Testing Above Ground Storage Tanks
Testing Above Ground Storage Tanks
(OP)
Does anyone know of a specific regulation that requires hydrostatic testing of large (>750,000 gal) field-erected above ground storage tanks?
Are other tests acceptable in place of hydrostatic testing? i.e radiographic testing
Are there different testing requirements for petroleum versus non-petroleum storage tanks?

RE: Testing Above Ground Storage Tanks
You do not mention code of construction.
If it is API 650 there are alternatives.
See API 650 Clause 5.3.5,

RE: Testing Above Ground Storage Tanks
The first place I would look is API650. "Hydrotesting" (filling the tank with water and waiting) is most commonly performed. However, testing welded joints with a vacuum box is also a permissable method if agreed to by the purchaser.
You did not mention your code of construction.
The local inspection authority may have important input here
RE: Testing Above Ground Storage Tanks
In addition to above posts by hydrotesting you are also applying weight to the tank base which essentially tests/loads the foundation. Would you/Client be happy that the first time the tank base is loaded is with the product being stored??
