EN 1092-1 Type 11 Weld Neck Flanges

March 8, 2021

The EN 1092-1 Type 11 flanges are weld neck flanges, which have the same function and usage as that of ASME B16.5. It can be joined to piping by a butt welding process. The EN 1092-1 Type 11 weld neck flanges cover all standard PN designations: PN 2.5, PN 6, PN 10, PN 16, PN 25, PN 40, PN 63, PN 100, PN 160, PN 250, PN320, and PN 400. Generally, they shall be made by a forging process.

Technical Drawing & Dimensions’ Denotation

EN 1092-1 WNRF drawing

A typical drawing of the EN 1092-1 Type 11 weld neck flange with raised face (RF).

The denotation of dimensions: D – outside diameter; K – diameter of bolt circle; n – number of bolting; d – diameter of bolt hole; A – outside diameter of neck; X – diameter of neck root; S – wall thickness; h – straight length of neck; H – overall length of flange; C – flange thickness; f – height of raised face; R – diameter of raised face.

EN 1092-1 Type 11 weld neck flanges may be furnished with a series of facings from Type A to Type H, of which raised face (RF, Type B) is most commonly applied. When raised face is furnished, the transition from the raised face to the flange face can be by radius or chamfer. The height of raised face f doesn’t change in different PN designations but only varies in different size ranges. When raised face is furnished, its height shall be included by the flange thickness C as well as by the overall length of flange.
