Australia Flange AS2129 Table D Stainless Steel Flanges

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.

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 ISO 7005-1 also incorporates the superceded DIN 2533 & DIN 2501 flanges which AS4331 also incorporates (also mirrored in EN1092).

There are several standards for flanges, and we deal with four of them;
British Standard – BS10 Table D

Table E

Table F

Table G

Table H

Table J

Table K

Table E is the most popular for applications with water.

All dimensions are specified in inches.

Australian Standard – AS2129 Table C

Table D

Table E

Table F

Table G

Table H

Table J

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

ANSI 150

ANSI 300

ANSI 600

ANSI 900

ANSI 1500

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.

British Standard – BS4504 BS4504-6

BS4504-10

BS4504-16

BS4504-25

BS4504-40

BS4504-64

BS4504-100

PN6

PN10

PN16

PN25

PN40

PN64

PN100

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.
