These flange tables include ANSI flanges, PN flanges and the old British Table C, D, E, F, H, J flanges. PN40 Lengths of alloy steel stud bolts do not include the height of the points. However in general industrial, commercial and waste/water industries AS2129 Table flanging is the most common. (1)- Bolt lenghts are calculated based on bolting one WN to one Blind. BS4504 is now obsolete and is replaced by EN 1092 which is listed in British Standards as BS-EN 1092. Thank You for subscribing to Hardhat Engineer. Refer the Global Supply Line online slide rule above for differences. Although the standards say they are identical, I notice some very minor flange thickness differences between ISO 7005 (AS4331) and EN1092.

For ANSI 150 to 2500 class flange pressure/temperature ratings refer to the forged pressure/temperature ratings showing in the following link.

EN 1092 evolved from DIN 2501 which became part of ISO 7005, then EN 1092 was created as the standard for DIN based flanges. Below is an example of a flange NPS 12 (300NB) in all main pressure classes.

PN40, Iron DIN/ BS4504 based on flanges covered by AS 4331.2/ ISO 7005-2 Class 900: PN 150 Also the raised face dimensions (although rarely specified, flat face is mostly used) are slightly larger. HL. AS2129 Still in use but now only covers Table D to H (Table C now obsolete), Table J to T now replaced by AS4331 which is a replication of ISO7500-1 which in turn is equivalent to ASME 150-2500 class ANSI B16.5). They are not identical but are “deemed to comply” with dimensions specified in ANSI/ASME B16.5 and MSS SP44 as appropriate. Consequently when the pressure goes down, the temperature goes up and vice versa. The ASME B16.5 - 1996 Pipe Flanges and Flange Fittings standard covers pressure-temperature ratings, materials, dimensions, tolerances, marking, testing, and methods of designating openings for pipe flanges and flanged fittings.. These flanges are the same as EN1092 but EN1092 also includes higher rated DIN based flanges. It is designed acc to SAE J518 and ISO 6162 standards, The one-piece flange clamp is cut into two parts, split flanges are used to clamping of hydraulic SAE flange adapter, or SAE flange hose fittings, or flanged head tubing. (BS4504 flanges were generally the same as the old DIN 2501 specification, but the new EN 1092 standard covers a wider range). 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. DIN based Steel/ BS4504 based on flanges covered by AS 4331.1/ ISO 7005-1 the cold working pressure of PN10 is 10 bar. In some cases slightly larger bolt holes provide better clearance as metric bolts are specified in lieu of UNC bolts used by BS10. The size of I-beams are determined by the weight it should be able to support and will differ from application to application and structure to structure. Nominal Pipe Size NPS (inches) Class 150 Diameter of Flange (inches) No. PN16 Class 150 loose flanges are thicker than integral flanges for sizes 31f,..inch and smaller. HE. in. Consequently metric sizes are stated as ‘DN’ (Nominal Diameter) in mm. However there are a number of factors that can impact the pressure capability of a flange. 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.

All Rights Reserved. In Australia the BS and AS flange standards are essentially the same but have been metricated. weld neck; slip-on; socket weld; threaded; lap joint; blind; flange dimensions for pipes ranging 1/2" to 24" - in classes ranging 150 to 2500. Please see the dimensions and properties for the parallel flange I-beams below. Dimensions and properties for the taper flange I-beam: I-sections (taper flange) ('rolled steel joists') 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. 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 Flange tables identify the type of flange you have. PN25 The bore is subject to the required schedule. 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. 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. PN stands for Nominal Pressure and roughly equates to the number of bar i.e. 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). Note column B. API6A flanging is used in Australia in oil drilling and wellhead systems. For intermediate temperatures, linear interpolation is calculated by manufacturers. AS4331 is a reproduction of ISO 7005 which is based on the American and European flange systems PN20, PN50, PN 110, PN 150, PN 260 and PN 420 steel flanges are “designed to be interchangeable” with flanges to American standards ANSI/ASME B16.5 and MSS SP44; they are not identical but are “deemed to comply” with dimensions specified in ANSI/ASME B16.5 and MSS SP44 as appropriate. ASME/ANSI B16.5 provides. PN ratings do not provide a proportional relationship between different PN numbers, whereas class numbers do.

The temperature shown for a corresponding pressure rating is the temperature of the pressure-containing shell of the valve or flange. Pressure/temperature ratings are maximum allowable working pressures allowed as per ASME B16.5 (published in metric and imperial). However GSL stocks high yield carbon steel API6A 45K weld neck flanges which are compatible with ASME A234 WPB fittings and A106B/API5LB pipe. Note that our PersonalFit Flex™ breast shields are available in four sizes – 21mm, 24mm, 27mm, and 30mm. HOLES O.D. Ratings range from PN2.5 to PN420. Weights are in pounds.

ISO 7005 (which AS4331 is a reproduction of) also includes European DIN flanges PN6/10/16/25/40 which were previously DIN 2501-1 and BS4504. There are many common flange standards and these flange tables cover the most commonly found i.e. ANSI was originally born from API, consequently in class 600 to 900 and 1500 ANSI the flanges are dimensionally equivalent to API 2,000, 3,000 and 5,000 in most sizes to ANSI 300NB (12”) API 13 5/8” but ANSI flanges being manufactured from lower yield strength carbon steel are rated to lower working pressure.
