Maximum Nozzle Projection Length? 1

[DCCMech]

I've been asked to design a new nozzle off a sump on an existing vessel designed to ASME SectionVIII Div 1. The oddity of this is the projection that I've been asked for the nozzle to avoid other equipment in the area when bolting up the flange.

A 52" projection still passes WRC-107 criteria and a rough FEA even supporting the valve that will be bolted to the flange, so I'm confident in the design. My only concern is that I'm not familiar with code in respect to maximum projection lengths, I've only ever been concerned with what's happening on the nozzle/shell interface. Anyone familiar with such a projection limit in the current code?

There's no limit in the code for projection length, it is just a pipe added onto nozzle neck. You only need to check whether the weight of the pipe and of connected equipment requires a support to not overstress the nozzle.
