Flange length

Flange length

Flange length

I'm new to Caesar II, so please bear with the silly questions.
I have just added a 300# flange to a 16" pipe.
The flange from Caesar is 149.225mm long.
However, ANSI 16.5 shows 144mm as the length of a weld neck flange (without the raised face).
Raised faces on 300# flanges are around 1.6mm (depending on supplier). I have checked several supplier catalogues and they show lengths (including raised faces) between 145.6 and 146.1
None of this matches the 149.225mm that Ceasar put in.. what is going on???

RE: Flange length

I'm not sure why, it probably includes length for the raised face and gasket between the flange pair.

Either way it's 5 mm...
