Problem:
What code should I select WRC-107, WRC297, WRC-537?
Solution:
Due to liability lawsuits Bentley can not provide design details such as this. Recommend to review both codes and determine which is more applicable to your project.
Only comment is a quote from WRC-297:
WRC Bulletin 107, "Local Stresses in Spherical and Cylindrical Shells Due to External Loadings," by K. R. Wichman, A. G. Hopper, and J. L. Mershon, has been widely used by design analysts since its initial publication in August 1965. ........ The persistence of this need was a major motivating factor for preparation of this "Supplement" provided here in Bulletin 297 that broadens the coverage of Bulletin 107.
WRC Code limitations:
WRC107 WRC297
d/D <= 0.33 (1) d/D <= 0.5
D/T <= 600 20 <= D/T <= 2500
Where
d - outside dia. of the nozzle
D - outside dia. of the shell
T - shell wall thickness
Approximate limit of WRC107 for spherical shells is d /D = 0.33
(1) - Subsequent revisions have conservatively extended d/D <= 0.5 (but man be inaccuracies)
