Permissible Bore in B16.47 Blind Flange
Permissible Bore in B16.47 Blind Flange
(OP)
Hello,
This question is with regards to the reinforcement calculation requirements when using a B16.47 blind flange with a centrally located nozzle.
For B16.5 blind flanges, using interpretation VIII-1-01-105, reinforcement calculations are not required as long as the opening is no larger than that listed in B16.5 Table 6.
I have taken a look through B16.47, but couldn't find an equivalent table. Is there any similar exemption size available for B16.47 flanges?
Thanks,
Marty

That was my fall-back approach. I was just wondering if I could get by without having to do an App 2 calc.
Thanks!
