Is there a limitation on the size for a tank with a fixed roof that does not have a floating roof.

I refer to API 650.

RE: Is there a limitation on the size for a tank with a fixed roof that does not have a floating roof.

API-650 doesn't have a limitation. Local fire codes and state/federal emissions rules may have limitations, depending on what the product is.

This tank will be an intermix tank 45m³ . Product can be a mixture of Unleaded petrol , Diesel, Jet Fuel and Crude Oil.

RE: Is there a limitation on the size for a tank with a fixed roof that does not have a floating roof.

Why would that be an API 650 tank, when you can make it a horizontal double skin tank, self bunded and safe. Also, a lot cheaper than any vertical API 650 tank. Save also an bunding requirements.
Think of that,

gr2...

When you say "horizontal", I assume you mean horizontal axis... correct ?

How do you support a "horizontal double skin tank" ? Saddles ? Or what ?

Can you give us some examples ? Drawings ??? Pictures ?

The only "double skinned" tanks I have seen have been vertical axis....

RE: Is there a limitation on the size for a tank with a fixed roof that does not have a floating roof.

MJCronin,

Saddles or rails can support a horizontal tank. I would assume that gr2vessels is talking something akin to a UL 142 tank which can be quite common to store petroleum products.

RE: Is there a limitation on the size for a tank with a fixed roof that does not have a floating roof.

Yes, fegenbush, you are correct;- there are in Oz standards for storing flammable liquids, including diesel fuel, petrol (gas), E85, ethanol/methanol, etc in size of 30 -60 kl and larger. UL 142 is complementing AS 1692 and AS 1940. There are also the 'square cubes' designed double skin to AS 1692, removable storage tanks for fuel, fitted with lifting lugs or other features to make them transportable. They all share the self bunding feature, making them transportable. They are commonly used on large scale industrial sites for refuelling facilities, fitted with safe fuel loading/unloading connections for truck filling operations, for fuel distribution to operating machinery. The horizontal, cylindrical large storage tanks for ethanol storage on large food processing sites are seated on two support saddles and fitted with all the safety features per UL 142 and correspondent AS standards. The best part is more than significant cost reduction compared with API 650 tanks. Two only saddles to support a 50,000 litre ethanol tank!
