Jan 15,2007 API 650 tanks shell to bottom welds#0183;API 650 Section 3.10.2.5 (Note the word shall).The roof is designed to fail vs.the shell failing.ie-the roof blows off vs.the tank blows out.Was the tank constructed based on API 650 Appendix F? Even that does not allow backewlding the roof plates to the compression bar or top angle.See API 650 Appendix F.3,Figure F-2.Welding sequence for API Tank bottom - AST ForumDec 10,2009 API 650 tanks shell to bottom welds#0183;Welding sequence for API Tank bottom. The main thing to keep in mind is to have almost all the shell to bottom corner weld completed beforehand.Most everyone welds all the short seams prior to welding the long seams and leave the outer periphery of seams open until last.I personally had better luck in keeping the bottom reasonably flat by V750 Vacuum Box for Weld Inspection EddyfiThe V750 vacuum box has been designed for the operators and to API 650/653 recommendations.Bubble leak (or vacuum box) testing is an integral part of tank inspections as required by the American Petroleum Institute (API) and other international standards associations to establish the condition of tank bottom plate welds and shell-to-bottom plate welds.

of a tank inspection process as recommended by API and other international standards to establish the condition of a tank bottom plate weld or shell to bottom plate weld.The latest edition to Silverwings vacuum box range is the V750 which has been completely redesigned with the operator and API 650 / 653 inspection standards in mind.Technical Inquiries for API Standard 650,Welded TanksIs it permissible to use Group I plates for a tank bottom,except for plates welded to the shell,for tanks with a -50 API 650 tanks shell to bottom welds#176;F design metal temperature? API 650 only addresses toughness of bottom plates welded to the shell,per Section 2.2.9 or 2.2.10.2.2.9 Table 2-3 9th - May 1993 Does Table 2-3 only relate to plates that are to be heat-treated Tank Shell Repair Advance Tank ConstructionIf the existing plate thicknesses meet API 650 or AWWA D100 standards,we will separate the roof from the shell,insert the new shell ring,extend all columns and then reattach the existing roof.In other situations,we will add a thicker ring at the bottom of the tank,then perform modifications to get the required soil bearing.

Readers can refer to Annex BEvaluation of Tank Bottom Settlement of API Standard 653 for assessing tank settlements.As specified in this standard,a tank shell needs to be evaluated based on the deformation of the shell as well as out-of-plane settlement (circumferential settlement) of tank bottom.The bottom plate is also required to be TECHNIQUES METHODOLOGIES FOR TANK BOTTOMtank shell,the bottom (annular) plate is subjected to severe reversible stress near the welded storage tanks or API 650 welded steel tanks for oil storage.(Items not covered under IS 803 as per API 650) (b) API 653,Tank inspection,repair,alteration and reconstruction,OISD Std.129 forTANK - API 650/653/620 Oil Storage Tank Design andAPI-650 addresses the design,fabrication,erection,and testing requirements of above-ground,welded steel,atmospheric storage tanks.(API-653 is discussed below.)
