ASME Sec.8 Vs ASME B31.3

[Metallurgistrbi]

Hello all,

I was just wondering if anyone can explain the following discrepancy

API 5L X52 (not normalized) pipe classified as Category A in ASME B31.3 and if normalized falls under category B. Refer Figure 323.2.2A Note 3 & Table A-1
Same Pipe are generally classified as category B in ASME Sec.8 div.1 and if normalized falls under category C. Refer Figure UCS-66M note 2c and 3 b.

How come the same material can have different impact requirements when both the code are dealing with pressure containing components.

Thanks for all of your valuable input

API 5L is not included in ASME VIII Div 1.
