Plate Flanges manufacturers Plate Flanges, Plate Flanges can be divided into carbon steel flat flange, stainless steel flat flange and alloy steel flat flange. The structural forms of flange include integral flange and unit flange. 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 Flat flange Our durable flat flange series can be used to seal the ends of pipes, valves or other connections. These flat flange have high tensile strength, with convex face and back, easy to install. Corrosion resistant, these flat flanges have high tensile strength and welding ability. Using high quality alloy as raw material makes our product series very durable. These flat flanges are available in standard sizes and can also be customized according to customer requirements. There are several types of sealing surface of Plate Flanges Concave convex surface (MFM) DN 1300 ~ 3000 DN300 ~ 3000 dn400 ~ 2000 DN300 ~ 800 Tenon surface (TG) DN 1300 ~ 3000 DN300 ~ 3000 DN300 ~ 3000 DN300 ~ 800 Full plane (FF) DN300 ~ 3000 DN300 ~ 3000 DN300 ~ 3000 DN300 ~ 800Plate Flanges manufacturers website:http://www.gcflange.com/plate-flanges/
