Standard System of Plate Flange

　　Plate flange relative to necked flange, 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 forms of flange are integral flange and unit flange.

　　Flange connection is an important connection mode in pipeline construction. Flange connection is easy to use and can withstand greater pressure. Dn80 Pn16 Industrial Carbon Steel Plate Flange are widely used in industrial pipelines.

　　Standard System of Plate 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

　　Among them, PN0.25, PN0.6, PN1.0, PN1.6, PN2.5 and PN4.0 are six grades of Plate flange sizes, which belong to the European flange system represented by the German flange, while the rest belong to the American flange system represented by the American flange.
