Hi Mahdi

As far as i understandand that tank settlement will change in vertical distance (in case of nozzle located at elevated position) or vertical clearance in grade level piping. In both cases you can handle this situation by providing screw type adjustable support. In this support you can adjust the TOS (top of support) as per BOP results in settlement of the tank.

Hi all
In the LAVAN LPG project we have some LPG tanks. After hydro test according to soil reports we have 1 to 2.5 cm settlement and time of this test is 3 months. So according to project conditions we have we don't have enough time. And we have to change the piping routes. So here I need to help.
What can I do?
We want to not buy expansion joint or loose flange can we use CAN support (negative springs) or not?
If we have to use expansion joint do we have special standard about this one or not?

Please help me.
Thanks advanced.
Mahdi.N.R
