Shell nozzles

The pressure drop over the shell nozzles should be added to this value although this is usually only significant with gases. In general, the nozzle pressure loss is 1.5 velocity heads for the inlet and 0.5 velocity heads for the outlet, based on the nozzle area or the...

Angular connections can save one or two bends in the pipe line. These connections are more often applied to top shell nozzle or to the tube side. Excessive angular connection at the bottom can... 

Components Parts that make up a piece of equipment or equipment itan. For example, a pressure boundary may consist of components (pipe, elbows, heat exchanger tubes, heads, shells, nozzles, skirts, supports, etc.) that are bolted or welded and assembled to make up equipment items [10]. 

With an RTP shell, fit-up of the components of the vessel. This includes head to shell, nozzles to heads and shell, and shell joints. Alignment is more critical in a lined vessel than in an unlined one.
