Procedure 7-1 Stresses in Circular Rings

Z = section modulus, in. t = shell thickness, in. ffx = longitudinal stress, psi = circumferential stress, psi e = length of shell which acts with attachment, in. 

A = ASME external pressure factor As = metal cross-sectional area of shell, in.  

E = joint efficiency El = modulus of elasticity, psi p = allowable circumferential buckling stress, Ib/in. 

Longitudinal tension 1.5SE = Longitudinal compression Factor B = Circumferential compression 0.5Fy = Circumferential buckling p - Ib/in.
