AS 2129 Flange Table D Manufacturer
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 2129 table D to H.
AS 2129 Table D flange is a trusted solution for a wide range of waterworks and general industrial applications. Manufactured according to the Australian Standard AS 2129, Table D flanges are designed for use at working pressures up to 350 kPa (approx. 3.5 bar).

This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee ME/1, Pressure Equipment Standard to supersede AS 2129—1994.
This Standard is the result of a consensus among representatives on the Joint Committee to produce it as an Australian Standard. Consensus means general agreement by all interested parties. Consensus includes an attempt to remove all objections and implies much more than the concept of a simple majority, but not necessarily unanimity. It is consistent with this meaning that a member may be included in the Committee list and yet not be in full agreement with all clauses of this Standard.
This Standard is derived from the British inch series flange Standard BS 10:1962, Flanges and bolting for pipes, valves and fittings. BS 10 was made obsolescent in 1970, however, it is still called up in British pressure equipment Standards. A 1992 survey of Australian industry showed that flanges in accordance with AS 2129 were still in great demand. As a result it was determined that AS 2129 should be revised and updated rather than being made obsolescent.
It is anticipated flanges to AS 2129 will remain in use for at least 50 years, particularly for replacement flanges. Consideration should be given to the use of alternative flanges, such as those to AS/NZS 4331, Metallic flanges (series), BS 4504, Circular flanges for pipes valves and fittings, (PN designated), ANSI/ASME B16.5, Pipe flanges and flanged fittings, and AS 4087, Metallic flanges for waterworks purposes.
