Hello All,
I need your insight.
We are building a process tank that is designed to API650.
By process, I mean it is not a simple storage API 650 tank and there is many internal plates (kick plates, deflectors etc.) inside tank that are welded to shell for a its process requirements.
Some...

Thanks! You got that right!
For foundation settlement concern of the tank during hydro, the hydro procedure is asking to do full tank hydro first to the elevation of 12.5-m to ensure even settlement. Then one side chamber slowly drains to do the second phase of hydro for 10-m...
@LittleInch,
I understand your safety point, I am also of the firm opinion that chambers should be hydro tested separately to ensure the wall design and the wall/shell junction integrity and safety before tanks goes to operation.
Please note this is not a simple storage API tank, it is a...
HTURKAK,
The wall to shell junction on the shell is heavily reinforced for the same reason you raised, as well the wall itself is heavily reinforced, the design is checked/verified by FEA for safe operation at 10-m height level difference.
The question is should the design also be validated...
Thanks folks!
The dividing wall is hugely reinforced by stiffeners and properly seal welded to the shell that is also locally reinforced to the shell/wall junction because of 10-m water level difference (wall design and junction was verified by FEA). This is not a storage tank, we have a...
The tank has not collapsed, we want to do hydro test brand new tank now, and we were wondering if we need to hydro test each internal chamber separately (in addition to API 650 that requires full tank cylinder to be tested) to ensure the interface wall design is safe.
Here is the sketch, the wall splitting chamber 1 and 2 is designed for 10-m water level difference and is 10-m High too. Does Chamber 1 or 2 need to be separately hydrotested for the same 10-m high to ensure strength safety of the wall in between? The 10-m water level difference requirement for...
Hi Folks,
We are in process of hydro testing an API 650 tank, cylindrical design, 12.5-m H x 39-m DIA.
The tank has multiple chambers that are isolated from each other, imagine now one big wall of 10-m Height separating the tank into two compartments.
The isolating wall is designed for...
