# Question of procedure for Buried pipe evaluation with ASME B31.1 Nonmandatory Appendix VII

## Question of procedure for Buried pipe evaluation with ASME B31.1 Nonmandatory Appendix VII

(OP)

Dear sir,

One of my client asked me to calculate and verify buried pipe manually.
Referred relative codes are ASME B31.1 Nonmandatory Appendix VII and PVP2002-1271.

My questions are as follows;
1. Is that same result compare CAESAR II and Appendix VII?
Or First, calculate factors and apply factors to CAESAR II?
2. Can I make a result manually without using CAESAR II?
Suddenly Para. VII-6.5 mentions Computing calculation for Sc.
Is that means calculate manual and apply automatic?
3. If then, How can I input at CAESAR II?
What is procedure of analysis?
- Calculation Appendix VII
- Modelling as per Appendix VII such as element length
- Input factors ; spring rate, force, friction force
(at the restraint input box)
- Computer result check ; stress

I hope that you knows these matters,

If you can't make hand calculations that match Caesar, or v/v, at convincingly close accuracy, you should not be using Caesar.

HI LEECUP,

I AM CURIOUS DID YOU CROSS CHECK WITH YOUR HAND CALCULATION(ASME B31.1 Nonmandatory Appendix VII)WITH CAESAR 2 IS IT SAME.

THANKS.

Dear MEDIUMINCH.

I have done hand calculation already in accordance with ASME B31.1 Nonmandatory Appendix VII when I write a this thread.
But at that moment, I don't know how those results match.

Main question is
" Why Caesar II results are came up in para VII-6.5 Results of Analysis? "
