Recommended Nozzle Loads
Recommended Nozzle Loads
(OP)
A question that has probably been asked several times but I was unable to find a straight answer - Where is a good place to find recommended nozzle loads (forces and moments) for process equipment for use in a WRC-107 analysis?

However, fegenbush advice is safer, to get the piping stresses from piping stress analysis.

Take a look at ASME's DC website for more potential papers.

Really it's a set of forces and moments for a given nozzle that are realistic and which may be used with confidence by both the equipment designer and the piping stress engineer, whilst doing their work in parallel. Conventionally an accepted set of data is used as a max by the piper and min by the equipment designer.
It is not usually feasible to complete a vessel design prior to starting a piping stress analysis or vice versa.
To suggest zero allowable equipment loads means .... don't connect any pipe to it, perhaps park it in a field.
There are perfectly reasonable sources of allowable nozzle load sets such as NEMA SM-23, API 610, API 650, API 661 etc. The only grey area is vessel and exchanger nozzle loads. These are addressed in an easily usable form in NORSOK R-001 section 5.1.5, available on the web, free of charge.

Cranky older engineer response (caution..!!)
