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.
