EN1092-1 1.4404 Type11 Stainless Steel Forged WNRF Flanges
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.
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.

Grade 316L, the low carbon version of F316L pipe flange has
immunity against sensitisation, otherwise known as grain boundary
carbide precipitation. Thus, the Gr F316L is extensively used in
heavy gauge welded components, where the wall thickness can be over
6mm. The austenitic structure in the astm a182 f316l also gives
this grades excellent toughness properties ,that can be witnessed
at to cryogenic temperatures.
