stamp Vessel without UG-46 (f)
(OP)
We are fabricating a stamp Vessel (ASME Sec VIII Div 1) with dia 1000 mm, which do not have any Manway only one handhole of 14'' (as per client datasheet).
Since above conditions are not fullfilling UG-46 (f) (3) our inspector is not ready to register under asme,and our client
recommended to use project spec or data sheet first and if not clear then use codes.
Any suggetions are welcomed.

It is strange for your client to specify a 14" hand hole in lieu of 16" manhole to meet code requirement. I typically see a 8" or 10" handhole.

I think you can bypass mandatory manhole of UG-46(f)(3)when manhole were not impracticeable. Since, in the current case, mandatory manhole was not impracticeable because 14 inch could have been 16 inch easily.

Sorry there was a little mistake in my above post.

I am of the view, since 16 inch manhole was not impracticeable so UG-46(f)(3) could have been complied with easily. You can go to UG-46(f)(7) only when 16 inch manhole was really impracticeable.
Please add further.
