Urea Storage Tank Material

[Doiscond]

I have been trying to determine what storage/transfer material options exist for 40% urea, kept at ambient/atmospheric conditions. There is a wealth of information online relating to materials needed for the high temperature/pressure production of urea, but I have not found much else for lesser conditions. I wouldn't want to spec a higher grade and more expensive material if it's not needed.

If anyone has any sources of information or verification of an existing system operating without issue that would be very helpful.

Thanks!

How large of a tank are we talking?
What are the purity requirements?
What will be your temperature control?

Still in the estimate phase of the project, but plan so far is a roughly 12k gallon tank for an industrial grade application. Temp control is dependent on material, if it's a steel tank then we'd have a half pipe jacket to keep it from salting out when the temp outside drops.
