Any idea what code would an vertical, above ground, 10' dia x 30' tall chrorine tank under 3 psi (liquid & vapor) be designed & inspected to?

Client has given few specs: 1/2" carbon plate, CJP welds except for weld at shell bottom, I-beam reinforced flat bottom & top.

Seems API 620 code has been suggested over VIII. I know RT is required. Hydro required or is there an alternative since this would be a large amount of water? Wouldn't want pneumatic test...

Thanks in advance for comments and advice...

Please refer to
Pamphlet 005: Bulk storage of liquid chlorine from The Chlorine Institute .

Also it may be a good idea to check with state Inspection & state EPA

Thank you!

Chlorine tanks are designed as pressure vessels .
Sec VIII Div 1 can be used - for example

Vessels are 100 % RT with PWHT (UW -2 ).

Boiling point of Chlorine at atmospheric pressure (zero gauge pressure) has to be considered as MDMT (UG 20).

Pressure of gas at ambient temperature is also to considered (UG 22).

Ofcourse all local regulations have to be followed.
