Flat flange standard system
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, 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 German flange, and the rest are American flange sizes. The American flange system represented by Lan.
