Hi
I am trying to analyze piping around storage tanks. And this is my first tankage analysis and I want to know how model settlement and how to solve it.
I need help.
Please give me some advice or article ...
Thank you very much.

Please search this forum with the word 'settlements'

Hi
I couldn't find anything good please help me

regards

Hi MNR

Collect settlement value from structure & feed it in tank anchor point with CNODE. If first support closer to tank affected with settlement put displacement with CNODE at that support also.

This settlement is likely to create problem in tank nozzle load.
You may consider following to pass nozzle load

1) Use spring support close to nozzle
2) Provide loop close to nozzle
3) Use expansion bellow at nozzle
4) Use hose at nozzle

Try to reed this post name:

"Rigid stiffness, tank modelling"
"Load case combinations (again)"

Hi
Thanks a lot guys.
but I want to use expansion joint and a gate valve connect to tank nozzle.
do I change the position of valve for expansion joint or not?
nozzle +expansion joint+valve
thanks in advance

You did not tell us the size of the tank, the size of the nozzle/pipe, the amount of the expected settlement or the time frame of the alleged settlement so it is a bit hard to offer real help.
However before I retired I had more than 45 years in the process plant engineering, design, field engineering and pipe fabrication. During that time I never saw or installed a tank connection with an expansion joint.

I would love to be able to show you how to do it with nothing but simple pipe configuration.
