Plate Flanges Free Sample 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 The plane flange has a gasket surface on the same plane as the bolt connection circle. Applications where flat flanges are used are usually where the mating flange or flange fitting is made from a casting. The common flange looks like a flat disc with inner hole and bolt hole, which is a kind of slip on the flange. Stainless steel flat flange is used in piping system to connect and connect pipes, valves, pumps, etc. Flanges are usually used as external or internal ridges or edges to connect various parts of the pipe and are easy to assemble and disassemble. The flat surface of stainless steel plate flange can make the whole surface of two flanges contact completely鈥?Flat face "stainless steel flange can only use full sealing gasket. This ensures complete and even contact between the two mating flangesPlate Flanges Free Sample website:http://www.gcflange.com/plate-flanges/
