Can a ladder backing plate be welded to the manhole reinforcement ring of an atmospheric pressure vessel?
If there is no specific prohibition, then it’s okay. :)
There’s no need for a gasket plate anymore; just weld the ladder support directly.
The manhole reinforcement ring is used to eliminate and reduce the stress concentration caused by openings in the cylinder. If you plan to add a ladder, it’s best to consult with the design firm. Such firms have experience and the necessary qualifications. To avoid potential problems and ensure safety, it’s important to follow the proper procedures. If something goes wrong and you don’t have any changes or approvals from the design firm, then you’ll have done good intentions but ended up making a mistake, and the safety authorities will come after you

You need to send a request to the design institute; they will tell you that this is an unexpected situation. Don’t send the request – you can proceed as usual; I’ll pretend I don’t know anything about it
Methanol and gasoline/diesel storage tanks are also pressure-free containers; you can try welding them on your own. Nothing will go wrong for now, but if an accident occurs, the responsibility will lie with you
