Restriction/Flow Orifice Plate Dimensions

[Weegie]

Hi,

I'm looking for info/spec numbers for the manufacture of Restriction/Flow Orifice Plates.
I've found lots of useful websites with sizes/dimensions for imperial sizes(typically 2" pipe ANSI 150 & upwards)
I'm looking for the metric equivalent in DIN/PN pipe size/class.

Thanks.

Why not just make up what you require? Once you know what size orifice you need, the thickness can be calculated using equations from Roark, for example.
Cheers,
John

JohnGP,

Thanks for the reply.
I'm looking for actual dimension details for O.D.'s of the metric restriction/flow orifice plates. There's lots of info for imperial size on the web but, I can't find details for metric.
I've put a call in for ISO 5167 and will look at that.
My other alternative for O.D. sizes would be to look at metric gasket dimensions.

Many thanks.
