Jacket Opening

Hello Everyone,
If Jacket O.D is 1000mm than as per Appendix:9-4(b) 100 mm opening is not acceptable??
i think i am missing something !!
please help
Thanks.

RE: Jacket Opening

"...the maximum size of opening need not exceed 2 in. (50 mm) pipe size (DN 50) for all diameter vessels". That is, 100 mm opening is not acceptable.
No, there is nothing added somewhere else in the code.
Cheers,
