caustic soda 30% tank 1

[jbdamian]

Anybody there who can help me decide on material of storage tank which will be used to store caustic soda 30% and shall be stored outside under direct sunlight. SS304, PVC and mild steel with corrosion coating i.e epoxy lining, nickel, as par as I know can be used for these. Am I right? By the way we will store about 29 tons of caustic soda. Thanks for any advice.

In general, I would disqualify PVC because it is not robust like steel or SS. Specifically, I would disqualify PVC for a direct sunlight application.

Did you mean GRP (glass reinforced polymer)?

Good luck,
Latexman

Have you read faq124-1096

I too would eliminate PVC -- too brittle. The least expensive practical solution would be a crosslinked polyethylene tank. Choose the heavy wall construction for liquids up to SG = 1.9. Also available double walled for containment requirements.
