RE: API Piping Design Formula
There are many design examples on the web.
RE: API Piping Design Formula
By the way, S (Allwoable STress Value) must be selected as 0.8 X Minimum Yield strength or only Minimum Yield strength . please refer me to the clause of the code.
tnx
RE: API Piping Design Formula
Allowable stress is as tabulated for the listed approved materials. It is NOT = 0.8 * SMYS

RE: API Piping Design Formula
You are confusing lacation safety factor F with API design factor. Under the alterantive rules provisions of Part 192 F may = 0.80 maximum. Use ASME B31.8 for design if gas. It must be understood that when one designs with F = .80, additional testing and inspections of pipe, pipe line welding and the pipeline during service are mandated.
