thickness calculation for API Double studded Flange (DSA)

[petrotesting taha]

Dear All

I looking to machining Double studded Flange (DSA) 4 1/16 5000 psi x 4 1/16 10000 psi using the 4130 AISI raw material according to API spec 6A.
The thickness for each side is mentioned in the API stander ; please let me know who to calculate the totale thickness for DSA .
thanks

Typical the DSA thickness is the size of the larger flange. You need to take into consideration the drill and tap depths. On some configurations such as the 4-5k x 4-10k, the drill and tap depths will intersect with each other.
