ISO/ANSI Flange
ISO/ANSI Flange
(OP)
I'm having a tricky time trying to find the name of a flange that can bolt to both an ANSI flange and an ISO flange of the same nominal size. I've seen them and they look sort of like a flower, but I've also seen a variety that consist simply of a double set of bolt holes, one of each bolt hole diameter. Would anyone have ever run across this type of flange would know the name? Anyone know where I might be able to purchase one?
Thanks for the help.

Conversion flange? (or "metric conversion flange")
ISO/ANSI flange?
ISO conversion flange?
Adapter flange? (ISO adapter flange)
I can't remember either. I've seen them too, but I'm not sure they were pipe flanges. It might have been a motor-to-pump flange or some other flanged connection, but not a code piping connection.
It may have been flanges on a water pump for Class 150 service or something lightweight like that. Yeah, hazily remembering, I bet that was it, water pump flanges. But they would have been on the pump itself, from the manufacturer, not separately supplied articles for making pipelines. Were they German pumps, or Weir from Australia? Hmmm . . . . .

One end is an ANSI flange of the proper schedule and rating and material, the other end matches your (pump or filter or tank or hose or eqpt flange or whatever.)
Second spool (same length!) matches the ISO/Euto pressure flange, with its oposite end matching your piece of eqpt/tank/hose/etc.
Cost of the spool pieces is minor compared to a environmental/OSHA/explosive hazard caused by mis-matched over-drilled high pressure flanges.
