Nozzle on Storage Tank Roof Weld
(OP)
Hi all,
Is it a problem to add a nozzle or a square opening on the weld line of a storage tank roof? I cannot see anything on that in API 650.
Thnx

It is such a large opening that can't avoid the weld line so we will go ahead with it and pay attention to the weld. Structurally it does not require a reinf. doubling plate, as load is not much. But would you insert one to have cleaner weld at the nozzle neck?

It sounds like you are putting in a square hinged manyway on an existing roof? I would add the reinforcement especially crossing a seam.

This is reason enough to include a reinforcing plate.

I always include a re-pad and let the owner say "take it off" rather than not show it an not give them the opportunity to make that decision for themselves. Most if not all accept the drawings as is.
