The additional consideration in Eq. (3b) of ASME B31.3 is the addition of the allowances (internal corrosion increases the inside diameter in the corroded condition). With this additional consideration, Eq. (3b) of ASME B31.3 based on inside diameter provides the same required thickness as Eq. (3a) based on outside diameter.

The ASME B31.3 Code defines unlisted components as components not in Tables 326.1, A326.1, or K326.1. Unlisted components can have pressure ratings but the owner and/or the designer has the responsibility to verify that the design, materials, fabrication, examination, and testing of the component meet the requirements of ASME B31.3.
