In some cases slightly larger bolt holes provide better clearance as metric bolts are specified in lieu of UNC bolts used by BS10. Please see the dimensions and properties for the parallel flange I-beams below. Dimensions are in inches. If two flanges have the same bore size (example 6 inches), the same material (example A105), but two different pressure ratings (one flange is class 150, the other 300), the lower rated flange (class 150) will be smaller, lighter, and less robust than the higher rated flange (class 300). We offer a 36mm size in PersonalFit and PersonalFit PLUS only, but not in PersonalFit Flex. However the actual dimensions and bore sizes have not changed. Flange Table Nominal Size 80mm (3 in) Height of raised face Thickness of flange Diameter of flange Bolt circle number Number of bolts. Help identify turbo inlet flange bolt patterns and dimensions in mm. Class 2500: PN 420. 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. 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 rat… HL. HOLES 550 DIN JIS 720 665 20 X 27 745 680 20 X 33 795 720 20 … ‘NB’ (Nominal Bore) is also sometimes used when referring to valve sizes. Home > ASME ANSI Flange Sizes: ASME ANSI Flange Sizes.

API ratings range from 2,000 to 20,000 psi (cold working pressure). 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). The most common flanging used in Australia in oil, gas and mining is now ANSI flanging to ANSI B16.5. Thank You for subscribing to Hardhat Engineer.

AS 4331 is a reproduction of ISO 7005 which is based on the American and European flange systems. The following charts are for reference use only. 150 LB. PN20, PN50, PN110, PN150, PN260 and PN420 Steel flanges are “designed to be interchangeable” with flanges to American standards ANSI/ASME B16.5 and MSS SP44. There are many common flange standards and these flange tables cover the most commonly found i.e. The regular '!winch raised face of Class 150 and 300 flanges is incluaed in the minimum flange thickness given above, but other raised faces must be added thereto. Class 150: PN20 The standard method for specifying the dimensions of a American Wide Flange Beam is for example W 6 x 25, which is 6 inches deep with a weight of 25 lb/ft. In RF Stud Bolt Length mm RF Mach. PN is the rating designator followed by a designation number indicating the approximate pressure rating in bars.

Although the standards say they are identical, I notice some very minor flange thickness differences between ISO 7005 (AS4331) and EN1092. Refer the Global Supply Line online slide rule above for differences. Also the raised face dimensions (although rarely specified, flat face is mostly used) are slightly larger. Your Ebook will Open in New Tab. The below two tables are examples of two material groups according to ASTM, flange pressure-temperature ratings to ASME B16.5 – 2009. Flanges can withstand different pressures at different temperatures. PN50. ISO 7005-1 also incorporates the superceded DIN 2533 & DIN 2501 flanges which AS4331 also incorporates (also mirrored in EN1092). PN40 The number and diameter (mm) of the bolt holes for the example below of 300NB is: 12 x 25.4mm Class 150, 16 x 32mm Class 300, 16 x 34.9 Class 400, 20 x 34.9mm Class 600, 20 x 38.1mm Class 900, 16 x 54mm Class 1500 and 12 x 73mm Class 2500. 150 LB. Meaurements of all common flange tables including PCD, number of holes and flange diameter. ANSI, DIN, and JIS Flanges: Dimensions Pressure Class. Increasingly European PN rated flanges are also specified in BS4504 as well as AS4331 and EN 1092-1. Class 1500: PN260 Note column B. Petromet Flange Inc. is an ISO certified SABS 1123 Flange Orifice Flanges manufacturer & distributor in India. The bore is subject to the required schedule. Never say PSI as this can be confused with API 6B flanges which are rated by PSI (CWP). Wide flange beams are designated by the letter W followed by the nominal depth in inches and the weight in pounds per foot. K mm Hole Diam. ASME B16.47 SERIES A FLANGE DIMENSIONS CLASS 150.

In some cases slightly larger bolt holes provide better clearance as metric bolts are specified in lieu of UNC bolts used by BS10. AS2129 originates from BS10 and has been metricated. H mm Bolts No. Home > ASME ANSI Flange Sizes: ASME ANSI Flange Sizes. If your nipple diameter measures 24 mm, your recommended size would be 30 mm. HOLES O.D. API6A flanging is used in Australia in oil drilling and wellhead systems. In Australia the BS and AS flange standards are essentially the same but have been metricated. AS/NZS 4331 is identical with and has been reproduced from ISO 7005. B.C. ANSI based flanges covering AS 4331.1/ISO 7005-1 Consequently metric sizes are stated as ‘DN’ (Nominal Diameter) in mm. These flange tables cover flanges from 15mm (1/2") up to 600mm (24"). QUICK REFERENCE FLANGE CHARTQUICK REFERENCE FLANGE CHART www.worldwidemetric.com Copyright 2013. 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. ASME/ANSI B16.5 provides. PN10 EN 1092 evolved from DIN 2501 which became part of ISO 7005, then EN 1092 was created as the standard for DIN based flanges. PN25 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. (1)- Bolt lenghts are calculated based on bolting one WN to one Blind. For intermediate temperatures, linear interpolation is calculated by manufacturers.
