F= .5, 90 degree plane 1

[engineer54]

can you claim the nozzle drop in the 90 degree plane with nozzle in cylindrical shell? inside projection h= nozzle drop for
square cut nozzle.

 

[SnTMan]

engineer54, by "claim the nozzle drop" I assume you mean take credit for inside projection, A3?

Yes, subject to limits of reinforcemet, see UG-40, and subjecct to applicability of reduced F factor, see definition of "F" in UG-37. Note your opening detail must be considered as integrally reinforced, see UW-16(c). Note the total drop may exceed the allowable limits.

Regards,

Mike

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

 

[engineer54]

What I mean by nozzle drop is : Looking at the 90 deg plane, the distance measured from the top centerline of the nozzle to the corner of the square cut nozzle.
Thanks

You should also read Interpretation VIII-1-13-12. I think it addresses your question, and provides a strong argument for you if you need to justify your approach. This Interpretation is available in the tail end of the 2015 edition of Div. 1 as downloaded from IHS.
