Factory-Coated Bolted Steel Tanks for Water Storage
|Publication Date:||25 January 2009|
The purpose of this standard is to provide minimum requirements for the design, construction, inspection, and testing of new cylindrical, factory-coated, bolted carbon steel tanks for the storage of water. This standard is only applicable to tanks with a base elevation substantially at ground level.
Tank roofs. All tanks storing potable water shall have roofs. Roofs may be column-supported, self-supported, or aluminum dome. Tanks storing nonpotable water may be constructed without roofs.
Items not described. This standard does not cover all details of design and construction. Details that are not addressed shall be designed and constructed to be as adequate and as safe as those that would otherwise be provided under this standard. This standard is not applicable to tanks of corrugated construction. This standard is not applicable to tanks constructed of stacked plates or sheets laminated to form multiple layers.
Local requirements. This standard is not intended to cover storage tanks erected in areas subject to regulations more stringent than the requirements contained within this standard. In such cases, this standard should be followed where it does not conflict with local requirements. Where more stringent local, municipal, county, or state government requirements apply, such requirements shall be specified, and this standard shall be interpreted to supplement them.
