Hello Fai Maz,

The surge pressure is really that 9.14 barg. Actually I have already the surge analysis report from the process group. They have 7 cases of ESD of control valves. I chose the case that would give me a conservative result, and that case registered a peak surge pressure of 9.14 barg.

Statically, the force that would be expected at each nodes, is around 600kn for my case, assuming of course that the pressure rise time is zero. But the process had given me a rise time of 15 seconds after ESD. So I run a dynamic analysis, and get a low loads on my supports. I'm just not sure if this is a right procedure.
