be misconstrued as the cold working pressure (CWP). Dimensions and properties for the taper flange I-beam: I-sections (taper flange) ('rolled steel joists') Flanges Table, Flanges Dimensions, Flanges Standard Chart, Flanges Size Chart | India. The below two tables are examples of two material groups according to ASTM, flange pressure-temperature ratings to ASME B16.5 – 2009. This example demonstrates that diameter of the raised face are all the same; but outside diameter, bolt circle and diameter of bolt holes become larger in each higher pressure class. Note that our PersonalFit Flex™ breast shields are available in four sizes – 21mm, 24mm, 27mm, and 30mm. PN stands for Nominal Pressure and roughly equates to the number of bar i.e. This is represented in the picture: Refer the Global Supply Line online slide rule above for differences. PN40 in. DIN Flanges Summary Chart Rated Pressure (in bar) (1 bar = 14.5 psi = 100 kPa) (1) flanges with rating class designations 150, 300, 400, 600, 900, and 1500 in sizes NPS 1/2 through NPS 24 and flanges with rating class designation 2500 in sizes NPS 1/2 through NPS 12, with requirements given in U.S. Petromet Flange Inc. is an ISO certified SABS 1123 Flange Orifice Flanges manufacturer & distributor in India. Dimension charts for Navy Flanges. Consequently in Australia most users simply just reference to original ASME B16.5 standards as this is already in use in Australia for the Oil, Gas and Mining industries and in fact in pressures above table E it has been the predominant standard in use for the last 30 years. I-shaped cross-section beams: Britain : Universal Beams (UB) and Universal Columns (UC) Europe : IPE. Nominal Pipe Size NPS (inches) Class 150 Diameter of Flange (inches) No. DIN based Steel/ BS4504 based on flanges covered by AS 4331.1/ ISO 7005-1 Flanges can withstand different pressures at different temperatures. Each material has a different pressure rating. Dimensions are in inches. LB is the origin of the Latin word Libra (weighing scale) a Roman unit of mass similar to a pound, hence this has been adopted as another way of saying Class.
