per 4.6.
5.7.6.1.b - Shell nozzles (and flanges, if specified by the Purchaser as an alternate to a. above) shall conform to
Figure 5.7b, Figure 5.8, and Figure 5.10 and Tables 5.6a through 5.8b, but other shapes are permitted by 5.7.1.8. An
alternative connection design is permissible for the nozzle end that is not welded to the shell, if it provides equivalent
strength, toughness, leak tightness, and utility and if the Purchaser agrees to its use in writing.
Thank you for your prompt reply. As i understanding from above statement, other standard flange are allow. please correct me if i am wrong.
But it is applicable to shell manholes as well ?

That is the reason our client insist on JIS stnadard flange instead of B16.5 flange for shell manhole.
The weight of JIS flange is much much more light than B16.5 flange.
