Flange table size quick reference and comparison guide.

Flange size charts according to NB (Nominal Bore Size), giving the flange diameter, Thickness and PCD (Pitch circle diameter) or diameter of bolt holes, Number of bolt holes and bolt diameter and length.

This flange data guide covers PN6, PN10, PN16, PN25, PN40, PN64, Table D, Table E, Table F, Table H, ANSI150Lb and ANSI300Lb,
