Hello All,

Currently I am doing stress analysis of Metering System.
All stresses are within limits with Liberal ON but restraint load at node 42 ( Refer attached CAESAR II file)is around 23476 PSI in Opearting case no.8 (W+T1+P1+U1)

I dont have feeling how high force( magnitude) we can permit going to the restraint. I would appriciate your valuable input on this. ............First Question

Also process data for this project is :

Design Temp (MAX) = 200 deg.F
Design Temp (MIN) = -20 deg.F
Operating Temp (MAX) = 120 deg.F
Operating Temp (MIN) = 80 deg.F

My second question is what temperature difference should I consider for thermal analysis. Is it mandatory to use Design temperature (and not the maximum operating temp)for analysis?

Anant
