DN 1050 Flange Info

DN 1050 Flange Info

DN 1050 Flange Info

(OP)
I have a vendor dwg for a vessel that calls out DN 1050 flange. We know that 1050 is the O.D. of the pipe in millimeters, but we can't find the bolt circle and diameter on the vendor dwg. So we looked up info for DN 1050 flg but can't find an exact match for a "DN 1050 flange", can someone enlighten us on this standard......Thanks

RE: DN 1050 Flange Info

PiperFe,

DN1050 definitely does not indicate any dimensional standard. It only indicates the Nominal Diameter to be 1050 millimeters.
Your flange appears to be specially taylored for this application, not engineered to standard dimensions.

I would suggest the clarify the following:
Do you have any pertaining drawings showing "nozzle details"?
Do you have any spare gaskets in your warehouse, that may indicate the dimensional standard?

Hi!
DN 1050 flange maybe is 42" flange. Looking for more information on your drawings.
If that is, I think you can find the answer in ASME B16.47.
Series B always be uesed on vessels.
