RE: Design Factor for Pipeline Anchor Flange
A. If there is not a big cost difference then use the worst case.
B. If there is a big cost difference, then present your figures to your Client and see if they want to be realistic (cheaper) or conservative (more expensive).
prognosis: Lead or Lag
RE: Design Factor for Pipeline Anchor Flange
In such case, I don't know if any design factor would need to apply.
RE: Design Factor for Pipeline Anchor Flange
You should use the design factor specified by your design code, 0.72 if it is B31.4, or that specified by your class location, if it is B31.8, probably 0.60, 0.50, or maybe 0.40 if it's in a large city location.
