HI

We did an oval transition ring R55/R51, in order to adjust flanges 10"ANSI 2500 A 694 F60, with different groove sizes. In the valve side the flange groove is OK, but in the piping side the groove is below the specs . The groove size is 13/16" , but the same pitch diameter.
Also we performed a hydrotest for this job at a 5,860 psi, by 12 hours, and it was OK, but I need to be sure under normal operation conditions If I will not have problems with this transition ring. The diameter of the stud bolts are 2 1/2" and the torque is 4,400 pounds-feet.
Thanks is advance for your cooperation, I am enclosing a drawing of the flange and ring.

You may or may not have a problem, depending on the operation of the flange. For example, the operating and design conditions, including pressure AND temperature, external bending moments from attached piping and attached piping restrained free thermal expansion.

If you want someone to do the analysis for you, you will have to pay a consultant for that.
