How to find S_Cavg, S_Ravg and S_Rmin of Appendix 10 of ASME IID.

Part 10 of "API 579-1/ASME FFS-1 Fitness-For-Service". Use the project omega method.
I am able to precisely replicate the allowable stresses specified in ASME II Part D.

Thanks for your information but i am unable to co relate the clause 10B.2.1 MPC Project Omega of API 579-1.

Kindly provide some reference calculation for understanding.

Your reply is confusing.
Where is clause 10B.2.1? I am unable to find it.
What do you mean by being unable co relate?

Sorry for confusion, total 8 clause is there in the part 10 of API 579-1.
I am new to this API 579-1, How I will understand or how to start to finding the
SCavg, SRavg and SRmin value.

Use Step 1 to 13 in Section 10.5.2 for calculating SCavg.
Use Annex 10B for calculating SRavg and SRmin. API 530 is even better as it has examples and graghs for calculating SRavg and SRmin.

It took me a very long time to work out how to do the calculation, so I'm not inclined to hand over my calculations. Good luck.
