Diesel Storage Tank Design

You have considerable latitude of choice in diameter versus length of the tank, so there may not be a one-size dimensional standard. However, other standards apply, such as required nozzles, internal baffles (especially in mobile tanks), double containment if integral to the tank, etc. Some agencies you would want to check might include: USDOT, API, NFPA, and UL in the US; others abroad.

This a larger topic than can be addressed fully in a brief forum post.

Thank you for the tips. Actually, lenght, diameter & thickness were all given already,\ which are 4000mm x 1800mm x 6 mm. I want to know if this data is correct for 10 cubic meter capacity? If it is correct, I need to know the standard saddle support and its location. Thanks.

If the heads were the same density as the as the material stored in the tank, the ideal supports would be placed at 25% and 75% along the length. In reality, the heads will be heavier, so approximately 20% and 80% is a reasonable choice. I don't know of an exact standard on it. Plate of 6mm should be good.

(1.788 m/2)² x π x 3.88 m ≈ 11.53 m³, so your tank capacity gives reserve even beyond 10 m³.

Thank you so much for the info. Regarding also with the saddle support, I want to know if 2 saddle supports is enough?

i think 6mm thickness is overdesign which i have not, but if there's humidity it's quiet enough, also the tank installation depend on, above ground or under ground, about the dimension, i think it depened on the steel sheets availablity dimension, off-cut that would be

If possible get hold of API650 - that will give you total guide-lines, calculations including inspection requirements for storage tanks.

The API validated tanks will be acceptable by all others. In case it is going to be your ongoing project (not a single time affair) then get a copy of it.

Also quite a few softwares (not free) are available for tank design to API650. You can search the net for them (that may be cheaper than the standard )

Also don't forget API2000 (Venting requirements of low pressure and atmospheric storage tanks) - refrigerated and non refrigerated.

- Hopefully proper software will tackle this also.

Since you are discussing tank supports, it is obviously above ground.

In this situation, there are two related issues to consider-

1- You should have a containment wall around the tank to capture full volume (plus some reserve) in case of a rupture. Use a sump with ejection pump for rain water captured.

2- You must ground the tank to avoid any static sparks that could cause problems.

Another item- Is it possible to mount the tank vertically rather than horizontally? This would allow just grouting the circular base on a relatively small pad rather than building support columns with radius top to suit the tank or bending and structurally supporting the saddles for the tank.
