Baffle plate thickness for a rectangle tank
Baffle plate thickness for a rectangle tank
(OP)
PLEASE HELP Kindly help. There is metallic rectangular tank, where liquid is stored. (On any one half). There is a plate (baffle plate) which divides the tank into two. The baffle plate and the tank assembly is in a civil pit. Baffle plate is welded on both sides on insert plates of the civil pit and baffle plate is not supported at the bottom.
Hence the weight of the tank of 6 tons and additional load of liquid in any one half which is 7.8 ( total 13.8 tons) is acting on baffle plate. That means baffle plate is acting as a beam fixed at both sides,
And a load is acting from 1350 mm from one edge to 3300 mm and again there is a gap of 1350 mm till the another fixed end.
| 1350 | 3300 | 1350 |

x m n y
Consider Liquid is present only in one section say Section A marked on the sketch which
1.1X 3.3x 1.8 = 6.534 cum
Weight is 6.534 X 1.2 (density) = 7.8 tons (max)
Box weight is 3.5 tons. (Approximately as given by vendor)
Now the baffle plate is fixed at point X and Point Y , Point M and N are the places where weight of the box and the liquid act on Baffle plate. Baffle plate is welded at x and Y but not rested on floor
Therefore Baffle plate 6 meter length ( x and y) ( 1.8 meter height and about 6 mm thk) is considered a fixed or simply supported beam
Do u think the thickness 6 mm sufficient?
How to actually see buckling case?
How to check for compression case?
Can you kindly help me with calculations please.

By "tons", I take it tonnes is meant.
The "box weight" is 3.5 tonnes, but the "tank weight" is 6 tonnes. Is that because you have factored the vendor's load?
Sounds like you will need a horizontally spanning member top and bottom to resist the couple created by the unbalanced load in the tank.

I am sorry I could not able to upload the sketch. Civil person, Tank is 2200 Width, 3300 Length, 1800 height
Baffle which devides the tank into two half of 1100 each
baffle plate lenth is 6000 and 1800 height
so baffle extends over tank wall by 1350 both sides
( 6000- 3300 = 2700 and 2700/2 = 1350
But baffle plate is fixed at the ends X and Y but not supported .
all dimensions in mm and box and tank are same . Yes it is for sulphur. Liquid weight + tank weight is 7.8 tonnes
