Flat Welding Flange EN1092-1 TYPE 01/A 1.4307 1.4404 DN50/60.3 DN100 PN10/16
Flat Welding Flange EN1092-1 TYPE 01/A 1.4307 1.4404 DN50/60.3 DN100 PN10/16
YUHONG'S each classification is labelled with the lettering EN 1092-1 (i. e. the reference standard) followed by a two-digit number indicating the construction of the flange, and a letter which indicates the kind of sealing surface of the flange.
The labelling on the side of all kinds of flanges includes not only the lettering EN 1092-1 TYPE___, but also information concerning PN, DN and casting of the raw material used for the creation of the flange.
Europe countries mainly install flanges according to standard EN 1092-1 FLANGE STANDARD (forged Stainless or Steel Flanges). Similar to the ASME flange standard, the EN 1092-1 standard has the basic flange forms, such as weld neck flange, blind flange, lappedthe flange, threaded Flange (Thread ISO7-1 instead of NPT), weld on collar, pressed collars, and adapter flange such as flange coupling GD pressfittings. The different forms of flanges within the EN 1092-1 (European Norm Euronorm) is indicated within the flange name through the type.
