Notes:

What is DN?	DN stands for 'Diameter Nominale'. Put simply, it is a rough translation of mm from imperial sizes, assuming that an inch is 25mm. We refer to a 12" flange as DN300, when in fact it is 304mm.	½"	DN15	6"	DN150
		¾"	DN20	8"	DN200
		1"	DN25	10"	DN250
		1¼"	DN32	12"	DN300
		1½"	DN40	14"	DN350
		2"	DN50	15"	DN375
		2½"	DN65	16"	DN400
		3"	DN80	18"	DN450
		4"	DN100	20"	DN500
		5"	DN125	24"	DN600

What is the PCD?

The PCD of a flange is one of the critical dimensions.

PCD (Pitch Circle Diameter) is the diameter of a circle that goes through each of the bolt holes.

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.
