Nozzle Orientation of Shell and Tube Heat Exchangers

Nozzle orientation and location can affect the piping configurations at most exchanger arrangements.

A decision by the piping engineer to relocated the exchanger nozzles can often produce a neat and cost effective arrangement.

Although the piping designer does not have the freedom to independently relocate exchanger nozzles, suggested alternate nozzle locations can be made to exchanger engineer in the interest of improving external piping arrangements

– For example, an alternative B in following figure highlights an improved arrangement by relocating exchanger nozzles.

Following figure shows allowable nozzle configurations. Elbow or gooseneck nozzles are especially useful in reducing the height of large stacked exchangers.

Following figure shows the effects of using elbow nozzles on stacked
exchangers.
