Once the required 'root gap' is acceptable,the weld joint will be secured by welding 'finger bars' (2x6x3/8cs) across or transverse to the vertical joint.Several finger bars will be used per weld joint.These are used in leiu of tack welding the joints.All the vertical joints will be fit-up before weldingfrangible roof tank as per api 650 - API (American You are correct that these items are based on an self anchored tank.However,the addition of anchorage does not significantly affect the shell-to-bottom joint strength with regards to rupture of the corner weld.The roof-to-shell joint must overcome the weight of the roof,the pitch of the roof adds strength,and there is a rim angle to [DOC]Section 23 10 00 - FACILITY FUEL SYSTEMS self anchored storage tanks fusion welded joints#0183;Web view5.This specification covers all aboveground and underground fuel oil storage tanks,including day tanks.6.VA National CAD Standard for underground oil storage tanks,30,000 liters (8,000 gallons) and above.
