ATM tank design-Corrosives
(OP)
Hi I am looking at finding a standard that could be used for design of an atmospheric process vessel (tank) for SG>1 toxic/corrosive products. The vessel diameter is 3m or less and will be supported on four legs.

And what is the product?
In the US, the tank would typically be specified with references to API-650 or API-620 "as applicable". Neither standard specifically covers leg-supported tanks. Neither addresses the specific requirements for corrosion with various products.
AWWA D100 covers leg supported tanks, that is, water towers. But it covers the design of legs and accompanying stresses in the shell in a very vague fashion that is of no help in the design process.
We used to have a standard that dealt specifically with sulfuric acid tanks, but I don't recall who put it out. It addressed mainly corrosion issues, as I recall, not structural details.

I think it is a drastic statement to say that legs are usually limited to 1m diameter tanks. I just finished a 4m diamter x 50 m tall tank on legs. It was an EN 13445 designed pressure vessel. Legs were needed for access and a skirt would not have had enough room to move around the equipment in the bottom. The legs were relatively tall, about 4m to 5m and x-braced.
lls,
You need to tell us more about the tank, height for example. Being in NZ, I expect you will have large seismic loads. I've done work at the Kinleith mill and seismic was a big issue.
