All dimensions are in millimetres.
The PN 16 plate-flange table also applies to DN 10–175 at PN 10. Weld-neck flanges share the drilling and raised face of the plate table.
IS 6392 drilling follows the ISO/DIN metric series, so IS 6392 flanges generally mate with EN 1092-1 / DIN flanges of the same PN — check the raised face and thickness for your flange type.
