Optional UCS-66.1 Reductions (ASME B&PV Code, S. VIII)
Optional UCS-66.1 Reductions (ASME B&PV Code, S. VIII)
(OP)
I'm using some software that has an option box to "take Fig. UCS-66.1 reduction" in calculating minimum design metal temperature. Right offhand, I can't think why you wouldn't take that reduction all the time. But in that case, why would it be optional in the software? Am I overlooking some instance when that reduction should not be used?

Customer specs may restrict this reduction, and additionaly, for a program I use often (shall remain nameless) I don't trust it.
When I do take the reduction I get out my Code book and do it myself. If there is another way, I won't normally take the reduction.

A similar situation exists with Figure 323.2.2(b) in ASME B31.3. By the time you are in a position to satisfy the footnotes to be used in conjunction with the chart, you pretty much should already have done your flexibility analysis, which typically puts you at a stage in the design that is a bit too far down the road to start deciding if you can be A106 or A333.
