While API 650 says you should not do this, it also provides rules for where there is no other feasible option.

aoliveratapia,
You should review paragraph 5.7.3.4 of API 650, along with figures 5.6 and 5.9.
This problem is more common in small tanks, such as those covered by Annex J: Shop-Assembled Tanks, when they have multiple nozzles. If this is the case and your contract or client allows it, you could request to apply Annex J and apply what is indicated in paragraph J.3.6.4, which removes the radiography requirements indicated in 5.7.3.4.
