PN 16 Flat Flange (DIN 2501)

Flat flanges manufactured to DIN 2501 in ST 37.2 carbon steel, rated at PN 16. Dimensions and reference weights follow DIN 2501 as the primary standard; cross-reference data for EN 1092-1 and ISO 7005-1 is included where tabulated. Thickness (b, mm) and weight (kg/pc) are provided per nominal size. EN 1092-1 thickness values marked "c" reflect standard notation; mass entries may be absent for larger DN where source tables do not list values.
