Water storage Tank

[AlexRG]

Hi, im designing a water storage tank, can i use the API-650 to do all the calculations??

You would be better served to use the AWWA D100. The basic principles are the same as API 650, but the material design stresses listed in AWWA are lower than API. Also, if this tank is for fire protection, you need to refer to NFPA-22.

It depends on what it's for.

For municipal/ potable water, normally AWWA D100 would be used, and might be required.

If it's industrial, raw water, waste water, etc., API-650 could be used. Also check out Appendix A as an option.

If it's a small tank, there won't be any savings from using API-650.

API-650 has more details on typical nozzle construction, whereas AWWA D100 has more requirements on ladders and stuff.

Is the tank elevated or ground supported?

yes its a small tank, about 16" of diameter and 22" of height, the material to be used its A-36 carbon steel. Its a ground supported water storage tank.

Did you mean 16 FEET x 22 FEET? A 16 inch x 22 inch tank is truly a baby tank. Either way the design code would make little difference. I'd use AWWA D100 in this case. It a simpler Code than API-650. And, it is specifically for water service tanks.

ok thanks for your advice, and by the way, its 16 FEET x 22 FEET, sorry about that.

@AlexRG: guess you do well to recheck your units before foraying into design! All the best.
