Please give me some idea how to perform " DRY OUT " cases from TANK to Pump suction.

1. If we are using first support spring due to settlement , shall is it necesaary that for dry out case we have to use hanger load coming during operating load case . OR what is exact process ??


2. If wedo user defined/predefined hanger for DRY OUT case, then load come too high on Tank Nozzle

Where large tank fill / drain lines are concerned, the contents weight can be around five times the metal weight, so designing a spring for the filled case risks huge unbalanced loads when the pipe is drained.

Maybe a better solution would be avoid springs entirely. Use hard supports and a double-tied EXJ at the nozzle. This would take care of settlement and wall bulging too (provided it has two tie-rods).

Thanks Mr. MoverZ for your valuable suggestion.
