Dear all,

Can you pls give your thoughts in Calculating the requirred wall thickness of a Pipe after its bend accoring to ASME B31,8 code.

Since i can see a direct formula in calculating the Min. WT after bend in ASME B31,3 ( 304,2,1) code taking into account the Intrados and extrados from the Radius of the bend.

But in B31.8 there is not specific foruamla and just I deducted some mill tolerance percentage from the Straight pipe Wall thicness.

Pls give your sugesstion on how to calculate this.

Best regards,
Mani.
