AS2129 flanges originates from BS10 and has been metricated. In some cases slightly larger bolt holes provide better clearance as metric bolts are specified in lieu of UNC bolts used by BS10. 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.
AS 2129 Australian Standard Flanges for pipes valves and fittings
Flanges for pipes, valves and fittings
SECTION 1 SCOPE AND GENERAL
1.1 SCOPE This Standard specifies requirements for circular flanges of nominal sizes
DN 15 to DN 3000, inclusive, and their bolting for use on pipes, valves, fittings and other
pressure-retaining equipment containing fluid at pressures up to 19 300 kPa and at
temperatures in the range −200°C to +525°C.
These AS2129 flanges are manufactured from carbon steel, carbon-manganese steel, alloy steel,stainless steel, grey iron, malleable iron, ductile cast iron*, or copper alloy.
This Standard is applicable to flanges for water, steam, compressed air, chemical and
petroleum plants, hydraulic piping and where other Standards require compliance with this
Standard.
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. As the new pressure ratings are slightly higher the flange thicknesses have slightly increased. Also the raised face dimensions (although rarely specified, flat face is mostly used) are slightly larger. 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. ISO 7005-1 also incorporates the superceded DIN 2533 & DIN 2501 flanges which AS4331 also incorporates (also mirrored in EN1092).

Table E is the most popular for applications with water.
All dimensions are specified in inches. |

These flanges are equivalent to the BS10 flanges, except that all dimensions are specified in mm.
In some sizes, bolt holes are slightly larger to give better clearance. |

| American National Standards Institute (ANSI) | ANSI 125

Higher numbers denote higher pressures.
Sometimes people use the word ‘Class’ instead of ANSI. e.g. an ANSI 150 flange might be called a ‘Class 150’ All dimensions are specified in inches. |

Engineers use the prefix PN (Pressure Nominale). e.g. a BA4504-16 flange will commonly be referred to as a PN16
Generally, a PN16 flange is designed to withstand pressures up to 16 bar. All dimensions are specified in mm. |
