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.
