AS2129 Flange of Table A Dimension and Weight

AUSTRALIAN STANDARD

AS2129 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.

NOTES:

(1) The minimum flange thickness in carbon steel flanges will be 12mm.
(2) Bore sizes to suit ASME B 36.10B36.19 pipe unless otherwise specified.
(3) Flanges are generally supplied flat faced.

AS2129 still in use but now only covers Table D to H. Table C now obsolete, Table J to T now replaced by AS4331.1 which is a replication of ISO7005-1 which in turn is equivalent to ASME 150-2500 class ANSI B16.5. AS4331.1 and ISO 7005-1 also incorporates previous DIN PN rated flanging. AS4087 is the new standard covering Table D to H. The same drilling is specified but the PN rating system is used (PN14 to PN35) and in some cases flange thickness varies slightly. AS4087 PN14 & PN16 are the same drilling as AS2129 Table D. AS4087 PN21 is the same drilling and rating as AS2129 Table F. AS4087 PN14 & PN16 is the same drilling as AS2129 Table D. AS4087 PN21 is the same rating and drilling as AS2129 Table F and PN35 is the same drilling as Table H. AS4087 specifies raised face in Ductile Iron
