falnge design with tapped hole

[rezapayvar]

can anybody introduce some refrences for flange design with tapped hole?

How big a tapped hole where?

 

[rezapayvar]

supposed the same holes we have in ordinary flange design but they are tapped holes.

 

[SnTMan]

The bolt holes?

 

[rezapayvar]

the size of studs are 1".

I wouldn't consider it any different than a through-bolted design, other than the hole detail.

I don't think so.

Instead of 4 or 8 or 12 evenly spaced holes with an outside clamping force on to the back side of the full thickness of the flange, you now have 8 or 12 holes in the flange being pulled out by their threads. The flange will distort more, loosen the gasket seating forces.

rezapayvar, you may want to look at Studded Outlets for an example. I have no idea of what you are attaching the tapped flange to, but the attached link will provide some examples of proven designs.
