Hi everyone,

I have a model which includes underground piping. I'm using ASME B31.4 and it shows allowable operating stresses for all operating cases except the one with T2(w+T2+P1). I'm wondering why this is happening? is there something wrong with the model or just underground piping shouldn't have T2 temperature?

Thanks

There is nothing special about "T2". If you can't resolve the issue open a Support Request on Smart Support and send in the job for review.
