Vessel and Tank deformation for pipe stress analysis
Vessel and Tank deformation for pipe stress analysis
(OP)
Hi all,
I am doing some pipe stress analysis and I wanna considerer the deformation in the anchor point under the thermal load.
There is any way to estimate thermal deformation in the nozzle for steel storage tanks and vessel?
Thanks in advance

It's a bit of a vague question so a bit of a vague answer. If you have a more specific question then add more details.

If the pipe is connected to the top of the tank, that will be the anchor point, but under thermal conditions the tank will expland and flange will move.
This movement is what I am asking for...

Horizontal Displacement = Tank temperature at nozzle height X linear thermal expansion coefficient X Radius to face of nozzle.
you must get smarter than the software you're using.

1. Rotation due to bulge, worst in the lower courses.
2. The effects of settlement and ground compression under filling / emptying.
These may be quite significant problem areas dependent upon the tank size.
Also, defining a tank nozzle as an anchor ... i.e., rotationally fixed would be very conservative, since there will actually be significant flexibility. This can be addressed using data from API 650.
IMHO, the best solution to most large tank connections at a low elevation is a double-tied bellows at the nozzle.
