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. 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. 150 LB. AS2129 originates from BS10 and has been metricated. API6A flanging is used in Australia in oil drilling and wellhead systems. EN 1092-1 is for steel flanges, EN 1092-2 is for iron flanges, EN 1092-3 is for alloy flanges, EN 1092-4 is for aluminium alloy flanges. Consequently in some sizes flanges are thicker to bring the rating up to the required PN rating. 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).

Dimensions of ASME B16.47-A flanges class 150 All ASME B16.47 flanges dimensions are in inches PN stands for Nominal Pressure and roughly equates to the number of bar i.e. Consequently metric sizes are stated as ‘DN’ (Nominal Diameter) in mm. PN ratings do not provide a proportional relationship between different PN numbers, whereas class numbers do. PN is the rating designator followed by a designation number indicating the approximate pressure rating in bars. Additional factors are that flanges can be constructed from different materials, such as stainless steel, cast and ductile iron, alloy steel, carbon steel, etc. API ratings range from 2,000 to 20,000 psi (cold working pressure). In some cases slightly larger bolt holes provide better clearance as metric bolts are specified in lieu of UNC bolts used by BS10. However there are a number of factors that can impact the pressure capability of a flange. PN10 ANSI, PN and the old British BS10 Table D to K.
