Loads on roof nozzles in a API 650 tank
Loads on roof nozzles in a API 650 tank
(OP)
Dear All,
I would like to know how can I calculate the maximum allowable load on a roof nozzle in a API 650 tank.
I have seen Appendix P in API 650 for calculating loads on shell openings, but I have not found anything for roof nozzles.
We have a tank (already built) and we want to install steam traps on roof nozzles. We need to know the maximum allowable load, depending on nozzle size, roof type, reinforcement...
Best Regards,

Shell calc's could used, if and only if your roof is built like a shell, with extra thickness and repads. Expensive. We just use pipe supports, and don't put pipe loads into roof nozz's.
