Question 10.11: A reverse flange is joined to a regular ring-type joint flan...

Structural Analysis and Design of Process Equipment

A reverse flange is joined to a regular ring-type joint flange to form a reducing connection. The total bolt-up moment is controlling and equal to $M_{0}$ = 2,613,000. The flange bore $B^{\prime}$ = 13.25 in.; the outside diameter A = 26.5 in.; and the flange thickness t = 5 in. What is the tangential flange stress at the hub and at the inside bore?
