Compared with neck flanges, plate Flanges can be divided into carbon steel flat flanges, stainless steel plat flanges and alloy steel plat flanges according to their materials. The structure of the flange includes integral flange and unit flange.
Flat flange standard system
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, PN4.0 have a total of 6 grades of flange sizes belonging to the European flange system represented by German flanges, and the rest are American laws The American flange system represented by Lan.
