Manhole cover material
Manhole cover material
(OP)
Dear All,
I'm designing a special Manway for coded Vessel ( ASME Section VIII Div.1), my question is very simple : Can I use plate (SA-240-304 for example), for this attached manhole cover, which is fabricated from one machined piece, or it's mandatory to use only forged material?
Thanks.
Regards.

The problem with sloppy work is that the supply FAR EXCEEDS the demand

À response to Don56, no proof test is expected, i calculate the MAWP,
I Know that habitually the blind or cover flange is made from plate, but is it still true with this special shape,
And by the way the raison for this shape is requirement of sanitary application .
Thanks.
Regards
