Flat Flange Compared with the flange with neck, the plate flange can be divided into carbon steel plate flange, stainless steel plate flange and alloy steel plate flange according to the material. The structural form of flange includes integral flange and unit flange. Flat flange produced by hengdaxin pipe fittings Standard system for flat flange 1) Nominal pressure: 0.25mpa~42.0mpa a. Series 1: pn1.0, pn1.6, pn2.0, pn5.0, pn10.0, pn15.0, pn25.0, pn42 (main series) b. Series 2: pn0.25, pn0.6, pn2.5, pn4.0 The flange sizes of pn0.25, pn0.6, PN1.0, pn1.6, pn2.5 and pn4.0 belong to the European flange system represented by the German flange, and the rest belong to the American flange system represented by the American flange.
