API 650 Welded Steel Tanks for Oil Storage - 2005

API 650 Standard for Welded Steel Tanks for Oil Storage covers material, design, fabrication, erection, and testing requirements for aboveground, vertical, cylindrical, closed- and open-top, welded steel storage tanks in various sizes and capacities. Applies to tanks with internal pressures approximating atmospheric pressure, but higher pressure is permitted when additional requirements are met. This standard applies only to tanks whose entire bottoms are uniformly supported and in nonrefrigerated service with a maximum operating temperature of 90°C (200°F). (Purchase includes addenda to the current edition of the standard.) (API650, API 650, API-650, 650API).

API 650-2009 Welded Tanks for Oil Storage - ir_71 - 01-13-2011

API 650-2009 Welded Tanks for Oil Storage

1.1 GENERAL
1.1.1 This Standard establishes minimum requirements for material, design, fabrication, erection, and testing for vertical,
cylindrical, aboveground, closed- and open-top, welded storage tanks in various sizes and capacities for internal pressures
approximating atmospheric pressure (internal pressures not exceeding the weight of the roof plates), but a higher internal pressure
is permitted when additional requirements are met (see 1.1.12). This Standard applies only to tanks whose entire bottom is uniformly
supported and to tanks in non-refrigerated service that have a maximum design temperature of 93°C (200°F) or less (see
1.1.19).
1.1.2 This Standard is designed to provide industry with tanks of adequate safety and reasonable economy for use in the storage of
petroleum, petroleum products, and other liquid products. This Standard does not present or establish a fixed series of allowable tank
sizes; instead, it is intended to permit the Purchaser to select whatever size tank may best meet his needs. This Standard is intended to
help Purchasers and Manufacturers in ordering, fabricating, and erecting tanks; it is not intended to prohibit Purchasers and Manufacturers
from purchasing or fabricating tanks that meet specifications other than those contained in this Standard.
Note: A bullet (•) at the beginning of a paragraph indicates that there is an expressed decision or action required of the Purchaser. The Purchaser’s
responsibility is not limited to these decisions or actions alone. When such decisions and actions are taken, they are to be specified in
documents such as requisitions, change orders, data sheets, and drawings.
1.1.3 This Standard has requirements given in two alternate systems of units. The Manufacturer shall comply with either:
1. all of the requirements given in this Standard in SI units, or
2. all of the requirements given in this Standard in US Customary units.
The selection of which set of requirements (SI or US Customary) to apply shall be a matter of mutual agreement between the
Manufacturer and Purchaser and indicated on the Data Sheet, Page 1.
1.1.4 All tanks and appurtenances shall comply with the Data Sheet and all attachments.
1.1.5 Field-erected tanks shall be furnished completely erected, tested, and ready for service connections, unless specified otherwise.
Shop-fabricated tanks shall be furnished tested and ready for installation.
1.1.6 The appendices of this Standard provide a number of design options requiring decisions by the Purchaser, standard
requirements, recommendations, and information that supplements the basic standard. Except for Appendix L, an appendix
becomes a requirement only when the Purchaser specifies an option covered by that appendix or specifies the entire appendix. See
Table 1-1 for the status of each appendix.
1.1.7 Appendix A provides alternative simplified design requirements for tanks where the stressed components, such as shell
plates and reinforcing plates, are limited to a maximum nominal thickness of 12.5 mm (1/2 in.), including any corrosion allowance,
and whose design metal temperature exceeds the minimums stated in the appendix.
1.1.8 Appendix B provides recommendations for the design and construction of foundations for flat-bottom oil storage tanks.
1.1.9 Appendix C provides minimum requirements for pontoon-type and double-deck-type external floating roofs.
1.1.10 Appendix D provides requirements for submission of technical inquiries regarding this Standard.
1.1.11 Appendix E provides minimum requirements for tanks subject to seismic loading. An alternative or supplemental design
may be mutually agreed upon by the Manufacturer and the Purchaser.
1.1.12 Appendix F provides requirements for the design of tanks subject to a small internal pressure.
1.1.13 Appendix G provides requirements for aluminum dome roofs.
1.1.14 Appendix H provides minimum requirements that apply to an internal floating roof in a tank with a fixed roof at the top
of the tank shell.
1.1.15 Appendix I provides acceptable construction details that may be specified by the Purchaser for design and construction
of tank and foundation systems that provide leak detection and subgrade protection in the event of tank bottom leakage, and provides
for tanks supported by grillage.
1.1.16 Appendix J provides requirements covering the complete shop assembly of tanks that do not exceed 6 m (20 ft) in diameter.
1.1.17 Appendix K provides a sample application of the variable-design-point method to determine shell-plate thicknesses.
1.1.18 Appendix L provides the Data Sheet and the Data Sheet instructions for listing required information to be used by the
Purchaser and the Manufacturer. The use of the Data Sheet is mandatory, unless waived by the Purchaser.
1.1.19 Appendix M provides requirements for tanks with a maximum design temperature exceeding 93°C (200°F) but not
exceeding 260°C (500°F).
1.1.20 Appendix N provides requirements for the use of new or unused plate and pipe materials that are not completely identified
as complying with any listed specification for use in accordance with this Standard.
1.1.21 Appendix O provides recommendations for the design and construction of under-bottom connections for storage tanks.
1.1.22 Appendix P provides requirements for design of shell openings that conform to Tables 5-6a and 5-6b that are subject to
external piping loads. An alternative or supplemental design may be agreed upon by the Purchaser or Manufacturer.
1.1.23 Appendix R provides a description of the load combinations used for the design equations appearing in this Standard.
1.1.24 Appendix S provides requirements for stainless steel tanks.
1.1.25 Appendix SC provides requirements for mixed material tanks using stainless steel (including austenitic and duplex)
and carbon steel in the same tank for shell rings, bottom plates, roof structure, and other parts of a tank requiring high corrosion
resistance.
1.1.26 Appendix T summarizes the requirements for inspection by method of examination and the reference sections within the
Standard. The acceptance standards, inspector qualifications, and procedure requirements are also provided. This appendix is not
intended to be used alone to determine the inspection requirements within this Standard. The specific requirements listed within
each applicable section shall be followed in all cases.
1.1.27 Appendix U provides requirements covering the substitution of ultrasonic examination in lieu of radiographic examination.
1.1.28 Appendix V provides additional requirements for tanks that are designed to operate under external pressure (vacuum)
conditions.
1.1.29 Appendix W provides recommendations covering commercial and documentation issues. Alternative or supplemental
requirements may be mutually agreed upon by the Manufacturer and the Purchaser.
1.1.30 Appendix X provides requirements for duplex stainless steel tanks.
1.1.31 Appendix AL provides requirements for aluminum tanks.

RE: API 650 Welded Tanks for Oil Storage - mmireles - 03-07-2012

Sorry, but somebody was the API-650-Add3 complete, with all the pages. For example, in this documento don't exist la setion 7.5.5 Foundations (in the 7.5 Dimensional Tolerances).
Please, contact me: [email protected]
Thanks a lot.

RE: API 650 Welded Tanks for Oil Storage - fbx_rdnk - 03-07-2012

mmireles,

Addenda 3 is only a page replacement to the previous documents above. You need to download API 650-2009 with Addenda 2 from one of the above links, then change the pages as listed in Addenda 3. Sorry, it is not a completely new document; only page changes.

Note: Addenda 3 did not change Section 7.5 from what was listed in the primary document.

Regards

Dear all,

Im confused about all this versions... can someone have the time to make a single file with everything (all the changes), because i want to get this but im confused about all this versions.

Or is that easy like fbx_rdnk says.

Regards,
