Hellow

I have only one year of experience in stress analysis and in Caesar II, and I have many doubts, I hope that my questions arenīt too stupid, please sorry...Iīll try to explain it

I have been trying to analyze a 20" diameter A106-B,in a termical plant,at 400šC and 0.2bar. The pipeline is inside a build and due to this condition there isnīt wind load case and there isnīt seismic load, because isnīt a seismic zone, and I havenīt ocassional loads.
I only have simple load W,P,T and D1 and D2 due to conected equipments desplacements to pipeline, and using CODE ASME B31.3:

L1: WW+HP (HYD)
L2: W+P1 (SUS)
L3: W+T1+P1+D1 (OPE)
L4: W+T1+P1+D2 (OPE)
L5: L3-L2 (T1+D1) (EXP)
L6: L4-L2 (T1+D2) (EXP)
L7: L3-L5 (EXP)
L8: L4-L6 (EXP)

Please this combination are correct?

Thank you four your help

Best regards
