Dear all,
I'm facing a problem regarding support design for a system:
The system is a 3" 6.5 barg Nitrogen blanketing line connecting to the top of (To the roof) a 15 meter diameter tank. It also contais a PCV (NOT PSV!) and a bypass line aswell.
As I modelled the system, I think there is no need for any semianchor for the line because it is connected to the tank nozzel which is quiet rigid. Also there shouldn'e be a high load during the PCV operation. The tank nozzel load is acceptable now, but I'm having arguments with my coalligues regarding some sort of stop or semianchor before the PCV to prevent occasional loads. I think it's not necessary, let me know your ideas.
Best
