Dear shr,

I have never evaluated nozzel for WNC load case.Have you done so in any specific case?If so, please share your experience.

Dear Nikhil,

The most important use of WNC load case is for Nozzle Alingnment Check in case of Pump/Compressor/Turbine/Vessels

Following WNC cases are generally used in process and power piping.Moreover they are project specific and varies with projects and clients.

1)WNC+H (HANGER ACTIVE)This gives pipe and insulation weight considering hangers active on provided locations.

2)WNC+H (HANGER AS RIGID)This gives pipe and insulation weight considering rigid support at all hanger locations.

Pick highest values from above two cases.

3)W-WNC This gives process fluid weight

4)WW-WNC this gives water wight for hydrotesting

Informations from these load cases are used by Civil and Equipment(If pipe supported from equipment)for structure design.

I hope this will be of some use.

Regards,
Aslam
