What is the nominal diameter of a 10” flange? Some say it’s DN300, while others say it’s DN250 – which one is correct? If any expert could provide a standard table, I would be extremely grateful! !

As a rough estimate, using 1 inch = 25 millimeters. So 10 inches = 250 millimeters. So for DN250

There’s no doubt about this; it’s DN250, and you can find out by doing a search online.

Without a doubt, it’s the DN250 that everyone is talking about

It must be DN250; the nominal diameter can be chosen based on the data provided for floor 8: lol
