Description - Swivel flange fitting, integrally PTFE
lined and flared.
Specification - Flanges to ASA150 or DIN PN10,
different pressure ratings of flanges to these specifications are also
available.
Note: DIN Standard PN10 and PN16 flange dimensions and
specifications are identical. Flanges are normally stamped PN10, but are
suitable to PN16 use if required.
Materials - Spigot in 316 SS, Ferrule in 304 SS,
Flanges either MS, Zinc Plated Mild Steel or in Grade 304 SS, except 1", 1 1/2"
and 2" PN10 flange in Grade 316Ti (1.4571) SS.
Maximum Working Pressures - These are defined by the
flange specification. For standard ASA150, the maximum working pressure is
16 Bar. For PN10, 10 Bar. For PN40, 40 Bar etc. Test Pressures
are 1.5 times the Maximum Working Pressure. (Exceptions: where the hose
MWP is less than the fitting MWP)

Adapting for Different Flange Sizes
To fit larger than nominal flange sizes
It may be necessary to fit a larger than nominal flange size to the hose, for
example 3" flange fitted to one end of a 2" hose, in which case it may also be
necessary to increase the diameter of the sealing face to the correct size for
the larger flange. This can be achieved by means of a flange adaptor as
shown.
To fit smaller than nominal flange sizes
Within limits, it is also possible to make up an assembly with a flange one
size smaller than the nominal size. The smaller flange is bored out and
fitted to the larger hose and if necessary, the flared diameter is reduced to
suit. Consult the supplier if a different flange size is required.
