PN 6 Flat Flange (DIN 2573)

Flat flanges manufactured to DIN 2573 in ST 37.2 carbon steel, rated at PN 6. Dimensions and bolt-hole drilling conform to DIN 2573 tables for this pressure class. Nominal size (DN) is the only configurable parameter; material and pressure class are fixed for this product line.

Typical applications include pipe and valve connections in low-pressure process piping systems. The dimensional table covers pipe outside diameter, flange OD (D), bolt circle (k), flange thickness (b), bore (d3), facing depth (f), bolt-hole diameter (d2), bolt size, bolt count, and reference mass per piece.
