flange bolt tightening torque
(OP)
Hi All,
I want to tighten the bolts connection between pipe flange and butterfly valve flange. Details as follows:
Valve size : DN2200
BOLTS: M56 X 52 Nos. - A2 hexagonal bolts
8mm thick rubber gasket is used in between valve and pipe flanges.
Can any one tell me how much torque need to be applied to tighten the bolts? If possible with a calculation for my future reference.

Thanks for your reply.
I can see that all gasket manufacturers specified bolt torque only till DN1000.
But I want for higher sizes like DN2200, 2600,3000.
Pls suggest how to proceed.
