Tank V-301 is designed with lateral nozzles same size to have a bigger flexibility in the field. It means to have the possibility to change the inlet of the lines for any problem can arise at site (i.e. erection, supporting, routing) without any modification to the V-301. The P&ID n. A030P001, shows the size of the nozzles based on the size of the inlet line. This will be revised indicating the necessary reductions as shown in the piping arrangement drawing.
