Am running an analysis for a new line which will connect to older lines and existing/new equipment (tank and heat exchangers). Although the manual I have discusses evaluation by CII of nozzle loading in accordance with HEI, I cannot find this option on the nozzle screen. Perhaps it's a version issue. Are there general guidelines for maximum allowable loads at a heat exchanger nozzle imposed by the piping system? If things are the same as I remember them (haven't done this work for +10 years), I would expect the vendors to say either their equipment is so strong that the pipe would fail first, or that the allowable loads are zero, either of which is no help at all.
