Dear Mathew,

You are absolutelly correct with your observation.This is the way nozzle is evaluted for any equipment and piping for any support arrangement.

The original question was asked like below

"When we have to consider the WNC load case. Is there any specific considerations to use this load case.

If we consider the WNC case do we need to activate the cold loads for spring hangers. "

I advised valid and genune reasons to consider WNC load case at the same time I was surprised to know that some respected member are relating it only with nozzle loads which is unheared off.

I guess dear habib is missing something while sizing his spring near his equipment nozzle.

For further discussion.

Regards,
Aslam
