From API 2000 2.3.5.2 Pressure Transfer Blowoff, it states that if you may pressurize a vessel, tank truck, or railcar to move fluid to the storage tank.
So I get it, if you have that source vessel filled with lets say nitrogen your going to get a surge once the fluid has transfered into the storage vessel.
However, I'm working on a case where we have a manifold which will be blown down. The line needs to be blown down from the manifold since the pipe has a fairly long run from the building to the storage tank in the tank farm.
My question is, should we expect a similiar surge once the fluids blown down? Or should the pressure change be 'more stable'.
I'm leaning to the side that we will not see a surge because the pipe diameter does not change significantly.
