Maryland Metrics Technical Data Chart Diameters Drilling of DIN Flanges ( mm ). Flange Nominal Diameter, Pressure Rating (PN). D = Flange diameter n = Number of bolt holes. Hcd = Hole circle diameter d = Diameter of bolt holes. Connecting dimensions according to DIN EN 1092-and DIN 2501-11). PN PN 1 PN 1 PN and PN 40.
Rated Diameter, d b, k, h d s, r, h d f, Number, Threa d Kg. Loose plate flange with weld on plate collar. DN stands for ‘Diameter Nominale’, it is a translation between imperial and metric.
Dimensions, Sizes and Specification of DIN Flange DIN Standard Flanges. Slip On Flanges Blind Flanges Welding Neck . Flange dimensions according to different PN are sometimes the same, e. ANSI 60 90 15flange thickness does not include raised. Steel flanges in this DN and PN may be supplied with holes. Below is a reference table for critical flange dimensions to help identify what standard you have. ISO 70(DIN), PN 19 15 M1 18.
PN PN 1 PN 1 PN 2 PN 4 PN6 PN 10 PN 16 PN 25 PN 320. Flange drillings in EN1092-are generally the same as BS45but EN1092-covers a wider range. In Australia the BS and AS flange standards are essentially the same but have been metricated.
Consequently metric sizes are stated as ‘DN’ . Flange dimensions and drilling to DIN 2501. Stainless Steel DIN26PNFlanges weight. All dimensions in mm (except where differently indicated).
