Dear Richard,

I'm doing Stress Analysis for Pipeline with Code ASME B31.4 and ASME B31.8.

Would like to ask, What it means "Fully Corroded Condition" as "check" on configuration settings.

I've tried input as Thickness, Corrosion Allowance, and Fully Corroded (on configuration setting) as check.

Second input, I've put, actual WT minus CA itself, and put 0 mm on CA place, and left "Fully Corroded" as un-check.

I'm quite confused that result is different.

My intention is that,
to find out the stress result on all case (Sustained, Expansion, etc.) when Pipeline have already corroded, let's say after 20 years.

Would you please advice on this matter?
