TStE = maximum allowable working pressure, psi
RFS
Where:
TS = ultimate tensile strength of shell plates, psi
t = minimum thickness of shell plate, in weakest course, in inches
E = efficiency of longitudinal joint:
For tube ligaments, E shall be determined by the rules given in Section I of the ASME Code. For riveted construction, refer to the National Board Inspection Code. For seamless construction, E shall be considered 100%.
R = inside radius of the weakest course of the shell, in inches FS = factor of safety permitted.
